Characteristics of die casting process

Die used in die casting process is usually made of alloy material with higher strength than processed parts. This process is similar to injection molding. The cost of casting equipment and mold is generally high, so it is not suitable for processing small batch parts. However, as the use of die casting to process parts is relatively simple, only four main steps are needed, and the single cost increment is very low, so it is very suitable for the manufacture of large quantities of parts. In addition, the die casting is more flat than the other casting techniques and has a higher size consistency. Therefore, the die-casting is a widely used one of all the casting processes.

General features of die parts design

In the die design output, the 3D modeling is used to describe the structure of the mold and the basis for the NC machining, and the two-dimensional drawings are the basis for the design of the parts processing technology. Therefore, the design of mold parts requires the output of two-dimensional drawings of mold parts. Mold parts processing technology design, not only conforms to the general characteristics of machining process design, but also must make flexible adjustment according to its own special requirements. Its general features include several aspects:

Identification and determination of datum

The design datum of mold parts includes two parts: Part datum and machining datum. The part datum describes the assembly surface of the parts, and the machining datum should generally coincide with the parts datum.
