Castings, as products that we often use in our daily life, are affected by the following four factors.
Castings, as products that we often use in our daily life, are affected by the following four factors.
First, cast iron parts design processability. When making design, in addition to determining the geometry and size of castings according to the working conditions and metal materiality, it is also necessary to consider the rationality of design according to the angle of casting process characteristics and casting alloy to avoid defects such as deformation, cracking and composition deviation of castings.
Second, the casting process should be reasonable, that is, according to the structure, size and weight of cast iron parts to choose the appropriate modeling, core making method. And the cold iron, riser and pouring system should be reasonably set to ensure the quality of cast iron parts.
Third, the quality of raw materials for casting is excellent or not. If the quality of materials such as metal furnace, solvent, degenerate or paint is not up to the standard, it will make the cast iron parts have defects such as porosity, slagging and sand sticking, thus affecting the internal and external quality of cast iron parts.
Fourth, the process operation procedures should be reasonable. When making castings, the technical level of workers should be improved continuously, and at the same time, reasonable process operation procedures should be formulated to make the production process correct and reasonable.
