  1. Overview of Metal Pressure Transducer Diaphragms

    Leave a Comment

    A diaphragm pressure transducer is a mechanical device that converts pressure changes into an electric signal, which can be measured to gauge changes in pressure. Diaphragm pressure transducers are particularly useful for low pressure applications.

    How Does a Pressure Transducer Work?

    Pressure levels and fluctuations are registered through deformation of a diaphragm and attached gauges. The displacement of the diaphragm and gauges is proportionally converted into electrical current. That electrical signal is analyzed to determine accurate pressure measurements.

    Diaphragms for pressure transducers can be composed of either metal or non-metal materials. Non-metal diaphragms are durable but tend to be less elastic than metal diaphragms. This makes them less desirable for applications which require precise measurements with low flow volume.

    What is a Metal Diaphragm?

    Metal diaphragms are circular plates composed of thin, flexible metal that exhibit deformation when under pressure. Diaphragms are used for both sealing and pressure transference. Diaphragm seals prevent fluid from leaking into other parts of the system while simultaneously preventing contamination of the fluid itself. Within a pressure sensor, diaphragms isolate the system and transfer the effects of pressure changes to the gauges, where the changes are converted into electrical current for analysis.

    Two Main Types of Solid Metal Diaphragms

    Metal diaphragms can be specially tailored to meet the needs of a wide range of industries and applications. There are two primary metal diaphragm designs: High-Sensitivity Low-Pressure (HSLP) and Low-Sensitivity High-Pressure (LSHP).

    What are High-Sensitivity Low-Pressure Diaphragms?

    HSLP diaphragms are used for applications that require the diaphragm to operate with a great deal of flexibility under low-pressure conditions. They are more frequently used than their LSHP counterparts and are particularly useful for low-pressure applications that require a high degree of precision, such as food production and pharmaceutical manufacturing.

    What are Low-Sensitivity High-Pressure Diaphragms?

    LSHP diaphragms must be more rigid and capable of retaining their shape and position in high-pressure applications. Their durability makes LHSP diaphragms valuable as protective barriers in high-pressure equipment. They can also be particularly useful for the conversion of pressure displacement into electronic signals. LHSP diaphragms are often designed to open at precise pressures, making them useful for applications which require highly accurate pressure measurements. Pressure-based medical equipment and systems that operate in extreme environments also benefit from the use of LHSP diaphragms.

    Types of Tooling for Metal Diaphragms

    At Hudson Technologies, we use two highly specialized tooling methods to manufacture quality metal diaphragms. The method used depends greatly on the intended thickness of the component and expected production volume.

    Metal-to-Rubber Tooling

    For prototyping, sampling, and lower production volumes of less than 50,000 annually, metal-to-rubber tooling is appropriate for diaphragms with a thickness greater than 0.0015 inches. This process is less expensive than other tooling methods, and ideal for swift small-scale production of highly accurate components.

    Metal-to-Metal Tooling

    Metal-to-metal tooling is ideal for production volumes that exceed 50,000 components annually, and for diaphragms with a thickness less than 0.0015 inches. This type of tooling can be relied upon to produce highly accurate components within tight tolerances for burr height, part configuration, and durability.

    Applications and Capabilities of Metal Diaphragms

    Metal diaphragms are highly versatile and have a broad range of uses in mechanical and industrial equipment, medical devices, and pressure transducers. Common uses of metal diaphragms include:

    • Pressure regulators
    • Conversion of movement into electrical signals
    • Protective fluid barrier
    • Flexible membrane for fluid pumps
    • Protective barriers and failure points

    Due to their combined durability and flexibility, metal diaphragms can endure repetitive cycling for millions of strokes and are capable of operating accurately in extreme environments where they may be exposed to broad temperature fluctuations, corrosive materials, and extreme pressure.

  2. History of Titanium and Its Applications

    Leave a Comment

    The history of titanium stretches way back to 1791 when it was discovered by a pastor in Cornwall, England. However, it wasn’t until 1910 that it became prominent on the manufacturing scene when metallurgist Matthew A. Hunter began producing it in the United States. As the ninth most abundant element on earth, it can be found in minerals like rutile and sphene.

