Aluminum Extrusion Casting

Product Description 

This kind of Aluminum Extrusion Casting also known as "liquid die forging", is a method of pouring molten or semi-solid metal into a metal mold and then applying it to the original to solidify under pressure so as to obtain a blank or part. It can improve material utilization, increase the mechanical properties of material as well. In addition, the Aluminum Extrusion Casting has the properties of simple operation, high productivity, low investment, high efficiency as well as labor saving. It can be used to making long rod, thin wall, deep hole, and there is no need for cutting process. 

The essence is the molten metal crystallizes under the action of mechanical external force, and is accompanied by a small amount of plastic deformation.  What’s more, the Aluminum Extrusion Casting is suitable for thick-walled castings with high mechanical properties and air tightness requirements, such as aluminum wheels for automobiles and motorcycles; aluminum pistons, aluminum cylinders, aluminum cylinder heads, aluminum transmission cases for engines, etc.

Feature

This Aluminum Extrusion Casting is a process completed on a dedicated die casting die forging machine. In addition to producing traditional casting materials, it can also use deformed alloys and forged alloys to produce parts with very complicated structures. The metal liquid is first cast into the cavity of the mold at a low or high speed. The mold has a movable cavity surface. It is forged under pressure as the metal liquid cools, which not only eliminates the shrinkage and shrinkage defects of the blank, but also makes the internal structure reaches the forged broken grains. The comprehensive mechanical properties of the blank have been significantly improved. The tensile strength is nearly double that of ordinary cast alloys. It has more positive significance for parts such as aluminum alloy automobile wheels and frames that are expected to be produced with higher strength and impact resistant materials.
