As a metal part forming process for manufacturing automotive parts, powder metallurgy PM technology has always been valued by the global auto industry. Iron-based powder metallurgy parts have reached 1.75% of automobiles produced in the United States. At present, there are about 20,000 parts in a car. According to preliminary statistics, there are 230 powder metallurgy parts used in cars, with a total of about 750 parts. That is to say, according to the number of parts used in automobiles, powder metallurgy parts have accounted for about 3.75%. This shows the use of powder metallurgy parts in automobiles, basically small parts. Most of the small auto parts are produced by casting, forging, welding, and cutting, while powder metallurgy parts can replace processed parts, forging, cutting parts and steel accurate processing parts, which can save a lot of materials, energy, and production costs. , and even reduce the weight of the parts, which is beneficial to the lightweight of the car and the reduction of environmental pollution.
In 2005, the average amount of powder metallurgy parts for each car produced by GM in the United States was 20.5KG, 21KG for FORD, 18.6KG for DAIMLER CHRYSLER, 14.5KG for Toyota, 16.8KG for Honda, and 16.8KG for Nissan. 14.1kg
Powder metallurgy parts used by Ford Motor Company in automobiles:
1. For engine applications, powder metallurgy parts mainly include oil pump rotors and gears, crankshaft sprockets and rocker arm joint shafts
2. The application of automatic transmission, the three automatic transmissions C6, FMX and C4 produced by Ford all use powder metallurgy parts.
3. The chassis uses powder metallurgy parts, and the ball joint bearings can only be produced by powder metallurgy
4. Powder metallurgy parts are used in power steering devices.
5. Application of powder metallurgy parts in windshield wiper motor
Powder metallurgy metal forming process, especially suitable for high-volume production industries such as automobiles. The production cost of powder metallurgy parts depends on the cost of molds and equipment. Powder metallurgy has high material utilization and lowest energy consumption. The material density of powder metallurgy parts is controllable. Powder metallurgy process can use powder metallurgy process to manufacture parts with special properties from special materials according to the use function of the parts. The powder metallurgy process can produce very complex auto parts.