    As strong as steel but only about half as heavy, titanium alloys are used extensively in the aerospace and automotive industries, not only for its lightweight strength, but also because titanium is durable and not susceptible to corrosion. This versatile metal also is used for bone setting, artificial hips, and other medical implants for the human body.

    History of Titanium

    It wasn’t always called titanium. Originally, it was known as gregorite—named after the Reverend William Gregor who discovered it in 1791. The good pastor was an amateur geologist in his free time, and he had been analyzing some magnetic black sand when he realized he’d happened upon a new metal. Two years later, it was “discovered” again, this time by a German chemist who called it titanium, a nod to the strength of the Titans from Greek mythology. In 1797, he realized his titanium was the same as the aforementioned gregorite, but it still took more than 100 years before titanium was successfully isolated and put on its path to be used in all the products you can find it in today.  Now the 22nd element on the periodic table, titanium is useful in a wide range of industries due to its strength, corrosion resistance, and compatibility with the human body. 

    History of Titanium

    Titanium Applications

    Titanium is popular in any situation where it’s important to maintain a high tensile strength to density ratio, such as automobiles, airplanes, spacecraft, naval ships, and motorcycles. It’s also valuable in these uses because it improves durability, fuel efficiency, and safety. You’ll find titanium across the aerospace, industrial, medical, and architectural industries as well as in a variety of consumer products, like tennis rackets, golf clubs, helmet grills, lacrosse stick shafts, and bicycle frames. It’s used in surgical instruments and medical implants, wheelchairs, crutches, and more in the clinical setting. 

    When compared to steel, titanium is equal in strength but lighter in weight. When compared to aluminum, titanium is somewhat heavier, but twice as strong. Depending on the situation, it can be an ideal alternative for either of those materials. 

    Let’s look more closely at the uses for titanium in two major industries: aerospace and medical.

    Titanium in Aerospace and Medical

    In the aerospace industry, common uses for titanium include:

    • Rotors
    • Compression blades
    • Hydraulic system components
    • Armor plating
    • Naval ships
    • Spacecraft
    • Missiles
    • Structural parts
    • Landing gear
    • Helicopter exhaust ducts

    The Grade 5 Titanium alloy or 6AL 4V (6% Aluminum, 4% Vanadium) is used in nearly 50% of all aircraft applications, from engines to frames, valued for its corrosion resistance, heat resistance, maintainability, and lightweight strength. 

    Titanium is biologically compatible with the human body, meaning that the body does not try to reject it. It also has the natural ability to integrate with the bones in the body to create a permanent structure. This makes it useful for a wide range of medical device components including medical and dental implants, medical instruments, and beauty supplies:

    • Heart valves
    • Plates, pins, rods, and cages surgically implanted in the body
    • Hip and knee replacements
    • Needles, surgical tweezers, scissors, forceps, etc.
    • Tooth implants
    • Hearing aids
    • Spinal fusion cages

  3. The Advantages and Process of Forming Deep-Drawn Aluminum Parts

    Leave a Comment

    Aluminum’s properties grant it many advantages that differentiate it from other metals. Aluminum is versatile, sustainable, and recyclable, and it’s only about one third of the weight of steel.

    Deep-drawn aluminum parts are becoming more and more popular among manufacturers and customers alike. Some benefits associated with deep-drawn aluminum include:

    • The ability to be used in a wide range of applications
    • High impact and rust resistance
    • An exceptional strength-to-weight ratio

    These properties have made it a popular choice for applications in the aerospace, automotive, and medical industries, to name just a few.

    Advantages of Aluminum Components

    Deep Drawn Aluminum Parts

    Deep-drawn aluminum part manufacturing can provide customers with a wide variety of advantages. The following are some key benefits that come with this process:

    • Some aerospace products can only function within certain weight tolerances. Because aluminum offers a high strength-to-weight ratio, it’s an ideal alternative to steel in such cases.
    • Outer-body automotive panels are always at risk of becoming dented from impacts and collisions. Deep-drawn aluminum’s high level of dent resistance means that it takes more force to dent aluminum panels than those formed from other metals.
    • Aluminum is fully recyclable, meaning that even when an application has reached the end of its service life, the raw material does not have to go to waste.
    • Aluminum’s natural corrosion resistance means that it doesn’t have to undergo extensive, regular treatment, and it can withstand a lot of environmental wear on its own.
    • Aluminum is known to be an electrical and thermal conductor of the highest order.
    • Deep-drawn aluminum parts are very cost-effective, and they can be adapted to work well for both low- and high-volume production runs.

