What are the metal molding challenges in your industry

MIM powder metallurgy technology is a kind of mechanical structure parts manufacturing technology which can manufacture complex shape parts, save material, energy and labor. It has been recognized as a green and sustainable manufacturing technology in the industry. With the introduction of national energy conservation, emission reduction, automobile safety and environmental protection policies and regulations, as well as the research and development of new energy vehicles, environmental protection products will become the future development of the key trend, which brings new challenges to MIM powder metallurgy products, but also brings great development opportunities.

Compared with the traditional process, MIM powder metallurgy technology has the advantages of high raw material utilization rate (up to 95%), low manufacturing cost, good material integration, near-net forming, high precision and stability of products, and so on. At the same time, MIM powder metallurgy is not only an important process for manufacturing new and high materials, but also the main method sometimes. At the same time, it is also an advanced metal forming technology for manufacturing complex and high-precision metal parts. Therefore, it is favored by people.

Challenges of MIM Industry:

1. Product size. At present, most MIM factories can realize the maximum product size of 200mm in length and 500g in weight. New die design techniques and new injection molding techniques are needed to overcome larger sizes.

2. Material diversity. At present, the main materials used in MIM industry are iron powder and stainless steel powder (316,304,420,440, 17-4pH). Copper materials are rarely used, and only a few MIM factories develop copper products, resulting in high sintering cost. Tungsten carbide, titanium alloy and so on are still in the development stage, if the development is successful, the application of MIM industry will be very broad.
