Extrusion is a process that involves pushing material through a die or mould in order to create a shape or cross-sectional profile. This process can be used with both metals and plastics and is often used to create parts with an even wall thickness or profile. It is also very versatile, as it can be used to create both simpl…See more on blog.thepipingmart

The best deep-drawing performance often is achieved by using carbide draw rings or hard aluminum-bronze tooling inserts. Extreme-pressure lubricants are essential for deep drawing stainless steel but soluble oil can be used with aluminum-bronze tooling. Common practice should include lubricating both sides of the blank to reduce galling tendency.
