Metal Casting & Forging

SOLVIT Shanghai Automobile Parts

Metal Casting is the process of heating metals until they are molten, pouring or injecting the metal into a mold, and removing the solidified (frozen) article which retains the shape of the mold. Secondary processes such as machining to complete the parts if needed.

There are two general categories of casting, expendable mold and permanent mold. Expendable mold casting includes a variety of methods, all of which the molds are made and used for one cycle, producing one viable casting. Sand casting and investment casting are two expendable mold processes SolvIT utilizes.

For the permanent mold process SolvIT uses Die Casting for most projects unless the parts are very large.

Permanent mold casting generally provides a smoother surface and smaller dimensional tolerance on the cast parts than expendable mold casting, but there are exceptions, such as the expendable mold process of investment casting.

Forging is the process of forming metal, in either cold or heated states, using sets of dies, and hammer presses. Hot forging is generally used to obtain a basic shape for subsequent cold forging finishing, and/or machining.

Hot forging is particularly useful for making machining blanks, reducing waste of machined parts.

Cold forging can enhance the strength of critical load components such as connecting rods, and other engine and drive train parts.
