There is a large demand for metal parts in auto industry and there are tight and contradictory requirements for auto parts. However, powder metallurgy has fixed it. On the one hand, powder metallurgy results in high accuracy, great surface roughness, good mechanical properties, and especially amazing stability. On the other hand, powder metallurgy is right for mass-production with low cost and high efficiency.
In auto industry, there are serious competitions between auto parts manufacturers. And each part must be precise machined, which will raise the process complexity and cost much. The accuracy is satisfied, but stability and delivery time are not. In this circumstance, powder metallurgy has developed and shown its amazing superiorities in manufacturing auto parts, such as high purity, good adaptation, perfect uniformity and satisfied mechanical properties.
Sintering could make auto parts with high mechanical strength and tensile strength for cars, and the demand for these has never stopped rising.
