Metal Injection Molding 9-11-1 Snow Tire Tungsten Steel Anti-skid Studs 11#

The possible defects of PIM products are basically formed in the injection molding step, such as cracks, pores, welds, delamination, separation of powder and binder, etc., but these defects are often not found until the stress generated during injection is released after degreasing and sintering. Therefore, the control of injection molding process is very critical to improving the yield rate of tungsten alloy powder products and the utilization rate of tungsten alloy powder materials. The purpose of injection molding is to obtain a defect-free molded blank of the desired shape. Injection defects cannot be eliminated in subsequent processes, so this step must be strictly controlled. In industrially developed countries, ultrasonic testing technology is gradually being used to reflect the internal defects of injection molded blanks and advanced experimental methods are being used to eliminate them. Although the causes of injection defects have been identified, in most cases, defect control in the injection stage is still mainly based on experience. With the advancement of science and technology, the future development trend is to use computers to simulate the injection molding process of feeding, and to link it with feeding performance, etc., to optimize injection condition parameters.
