What is the powder metallurgy process like?

Powder metallurgy process is a new type of net near-forming technology, through the melting, heating, injection, pressing metal powder for the required mold molding, for some difficult to process, refractory metals, high alloying and other special materials, the traditional processing methods are difficult to cope with, and powder metallurgy has become the main method of processing and production, especially in the high-precision gears and automotive spare parts have been a large number of applications, the next give Next, we will talk about the basic process flow of powder metallurgy technology is how, so that you have a deeper knowledge and understanding of powder metallurgy.

One: the basic process flow of powder metallurgy

Step 1: raw material preparation into metal powder

One step of the preparation of raw materials into metal powder by oxide reduction and mechanical methods.

Step 2: Make billet powder

According to the requirements of different products, use wet or dry, semi-dry according to a certain proportion of the powder is mixed evenly, made of billet powder, the proportion of powder must be well controlled.

Step 3: Mold Forming

The mixed blank powder is loaded into the corresponding mold of powder metallurgy, and then formed into the desired shape by pressure molding or pressureless molding.

Step 4: Sintering of Powder Metallurgy Model Products

The molded model is sintered by multifunctional sintering or unit sintering, and the physical and mechanical properties of the final part can be formed as required, and the Powder Metallurgy sintering process is the most important step in the whole process, and it is the decisive process for the good or bad performance of the products.

Step 5: sintering follow-up details

For products with high precision requirements through the sintering process also need to be followed by finishing, oil immersion, plating, or a small amount of machining, heat treatment, and other details of the treatment, so that the stability and hardness of the product better.

Two: powder metallurgy process is used in what areas?

1: Automotive field

Automotive field of gears, engine rotors, automotive tailgate, automotive wiper and other locations of the powder metallurgy process spare parts.

2: Digital electronics and home appliances

Smart phones, laptops, smart wear, home appliances and other spare parts of the powder metallurgy process applications.

3: the field of hardware tools

Locks, locks, power tools, hardware tools spare parts are used in powder metallurgy molding technology process.

4: communication field

Base station communication gear box, antenna and other spare parts are using powder metallurgy process.

5: medical equipment

Medical equipment for spare parts requirements are relatively high, powder metallurgy close molding technology is very consistent with the application of medical equipment spare parts, higher precision, the production of cleaner and more hygienic products.
