  • Do Metal Castings Need Heat Treating

    Age hardening is a technique where heat is applied to the casting for a long time (as long as 20 hours). It’s a complicated process that, in simplistic terms, blocks the molecule’s ability to dislocate freely resulting in much less ductile material and much higher yield strength.

  • Heat Treatment INVESTMENT CASTING

    Heat treatment is one of the main technologies during investment casting process. After heat treatment, it will not change the shape and whole compositions of investment castings, but will endow or improve the ing performance of products by change the inner microscopic structure, or change surface compositions of investment castings .

    Durville Process Casting. The most common form of tilt casting is a process with the unique feature that, in principle, liquid metal can be transferred into a mould by simple mechanical means under the action of gravity, but without surface turbulence. It therefore has the potential to produce very high quality castings.

    Metallurgy Metallurgy Casting: Casting consists of pouring molten metal into a mold, where it solidifies into the shape of the mold. The process was well established in the Bronze Age (beginning c. 3000 bc), when it was used to form most of the bronze pieces now found in museums. It is particularly valuable for the economical production of complex shapes, ranging from mass-produced parts
