The quality of precision castings is mainly affected by the following four factors

As a commonly used product in our daily life, the quality of precision castings is mainly affected by the following four factors:

1. The design process of iron castings. In the design, in addition to determining the geometry and size of precision castings based on working conditions and metal materials, the rationality of the design should also be considered based on the process characteristics of precision castings and casting alloys to avoid precision castings. Deformation, cracking and composition analysis.

2. The casting process must be reasonable, that is, the appropriate shape and core method should be selected according to the structure, size and weight of the cast iron parts. In order to ensure the quality of the cast iron parts, the cold iron, outlet and gating system should be reasonably set up.

3. Is the quality of the casting raw materials good? If the quality of the metal furnace materials, solvents, modifiers or coatings does not meet the standards, defects such as pores, slag inclusions, and sand adhesion will appear in the cast iron parts, which will affect the internal and external quality of the cast iron parts.

4. The process operating procedures must be reasonable. When precision castings are made, the technical level of workers must be continuously improved, and reasonable process operating procedures must be formulated to make the production process correct and reasonable.
