Rapid Tooling

Extrusion die called pull - up die, the products are mostly aluminum alloy. Extrusion die is calculated as a unit of tonnage, conventional extrusion die with thousands of tons of extruder molding, and more than 500 mm of the shape of the surface to use ten thousand tons of extruder. The manufacture of extrusion die is mainly based on cutting processing and heating processing. After calculating the shrinkage rate of the mold, the large plate is directly used for linear cutting processing, and then the mold is put into a variety of extrusion machines with different requirements for the extrusion of soft liquid aluminum. Aluminum products produced by extrusion die are mostly semi-finished products, which need secondary CNC machining or lathe, slitter machining and then surface treatment process producs.
