Automotive Piston Market Overview:
Global automotive piston market is expected to reach $15,705 million by 2022, growing at a CAGR of 4.8% from 2016 to 2022. Automotive piston is an engine component cylindrical in shape, which slides back and forth in the cylinder bore due to force produced by the expansion of gas during the combustion process. Piston system comprises piston, piston rings, and piston pin; this system transfers the generated force to crankshaft through connecting rod. So the piston is one of the most important part in this system.And with the development of the society, the pistons can be made with the following materials:
(1) Steel
(2) Aluminum
However, with the trend of Lightweight car, more and more manufacturers change Steel pistons to Aluminum pistons. At first, many manufactuers use carbide insert machining pistons, they can’t obtain good surface roughness, so most manufacturers begin to test PCD Inserts. With PCD Inserts machining pistons, not only can obtain good surface roughness, but also can improve the efficiency.
