Rotate the retaining seat manufacturers tell you the powder metallurgy part forming process: feed preparation, injection molding, degreasing and sintering.

1. Feeding preparation is a more critical step, because the defects introduced by this step cannot be eliminated in the subsequent process. Among them, the binder, as the core part of the feeding, directly affects the uniformity and formability of the feeding, and then affects the progress of the subsequent process and the performance of the product.
2. The forming process of powder metallurgy parts can be simply described as: Rotate the retaining seat manufacturer tells you to first heat the feed to the melting temperature, then pressurize the melt to enter the mold cavity, and cool it in the mold cavity to form.
3. Since the emergence of this technology, with the difference of the binder system, a variety of process paths have been formed, and the degreasing methods have also been varied. Rotate the retaining seat manufacturers tell you that the degreasing time has been shortened from a few days to a few hours now. From the degreasing step, all degreasing methods can be roughly divided into two categories: one is the two-step degreasing method. The two-step degreasing method includes solvent degreasing + thermal degreasing, siphon degreasing-thermal degreasing, etc.
4. Sintering is the next step in the process, and sintering eliminates the pores between the powder particles. Make the product reach full densification or close to full densification. The Rotate the retaining seat manufacturer tells you that due to the use of a large amount of binder in the powder metallurgy part molding technology, the shrinkage during sintering is very large, so there is a problem of deformation control and dimensional accuracy control.
