china Forktip Casting company analyzes the factors of casting quality
China Forktip Casting company found that there are many factors that affect the quality of castings, the first is the design process of castings. When designing, in addition to determining the geometric shape and size of the casting according to the working conditions and the properties of the metal material, the rationality of the design must also be considered from the perspective of the casting alloy and the characteristics of the casting process, that is, the obvious size effect and solidification, shrinkage , stress and other issues, China Forktip Casting company reminds to avoid or reduce the composition segregation, deformation, cracking and other defects of castings.
Second, there must be a reasonable casting process. That is, china Forktip Casting company selects the appropriate parting surface, shape, and core-making method according to the structure, weight and size of the casting, the characteristics of the casting alloy and the production conditions, and reasonably sets the casting bars, chills, risers and gating systems. To ensure high quality castings.
china Forktip Casting company believes that the third is the quality of raw materials used for casting. The quality of materials such as metal furnace charge, refractory material, fuel, flux, modifier, casting sand, molding sand binder, and coating is not up to standard, which will cause defects such as pores, pinholes, slag inclusions, and sand sticking in castings, which will affect the appearance quality of castings and internal quality, the casting will be scrapped in severe cases.
The fourth is process operation. China Forktip Casting company should formulate reasonable process operation rules, improve the technical level of workers, and make the process rules be implemented correctly.
