Metal powder injection molding (Metal Injection Molding, MIM) is a kind of near-net molding process, that not only can get high density, good mechanical properties, and small surface roughness of the parts but also a large number of high-efficiency production of complex structural parts, generally do not need to continue to finish machining, the parts cost reduction, promote the development of automotive lightweight and reduce environmental pollution. MIM is the largest user of MIM in the automotive industry and thus has attracted the attention of the automotive industry.

The automobile manufacturing industry is the largest user of MIM, the most typical use is high temperature, high wear resistance engine parts and transmission parts! At present, MIM powder metallurgy injection molding automotive parts require high precision, high-quality control requirements for the batch process, domestic technology, and Europe and the United States compared to developed countries, there is still a certain gap, with the development and progress of the domestic metal injection molding in recent years, there are many domestic and foreign well-known automotive brands in the domestic manufacturers to purchase powder metallurgy parts, such as Dongmu new materials, Harber Metal Group, Dongguan HuaYan, Changzhou Precision Research.

MiM Technology Process in the Use of Automotive Components

With the progress of science and technology, the main direction of automobile development is energy saving, environmental protection, comfort, intelligence and lightweight, MIM automotive products in the automobile application prospect is huge.

Using MIM technology, tiny automotive parts can be designed as a whole or multiple components, using Harber Metal's MIM process of one-time injection molding, so that the parts meet the performance of the premise, to achieve the characteristics of miniature, integrated, low-cost, and so on. At the same time, parts can be manufactured with external grooving, external threads, cross holes, blind holes, reinforcing plates, grooves key pins, and other complex shapes.

(1) Automobile by the body, chassis, engine three major assembly components, and auto parts procurement costs account for more than 70% of the cost of the vehicle. In the advanced countries of the international automobile industry, the total output value of auto parts is 1.4 times that of the whole vehicle.

(2) With the rise of automobile production, the automobile industry's material saving, energy saving, emission reduction and reduction of production costs have undoubtedly become an important challenge for the automobile industry. Powder metallurgy is an energy-saving, environmentally friendly, material-saving metal processing manufacturing process, which undoubtedly plays an indispensable role in modern automobile manufacturing.

The Applications of MiM Technology in Automotive Parts Are:

  1. Typical engine PIM products - Automotive turbocharger components
  2. Engine PIM typical products - Intake and exhaust systems
  3. Body and chassis on the application of