    The Process of Forming Deep-Drawn Aluminum Parts

    Aluminum stamping compresses aluminum into specified shapes and forms. Deep drawing offers many advantages over aluminum stretching because aluminum is a highly inelastic material. The deep-drawn aluminum forming process is made up of several steps.

    At the start of the deep drawing process, an aluminum part is pulled, or drawn, into a stamping machine’s die cavity. The cavity depth equals or exceeds the minimum part width. The operator must ensure that an acceptable draw ratio is in play, since metal in compression tends to resist flow. Subsequently, the deep drawing process employs radial tension-tangential compression to form the metal into the desired shape.

    This process turns flat sheet metal, also known as “blanks,” into hollow cylindrical or box-shaped enclosures with straight or tapered sides. End products can also be in the form of a combination of tapered, curved, and straight sides.

    A series of dies redraws the enclosure and gradually reduces its diameter while increasing its length. While these operations are in effect, the part’s wall thickness undergoes minimal change.

    Since deep drawing is a cold working process, one side effect of these operations is a hardening of the aluminum material, which makes it tougher and more durable. Additionally, the grain structure of the aluminum undergoes changes as the blank forms and stretches into its final shape. This also boosts the aluminum’s strength capabilities.

    A Leader in Deep-Drawn Aluminum Manufacturing

    Deep-drawn aluminum part forming offers a number of key advantages for end application usage. This process can supply customers with durable, high-quality, and cost-effective parts to meet their business needs.

    Hudson Technologies is a leading manufacturer of deep-drawn aluminum components. We take great care to ensure that our parts meet precise customer specifications and are delivered within reasonable lead times.

  4. Applications of Different Processes

    Leave a Comment

    Metal finishing refers to the process of coating metallic parts with a thin metal coating. Metal finishing is an umbrella term, covering processes that include:

    • Cleaning
    • Polishing
    • Plating
    • Buffing
    • Brushing
    • Grinding
    • Vibratory finishing

    Many metal finishing processes rely on the use of electroplating, during which metal ions are deposited onto a substrate via an electric current. In this post, we analyze a few of the different metal finishing processes and discuss the best scenarios in which to deploy them.

    Metal Finishing Applications for Aqueous Cleaning and Degreasing

    The metal finishing industry uses a range of techniques that enable manufacturers to improve their metal products.

    Aqueous cleaning and degreasing allow manufacturers to efficiently clean and polish metal parts. This process uses detergents and acidic solutions to remove burrs, oils, organic compounds, waxes, and other debris from finished parts.

    Deburring is the process of removing imperfections from the surface of a metal product. This excess material, called burrs, can mar the aesthetic of the piece and compromise its fit and function. Aqueous cleaning processes have other important applications, including:

    • Removal of scales from heat treatment
    • Radius formation
    • Removal of chemicals and residues from the manufacturing process
    • Smoothing and evening surfaces
    • Preventing and removing rust and corrosion

    This process is also used to passivate metals and components.

    Aqueous cleaning processes work well for manufacturers in industries such as:

    Using Surface Finishing in Industrial Manufacturing Processes

    Surface finishing allows precision fabrication of parts that appear in a diverse array of industries. These procedures include:

    • Polishing
    • Anodizing
    • Painting
    • Powder coating
    • Bead blasting
    • Plating

    Using these techniques, manufacturers can derive the following benefits when performing postproduction processing on their metal parts:

    • Improved corrosion and chemical resistance
    • Improved paint adhesion when metal finish is used as a primer
    • Strengthened substrate and improved wear resistance
    • Reduced effects of friction
    • Improved part appearance
    • Increased solderability
    • Electrically conductive surfaces

    For these reasons and more, many industries rely on surface finishing for their metal products. Some manufacturing sectors that benefit most from these techniques include:

    • Aerospace
    • Defense
    • Heavy equipment production
    • Industrial process equipment
    • Medical devices
    • Semiconductors
    • Telecommunications
    • Transportation

    Manufacturers also use a number of processes to permit tapping for machine screws and to accommodate deeper extrusions. Some of these processes include:

    • Piercing
    • Extruding
    • Bulging
    • Coining
    • Tapping
    • Machining

    These techniques help products in the medical, aerospace, battery production, and electronics industries optimize their efficiency and effectiveness.

