Injection molding has the advantages of high utilization ratio, good surface finish and low production cost. It is especially suitable for mass production of hard alloy parts with small size and complex shape.

Common degreasing defects include debinding deformation, degreasing crack, bubbling, warping, delamination and decarburization. Bubble, warping and delamination are common defects in thermal debinding process. It is one of the core of cemented carbide production control to formulate corresponding defect prevention and solution measures according to specific defects.
