Product History
Frequently Asked Questions
It is a gas chamber used in the EGR cooler of an engine exhaust system, specifically designed for a famous diesel engine factory in China.
It is made of Stainless Steel 304 (SS304), which provides excellent high temperature resistance and corrosion resistance.
The main challenges included casting deformation due to its thin-walled and complex structure, strict sealing requirements to control defects, and high positional precision requirements for the EGR valve mounting surface.
Through dedicated team efforts, we overcame casting defects and resolved sealing test failures, which successfully reduced the leakage rate and enabled stable mass production.
Mass production began in 2017. The product is in a stable supply phase with an annual delivery volume exceeding 20,000 units (2W+).
We provide fully integrated services from blank casting to final precision machining, with strong capabilities in developing custom-shaped precision casting parts for automobiles, food machinery, valve bodies, and pumps.
