Basic types of sand casting process parameters

The fundamental types and meanings of sand casting process parameters. PDP is used to express the design parameters of the sand casting process. The three types of process parameters can be described and defined based on the different attributes of process parameters as follows:

- Independent process parameters of sand casting: These are the parameters that can be directly determined by product drawing and enterprise production process conditions in the sand casting process design and are expressed by IP, such as wall thickness, draft angle, machining allowance, and other process parameters.

- Sand casting coupling process parameters: These are the parameters that can only be determined based on other determined process parameters in the sand casting process design and are expressed by CP, such as casting temperature, cooling time, and other process parameters.

- Inherent attribute process parameters of sand casting: these are the parameters that determine the material properties in the sand casting process design and are expressed by IAP, such as metal brand, molding sand type, and other process parameters.