    Welding Techniques for Industrial Processes

    Resistance spot welding techniques like TIG, laser, and brazing can be applied to industrial manufacturing in a number of ways:

    • Spot welding replaces riveting when joining thick steel plates. This reduces unsightly seams and improves the integrity of the joint.
    • Without the need for gas-tight joints, mechanically joining multiple sheets of metal becomes more economical.
    • Spot welding is useful for attaching parts like braces, pads, clips with cases, bases, covers, and other components made from sheet metal forming.

    Welding applications are frequently used in these industries.

    • Construction of automotive frames, body parts, add-ons, doors, and tailgates
    • Commercial vehicles
    • Railway conveyances

    Military and defense manufacturers frequently employ welding techniques in their production processes. Companies in the sheet metal forming industry also rely on these methods to create and secure their products.

    Custom Metal Finishing Services from Hudson Technologies

    Metal finishing is a set of techniques that allow manufacturers to customize their products to look and work in specific ways. Aqueous cleaning, surface finishing, and welding are just a few of the processes manufacturers can use to affect the function and appeal of their components.

    Hudson Technologies partners with manufacturers in a range of industries to produce finished metal parts. We offer design, production, prototyping, and consulting services that help your business produce high-quality parts and products without increasing production costs.

  5. The Two Main Types of Solid Center Metal Diaphragms and How They’re Different

    Leave a Comment

    Metal diaphragms are specially engineered components that fulfill several critical roles across many industries. Generally nothing more than thin, circular plates, diaphragms help regulate pressure levels in complex machinery systems.

    What renders these plates so critical to countless processes is their ability to change their shapes as needed. Diaphragms undergo elastic deformation when subjected to axial loading or pressure, and this allows them to play many different roles.

    Typical roles of solid metal diaphragms include:

    • Regulating pressure
    • Converting movement into measurable communication with equipment
    • Creating a physical barrier between opposing forces involving gas and liquid
    • Acting as a membrane while fluids are pumped
    • Serving as predictable failure points to protect equipment from the risk of overpressure
    • Cycling for millions of strokes
    • Providing reliable performance in corrosive environments and extreme temperatures

    Metal diaphragms exist in two main forms: high-sensitivity low-pressure (HSLP) diaphragms and low-sensitivity high-pressure (LSHP) diaphragms. Understanding the differences between the two is crucial to finding the best fit for your applications.

    High-Sensitivity Low-Pressure Diaphragms

    HSLP diaphragms appear in applications that require the diaphragm to move a significant amount without necessitating a sizable application of pressure. These devices most frequently help with pressure sensor isolation, especially in the food processing and pharmaceutical industries.

    Both these industries use HSLP diaphragms to protect fluids from contamination through the use of pressure sensors. These sensors are activated by excess pressure within the system, allowing machinery to automatically channel fluids when the pressure reaches a certain threshold. In food processing and pharmaceutical applications, HSLP sensors allow fluids to advance to the next stage of processing only when they have reached the desired volumes, helping operators precisely control the mixing and processing of various substances.

    Many other industries requiring ultra-pure process fluids also take advantage of pressure sensors, and therefore rely on HSLP diaphragms. Some other common applications of these systems include:

    Low-Sensitivity High-Pressure Diaphragms

    LSHP diaphragms best suit applications that require the diaphragm to remain in place even under high pressure. Although they appear less frequently than HSLP diaphragms, they play just as important roles in regulating pressure in fluid-based systems.

    LSHP diaphragms especially aid in converting movement into computer-readable communications. They can be calibrated to only open at precise pressures, allowing operators to take accurate measurements throughout their use.

