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:
- 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:
- Food and beverage packaging
- Medical and pharmaceutical
- Oxygen services
- Petrochemical production and distribution
- Water treatment
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:
- Powder coating
- Bead blasting
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:
- Heavy equipment production
- Industrial process equipment
- Medical devices
Manufacturers also use a number of processes to permit tapping for machine screws and to accommodate deeper extrusions. Some of these processes include:
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.

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:
- Aerospace instruments like altimeters
- Aneroids for oxygen systems and automatic deployment systems
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.
