Affect the quality of the casting machine casting factors

The first is the casting process design. Design, in addition to the working conditions and metal materials to determine the performance of the casting geometry, size, but also from the perspective of casting alloys and casting process characteristics to consider the design of the rationality, that the obvious size effect and solidification, shrinkage , Stress and other issues in order to avoid or reduce the composition of castings segregation, deformation, cracking and other defects.

The second is to have a reasonable casting process. That is based on the casting structure, weight and size, casting alloy properties and production conditions, select the appropriate parting surface and shape, core method, reasonable set of casting tendons, chilled iron, riser and pouring system. To ensure access to high-quality castings.

The third is the quality of raw materials for casting. The quality of castables, refractories, fuels, fluxes, modifiers, as well as the quality of foundry sand, sand binders, paints and other materials can cause defects such as porosity, pinholes, slag inclusions, and sticking sand that affect the quality of the castings And the internal quality, serious casting will be scrapped.

The fourth is the process operation, to develop a reasonable process operating procedures, improve the technical level of workers, so that the correct implementation of the process rules.

Wear resistance and dimensional stability of machine tool castings, a direct impact on the accuracy of machine tools to maintain life.