    They’re also often implemented as gas–liquid barriers and failure points because they can operate as a last line of defense against overpressure and machine failure. Their abilities to perform well in extreme conditions also make them beneficial to medical device manufacturers, who use LSHP diaphragms to regulate pressure-based equipment.

    Low-Pressure High-Value Procurement From Hudson Technologies

    At Hudson Technologies, we design a wide range of HSLP and LSHP diaphragms for many applications. We build customizable diaphragms from materials including:

  6. Farley’s Top Five Things to Know for Deep Draw Metal Stamping

    Leave a Comment

    The deep draw process itself begins once a flat piece of metal – referred to as a blank or a disc – is placed over a cavity known as a die. A punch pushes the metal through the die to form it into the specific shape required by the design. Deep drawn metal stamping has a wide range of applications across myriad industries, so an understanding of how the process works can benefit many different types of industrial stakeholders.

    Top Five Things to Know for Deep Draw Metal Stamping

    Deep drawn metal stamping – or simply deep drawing – requires a specific skillset and experience to accomplish correctly. Our resident expert Farley Fitzpatrick, compiled the following five tips for deep draw metal stamping.

    1. Cold Metal Drawing

    Cold metal drawing processes will provide you with a greater peace of mind. Cold processes are able to provide finished products with a greater accuracy. Cold metal drawing also offers better grain structures and surface finishes in the final product. While more expensive, cold drawing results in a blanket, overall improvement of the metal’s properties when compared to other methods.

    1. Corner Radii

    To determine the smallest corner radius that you can obtain, there’s a general rule you can follow: The smallest attainable corner radius is equal to the material thickness times two. Working additional draw operations into your process can help you skirt this rule a little if you need to further reduce corner radii. For many designs, larger corner radii may be considered desirable. These may also reduce the amount of draws necessary.

    1. Draft

    A small amount of draft is absolutely necessary to the drawing process. The draft allows the case to be stripped off of the punch after draw operations are completed. This makes for a container that’s smaller on one side and larger on the other—the closed end inside will be smaller and the open end inside will be larger. Our standard draft is 0.001″ (0.025mm) per inch of length.

    1. Work Hardening

    Cold working of the metal during the deep draw process (also known as work hardening) must be relaxed through a heat treat process. This second process is known as annealing. It’s an intermediate step that takes place during the forming and case reduction sequence.

    1. Ironing

    Specifically designed tooling can intentionally thin out (or iron) the sidewalls beyond the material’s natural tendencies. This method will only be used to address particular requirements and occurs on a project-by-project basis. This process can add greater dimensional stability to the case while also making it more aesthetically pleasing.

    The deep drawing process is crucial to the fabrication of items that many of us use every day, such as pots and pans, automobile parts, and containers. Since deep drawing plays such a central role in getting so many objects made, it’s key for those involved in the process to understand it thoroughly.

  9. Battery Enclosures for Military Applications

    Leave a Comment

    Batteries form critical components of many active weapon systems in military and defense projects. Because batteries contain toxic substances and must be kept in working condition, defense contractors are turning to battery enclosures as a crucial means to preserve the health of their systems. Keeping the batteries enclosed and protected ensures optimal performance, reliability, and safety. 

    Why You Need Battery Enclosures

    A faulty battery could jeopardize an entire mission. Military industry products often experience harsh conditions including extreme temperatures, intense vibration, ultraviolet radiation, and high G-forces.

    Proper enclosures keep batteries safe and hermetically sealed. They protect against outside threats like sand grit or chemical attacks, reducing battery wear and prolonging system lifespan. Battery enclosures also help with temperature control both outside and inside larger mechanical systems that feature varying internal conditions.

    Proper enclosures also protect the battery from high G-forces involved in flight operations or sudden stops. Vibration, which could cause some pieces of the battery to come loose or stop functioning, can also be mitigated with the proper enclosure. Every defense application places a high premium on mission success, meaning that manufacturers should take as many steps as possible to reduce the risk of battery failure.

