Powder metallurgy parts have gradually been accepted by mass production in the automotive industry.

In recent years, due to the excessive use of high-carbon energy by humans, extreme climates have occurred frequently, causing serious disasters to human life. In order to achieve the goal of harmonious coexistence between man and nature, we must change the existing way of life, save energy, reduce CO2 emissions, protect the ecology, and welcome the arrival of the low-carbon era.

As a small, non-cut metal parts manufacturing process, powder metallurgy is increasingly used in the automotive industry. In a car, up to 130 kinds of parts can be produced by powder metallurgy. In foreign countries, powder metallurgy production suppliers are mainly for the automotive industry, 90% of its output value comes from the automotive industry; but domestic automotive-related enterprises The metallurgical process is still relatively unfamiliar.

Powder metallurgy is a process technology for producing metal materials, composites, and various types of articles by forming or sintering metal or metal powder (or a mixture of metal powder and non-metal powder). Powder metallurgy generally undergoes three major processes of powder mixing, forming and sintering. Powder metallurgy is similar to the production of ceramics, so a series of new powder metallurgy techniques can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a decisive role in the development of new materials.

Due to the existence of pores in powder metallurgy parts, general engineering and technical personnel have doubts about the strength of powder metallurgy materials, and it is considered that the strength of powder metallurgy materials is lower than that of steel. In fact, the strength of powder metallurgy parts has a series of standards that can fully meet the technical requirements of different automotive parts.

With the development of China's automobile industry, more and more metal parts can be produced by powder metallurgy process. Powder metallurgy has gradually accepted for mass production in the automotive industry due to its many advantages. The improvement of the energy saving and emission reduction requirements of the automotive industry has in turn promoted the development of the powder metallurgy industry. It is hoped that the powder metallurgy industry can contribute more to energy saving and emission reduction in China's automobile industry. It is also hoped that the green powder metallurgy process will bring us a blue sky.
