There are a lot of PIM auto parts in production, many of the early successful products obsolete, no longer in production. The first successful products have a locking mechanism, transmission synchronizer, airbag sensor, the inner handle, turn signal control unit and engine oxygen sensor. However, only a few companies have enough experience in the production of automobile field orders related to pick. For example, it has been shown that some engine tappet parts required productivity is 300000 pieces per day, which far exceeds the capacity of even some large companies. In 2000, through the PIM method for the production of auto parts worth nearly $50000000 (Japan accounted for 40%, American accounted for 35%, Germany 25%). This rapid growth in the past few years. Many of these parts are heat-treated high strength low alloy steel, in order to achieve the best mechanical properties.

In the fuel system, there are several parts can be made of PIM, is used in high hardness, abrasion resistance material. These parts are needed to achieve the required surface quality by grinding after sintering. Similarly, the new spark plug design using PIM technology, which makes the wall thickness is thinner, more complex, can be integrated diagnostic sensor. Research of considerable input to the manufacturing of high temperature gas turbine components, such as turbochargers, a fixing sheet, rotor and disc, catheter and a protective cover of ceramic gas turbine parts, using the PIM silicon carbide parts of the engine, the prototype can work up under the temperature of 1200 DEG C, rotate speed is 100000 RPM. A similar example parts also adopts the silicon nitride Application of many automotive field are those in the appropriate location, complex shape, it is difficult to use other competitive process to manufacture parts, such as the ignition key parts box sensor fixing seat and a magnetic sensor.

Because PIM for hard material parts and low cost of production, several manufacturers are verified by PIM manufacturing wear-resistant parts. Most of the high temperature parts in high-speed operation, especially in the strong corrosion or wear environment. An early example is silicon nitride ceramics, but recently turned to the metal alloy so that with the increase of production cost reduction. Similar interest is the engine ceramic valve is made of PIM silicon nitride. A group of inlet valve presentation software have tried more than 260000 km, the report shows the performance of the improved fuel consumption. Recent attention to wear parts, hard alloy in automobile engine.

In order to further to the auto market, the need of tensile strength after heat treatment of steel structure is up to 1800MPa, elongation of at least 3%, after heat treatment, the hardness reaches 50HRC, the impact toughness than 100J8/ cm, fatigue strength reaches 500MPa. for transmission system parts, rolling contact fatigue strength must be more than 2000MPa. so the new alloy steels are constantly improvement to meet the performance requirements,such as Fe-1Cr-0.2Mo-0.8Mn, carbon and silicon content from the need to control the hardening effect. Higher alloy degree material (mass fraction of up to 8% Cr, 2% Mo and 1% Ni) is related to a desired extreme stress and wear applications. PIM stainless steel, especially the heat treatment of martensite and the precipitation hardening alloy,can be directly used for automobile parts. Some of the copper alloy are also considered as thermal management system in automobile interior.
Today, a large number of PIM auto parts has been put into mass production, used in security systems, engine management, fuel injection, interior decoration and other in mechanical, magnetic and electrical aspects of application. The car will become the largest application field of PIM.
