Deep drawn metal stamping is a manufacturing process that competes with several other processes that create the same or similar products. However, the deep draw process has several significant differences that set it apart from those other methods. Without being an expert on manufacturing, you could fall victim to hearing false myths about deep draw, so we’re going to be debunking a few of them today.
- The cost is too high. Simpler methods are cheaper.
False. Deep draw is a continuous process, making it one of the fastest and most cost effective available. Using the deep draw process, the cost per unit decreases as the number of parts produced increases.
- Deep drawn stamping can only create simple parts.
False. Deep drawn metal stamping is capable of creating highly complex geometries to very tight tolerances. Multi-station stamping presses are capable of forming axisymmetric parts that are seamless, strong, and light.
- High tech = high cost.
False again. From an operational standpoint, deep drawn metal stamping is one of the simplest and most robust processes available. Low technical labor costs and high production time combine to make the deep drawn process easy and profitable to manage.
- Materials are weakened by deep drawing.
While understandable, this myth is still false. A common misconception is that deep drawing stretches the material and therefore damages it. The reality is that the force but on the material only increases the overall strength through a process known as cold working. While some elongation may occur, actual stretching of the base material is very slight. In the end, the finished part is actually stronger than the original material.
While there are more misconceptions out there, these are the top four myths about deep drawn metal stamping and the deep draw process. For more Hudson Technologies FAQs, check out our Ask Farley section, where our all-around deep draw guru, Farley Fitzpatrick answers questions sent into us.
