How do P/M manufacturers process P/M gears?

How do P/M manufacturers process P/M gears? Is there any difference between ordinary gear and powder metallurgy gear? Frequently, netizens who do not know powder metallurgy consult zhongwei to compile these gear related questions. It is true that many people do not know much about powder metallurgy processing technology. Here we are going to introduce you to Zhongwei Precision Powder Metallurgy Factory:

Powder metallurgy factory

1. What is powder metallurgy gear

As the name implies, P/M gears are gear parts in various fields. They are processed with P/M technology. P/M gears can reduce cutting or no cutting, reduce processing steps, reduce the waste of many raw materials, and make gears more precise. P/M gears have become the main application in various high-end automobile, ship, and motorcycle gears.

2. How are powder metallurgy gears processed?

1: Preparation of mixture

First, the powder raw materials are prepared, and then the powder is mixed to make raw materials.

2: Pressed powder forming

The raw metal powder is pressed into the desired style of powder metallurgy gear by powder metallurgy pressing equipment.

3: Sintering treatment

During the sintering process, the powder particles become metallurgical gears with certain porosity through a series of physical and chemical processes such as diffusion, recrystallization, fusion welding, combination, dissolution, etc. The sintered gears can be used.

4: Post processing procedures such as precision

Through the methods and steps of fine pressing, rolling, extrusion, quenching, oil immersion, etc., the powder metallurgy gear has higher precision, hardness, wear resistance and better performance.

Through the above introduction of Zhongwei, I believe you have roughly known how powder metallurgy manufacturers process powder metallurgy gears. In fact, the processing steps and processes of gears and other powder metallurgy parts are similar. If traditional machining and molding technologies are used, the steps and processes will be much more complex and the cost will be higher.
