This is a part used in the automobile exhaust system-EGR cooler, the name is called outlet chamber.
It is made of stainless steel 304 material, which has the advantages of high temperature resistance, corrosion resistance, etc. It is widely used in the field of precision casting parts for automobiles, food machinery, valve bodies, pumps and other precision casting parts.
1.Thin-walled, complex structure, easy to produce deformation in the casting process
2.Products with sealing requirements, for casting defects in the control of higher requirements
3.The processing surface (external sealing surface, mounting holes, cooler welding surface) between the existence of high positional requirements, so for the development of high requirements for the development of processing tooling
In the early development process, from time to time, the processing size is not allowed, the position of the eccentricity is serious, we through the increase of blank shaping, auxiliary inspection fixtures, processing and adjustment of tooling, and ultimately, on schedule to complete the development of the customer’s requirements of each development node;
The product was developed in the middle of 2020, and mass production was realized in 2021, and is now in a stable supply state, with an annual supply of 100,000 pieces;
Our company has a strong technical development team, with the ability to develop a variety of shaped parts in the field of precision casting, and provide integrated services from casting to machining; excellence, to provide customers with efficient, high-quality products and services has always been our adhering to the concept.
