The liquid metal is cast into the casting cavity suitable for the shape of the part, and after cooling and solidification, the method of obtaining the part or blank is called casting. The casting method is used to obtain castings called castings. So we know what is the general technical requirements of casting parts? The following casting parts foundry to briefly introduce.
General technical requirements for casting parts:
1. Material requirements. Mainly hardness, tensile strength, elongation, impact toughness.
2, dimensional accuracy and shape accuracy. Different castings have different requirements, using different dimensional and geometric tolerance standards and different tolerance levels.
3. According to the requirements of use, the acceptance requirements for other defects of castings shall be stipulated. Such as pores, blisters, shrinkage cavities, shrinkage porosity, slag inclusion, sand inclusion, cracks, etc.
The liquid metal is poured into a mold cavity that is compatible with the shape and size of the part, and is cooled and solidified to obtain a blank or part called a casting part.
