Hydraulic Press Machine for Stretch Draw Forming
The process of deep draw forming starts with the creation of metal blanks. The blanks are formed by a pressing machine, which uses specially designed molds to cut the metal sheet in the required and size. For metal sheets form efficiently, the blanks may be placed on the reel. In each step of the deep drawing process, the metal blanks are shaped through the application of pressure by the metal die.
But deep drawing can be a bit complicated process. So you need to get everything right to get the desired product. There are two main factors that you need to consider: Material selection and lubricant selection. For material selection, you need to consider the tensile properties of the metal sheet. This is a crucial factor as it determines that the tonnage or pressure applied. For the lubricant, get an oil film that prevents scratches and reduced friction. The oil should be removed efficiently after completing the operation.
The cost of manufacturing parts with deep drawing is significantly low compared to similar processes. Even when producing in small volumes, this forming technique will still be more cost-effective. When it comes to the strength of the products, this technique offers the best features. You will have stronger parts and minimal weight. These are just some of the benefits that make deep drawing a better alternative.
Deep drawing technique work on a vast range of metals to manufacture all shapes of open hollow thin-walled parts. The technique can work both ferrous and non-ferrous metals. Some of the metals that can be used for to manufacture products through deep drawing include aluminum, brass, bronze, cold-rolled steel, copper, invar, iron, Kovar, molybdenum, nickel, silver, stainless steel, tungsten and their alloys.
