What is powder metallurgy processing like?

What are the advantages?

Powder metallurgy processing is to take all kinds of metal powder as raw materials, and then after a series of pressing, injection, sintering, post-processing and other processes to make the final desired product parts processing technology, powder metallurgy can be a large number of complex metal products processing molding, has replaced the traditional molding processing methods in all major areas of the new generation of near-net molding technology, so that powder metallurgy processing is more popular.

I. Powder Metallurgy Processing Flow

1、Metal powder raw material preparation

The method of making metal raw material powder generally has physical and chemical method and mechanical method, and these two methods and extend a variety of methods, at present in the powder metallurgy industry is widely used or oxide reduction method and mechanical method of these two methods, these two methods of powder making effect and performance through continuous testing and experimentation is appropriate.

2、Basic molding

After the raw material metal powder preparation, through the pressurized molding or pressureless molding and other molding techniques will be pressed into the shape of the product through the mold powder, this step is called molding, the product will have a certain strength and hardness.

3、Sintering after molding

The molded product billet sent to the sintering furnace, in the sintering furnace in a closed protective environment, after a period of high temperature sintering, powder particles produced between metallurgical bonding, you can get the hardness, strength of the higher parts, if for some special performance requirements, you have to carry out some follow-up processing, if not, after sintering the parts can be used, the current good sintering furnace is the German or The good sintering furnace is German or Japanese sintering furnace equipment, Harber Metal powder with these two kinds of advanced equipment as well as domestic well-known material testing machine, salt spray testing machine, a variety of hardness testers and a variety of high-precision measurement gauges.

Second, the advantages of powder metallurgy processing

The emergence of powder metallurgy products for the development of modern society has brought about a very big role in promoting the development of various industrial fields, powder metallurgy products to play out its own strength, for example, in the rapid development of automobile production, powder metallurgy process to provide a variety of advanced accessories products, greatly improving the performance of the car.

Powder metallurgy is able to develop rapidly in today's market because it has many advantages, the traditional casting process has not been able to keep pace with the rapid development of today's social and industrial footsteps, so many areas of the parts and components used in the product needs to be manufactured through high-tech means.

The use of powder metallurgy process to produce all kinds of products, not only can make all kinds of products have professional performance, to meet the production of the use of powder metallurgy process at the same time, the production cost is lower, for enterprises to bring more benefits. The energy-saving and consumption-reducing characteristics of powder metallurgy also make a great contribution to the harmonious development of society.

1、Near net molding technology, the use of raw materials can be as high as 95%, reducing a large amount of material waste.

2, direct molding, can be less cutting or no cutting, also reduces the waste of raw materials, reducing production costs.

3、Powder metallurgy processing can also control the accuracy and density of parts, especially those porous materials.

4, the material group can be controlled, more complex composite materials are very suitable for the use of powder metallurgy processing.

5, like some ceramics, refractory metals, etc. can be prepared, which is the traditional processing technology can not do.

6, large quantities can be produced and processed, greatly improving production efficiency, reducing production costs, and molding with uniformity.
