by:XEX     2020-11-12
Precision casting is a less cutting or no cutting casting process, is an excellent technology in foundry industry, its application is very extensive. The general stainless steel precision casting structure on the performance of general how to design? Precision casting performance structure design principle is as follows: 1, the reasonable wall thickness. Under the condition of meet the small castings promised to wall thickness, which can guarantee the molten metal has good mobility, can avoid to produce casting defects caused by shrinkage is too big. 2, uniform wall thickness. Refers to the various parts of the wall thickness uniform cooling rate. Thin wall partition, all round the walls should be thick. 3, transition connection. Structure of the rounded: avoid hot forming; To improve the stress distribution; Avoid the damage of sand mold and sand holes. 4, the big plane tilt. Objective: to use padding and exhaust. 5, free shrinkage. Objective: good decrease caused by shrinkage stress of stress cracking and deformation. 6, reduce the deformation. ( With heat treatment) Symmetrical structure, adding stiffening ribs. We are all in the structural design of the performance of stainless steel precision casting, can operate according to the above design principles, friends in need of stainless steel precision casting, dongguan precision casting can contact us. https://www. xexfoundry。 com/