  10. A New Generation of Pickup Covers

    Leave a Comment

    Lace Music Productions, a division of Actodyne General, Inc., was founded in 1979 by Don Lace, Sr.  Don had extensive experience in high intensity lighting, speakers, and magnetics, and an early focus of Don’s was designing and manufacturing solenoids.  Coil winding was at the heart of his business.

    In 1967 his path crossed with Fender Musical Instruments, where he was exposed to the fascinating world of the music industry.  After starting Actodyne General, Don found out that Fender was experiencing a high rejection rate during the production of traditional style guitar pick-ups that were made at the time.  Eager to become more involved in the music industry, Lace began to develop a new guitar pickup that would have a lower rejection rate during production. Lace used one of his existing solenoid patents that was in part a transducer, and partially an open-and-closed device called a shock generator.

    Lace applied the new concept to an old beat up Sears guitar that he bought at a garage sale. He plucked the string and it worked.

    By the late 1980’s, Lace had perfected a single rectangular-shaped sensor that fit under the strings. Lace presented this technology to Seth Lover (inventor of the original humbucking pick-up), who was working with Fender at the time. The goals were simple:

    1. Reduce the rejection rate
    2. Increase fidelity
    3. Reduce outside hum.

    Lover knew that Lace was really onto something.  Fender began to use the new technology and feature the Lace design guitar pick-ups on their own products. Known as Fender-Lace Sensors, these electric guitar pick-ups were originally made for the Fender Strat Plus guitar, which won numerous awards. Today they can be found on many other Fender guitars and are available in Gold, Silver, Blue, or Red series as either single or dually models that function as a double-coiled humbucker.

    Hudson Technologies and the Lace Brothers

    Sadly, Don Lace, Sr. passed away on October 11, 1992, leaving a strong impact on the music industry. To this day, his two sons, Don and Jeff carry on his tradition of solving complex problems and developing solutions for the equipment used in everyday music. By creating cutting-edge products that capture the sound and soul of classic vintage originals, the Lace Music team continues to lead the music industry by creating innovative products for guitar, bass, and many acoustic stringed instruments.

    The relationship between Hudson Technologies and the two brothers is very interesting.  When they were young, their father would order parts from Hudson (Hudson Tool & Die at that time) using the printed catalog.  In some of the older Hudson catalogs, pictures were created of “cityscapes” using Hudson cans as buildings.  Some examples of these may be found here:

    Don and Jeff used to cut these pages out of the catalog and play with them, driving matchbox cars through the can cities. As they got older and joined the family business, they mimicked some of Hudson’s can city pictures and made their own version of cityscapes using their own Actodyne General coil products as the buildings.

    Lace Music and Hudson’s paths crossed again in 2016 in a very interesting way. John Marfiak, Hudson’s Director of Sales, was walking the huge NAMM (National Association of Musical Merchandisers) Show in Anaheim, California. He was looking for companies for which Hudson could provide covers for their guitar pickups or humbuckers.  John Marfiak met Don Lace at the Lace Music booth and business cards were exchanged.

    “When Don saw my card, his eyes lit up,” said Marfiak.  “He said to me: ‘You’re Hudson Tool & Die!’  He told me about the fun he had playing with our catalog pages as a youngster.”

    After several meetings with the Lace brothers, orders were placed for a new generation of pickup covers. Don redesigned the covers to have thicker brass walls and to emboss the words “Lace Sensors” onto the part. The redesign and ordering process went smoothly, and before long the first shipment of the new parts arrived at the Lace facility in Cypress, California.

    The Lace brothers were very pleased with their new parts and shared a picture of the newly opened box on Lace’s Facebook page for their followers to get an early look at the new product. Lace Sensors continues to improve their product offerings and stay at the cutting edge of the music industry.

    Lace Music recently got into a new market segment: making pick-ups for cigar box guitars. Cigar box guitars have a huge following and Lace has the first pick-up in the industry that was specifically designed for a cigar box guitar. This pick-up looks like a matchbook and fits perfectly on a cigar box guitar.

    The Lace / Hudson story goes back a long time, and hopefully this partnership will continue for many more years. To discover more about their products, visit Lace Music. Also check out Hudson Technologies to learn more about our fabrication services and how we can support your design.
