Brass Extrusions: Understanding How Extrusion Works and Why It Is a Lucrative Molding Option
Before the metal parts in your car engine, plumbing system, or even the device where you’re reading this from became the intricate construct that they are now, they first underwent a series of arduous processes. Perhaps the most critical of these is molding, as it is in this stage where a metal’s final form is decided.
There are numerous methods for molding metal but arguably the most efficient is extrusion. This method involves forcing a piece of metal (also called “work piece”, at least in metalworking) into a die, a tool that has holes with cross sections smaller than the work piece. The portion of the work piece that is allowed to pass through the die becomes the final product, called extrusion.
Benefits of Extrusion
Molding metals is an expensive business. Casting (one of the costliest methods), for instance, involves melting metal and pouring it into a mold. To achieve this, tremendous amounts of fuel are required to keep the blaze in the furnace going, and there’s a constant need for a new mold. Extrusion, on the other hand, reduces if not completely eliminates the need for both metal melting and mold production. No extreme heat is needed; just enough heat to force the metal into the die, and a special kind of compressor. The die is pretty much reusable so manufacturers don’t have to keep making new ones.
