Cross Use of Stainless Steel Precision Casting and Rapid Prototyping Technology

Cross Use of Stainless Steel Precision Casting and Rapid Prototyping Technology

The cross-use of science and technology is mostly complementary. The design and mold manufacturing in the wax mold making process of stainless steel precision casting are more complicated and time-consuming, but rapid prototyping technology can make up for this shortcoming. Using rapid prototyping technology alone is a Because material restrictions cannot be implemented, in recent years, many use polymer technology to obtain the round shape of the casting, and then manufacture wax molds, which are used in stainless steel precision casting.

Process characteristics of stainless steel precision casting

Process characteristics of stainless steel precision casting

Stainless steel has higher mechanical properties than cast iron for precision casting, but not as good as cast iron. Due to the high melting point of stainless steel precision casting, the fluidity of molten steel is poor, the molten steel is easily oxidized, and the shrinkage is large. The linear shrinkage is about 1.8-2.5%, and the volume shrinkage rate is about 10-14%.
