Powder metallurgy processing gear technology (refer to understanding)

The basic process of powder metallurgy processing gears is described below for reference.

1. Flour milling

Commonly used powdering methods include oxide reduction method and mechanical method.

It is the process of making raw materials into powder.

2. Mixing

There are three types: dry type, semi-dry type and wet type, which are used for different requirements.

It is the process of mixing various required powders in a certain proportion and homogenizing them to make the green powder.

3. Forming

The molding method is basically divided into pressure molding and pressureless molding.Compression molding is most widely used in compression molding.

It is the process of putting a uniformly mixed mixture into a press mold and pressing it into a parison with a certain shape, size and density.

4. Sintering

Sintering is divided into unit sintering and multi-component sintering, which is a key process in powder metallurgy technology.

The formed compact is sintered to obtain the required final physical and mechanical properties.

In addition to ordinary sintering, there are also special sintering processes such as loose sintering, immersion method, and hot pressing method.

5. Treatment after sintering

According to different product requirements, various methods such as finishing, oil immersion, machining, heat treatment and electroplating can be adopted.

In addition, in recent years, some new processes such as rolling and forging have also been applied to the processing of powder metallurgy materials after sintering, and have achieved ideal results.

The above is powder metallurgy processinggearThe basic process description of the process, welcome to add if there are any deficiencies.
