Application of MIM Parts of Metal Injection Molding in Automobile Industry

The automobile industry has become the main application field of MIM parts for metal injection molding, such as the complicated parts used in engines, gearboxes, turbochargers, locking mechanisms, steering systems and electronic systems, which are numerous.

(1) Rocker arm of BMW engine

One is the rocker arm that rotates with the roller. This is a rocker arm made of low alloy steel that controls the variable valve timing travel of the engine. It is characterized by its hollow structure and light weight, which is difficult to make by other methods.

(2) Gear lever

This is a large amount of metal injection molding MIM parts, used for passenger car manual transmission.

The production process of this part is: injection molding, sintering, hardening treatment and shaft assembly.

The material used is Fe2Ni, and the parts shall be carburized and quenched after sintering.

(3) TURBOCHARGER BLADE

This kind of metal injection molding MIM variable cross-section nozzle blade used in automobile diesel engine turbocharger has a large output. This part can meet the strict dimensional tolerance requirements, and the blade profile can reach the accuracy of ± 0.015mm by cutting.

The blade is produced by a special mold, which has excellent sliding function when opened, and can reduce deformation when it is pulled out. MIM production of metal injection molding can reduce the production cost by 20%.

Now, the most advanced is the production of MIM superalloy parts by metal injection molding, and its market share has been increasing. For example, Inconel 713 materials have ready-made MIM injection materials for metal injection molding.

The MIM production process of metal injection molding uses fine and dispersed powder, so the delivered parts have a very uniform microstructure, which greatly improves the microstructure of precision casting products.

Zhongwei Precision is dedicated to the development and production of various non-standard precision complex structural hardware. In the current competitive and uncertain environment, our company will continue to introduce new technologies, new techniques and new concepts to improve our products to meet the needs of all sectors. We will further implement the concept of quality and service, pursue a more perfect realm to promote the pace of internationalization and give back to the public.
