China EGR Gas Chamber - Stainless Steel Precision Casting Suppliers & Factory for Automobile Exhaust Systems
Product Description
This is a part used in China's famous diesel engine factory, the engine exhaust system - EGR cooler in the parts, the name is called gas 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;
Product Features
Thin-walled, complex structure, easy to produce deformation in the casting process
The product has a sealing requirement, for casting defects in the control of higher requirements
There are high positional requirements between the processing surface, especially the EGR valve mounting surface is very high precision, so the development of high requirements for the development of processing equipment
The structure of the product is called complex, and then the pre-development, the sealing test does not pass, resulting in a high rate of scrap, through the efforts of our team, and finally overcome the casting defects, reduce the leakage rate and achieve mass production;

Our company has a strong technology development team, with the ability to develop a variety of shaped parts in the field of precision casting, and provide integrated services from blank to machining; strive for excellence, to provide customers with efficient, high-quality products and services has always been our adhering to the concept.
Frequently Asked Questions
What is the application of this gas chamber part?
This gas chamber is used in the engine exhaust system (specifically the EGR cooler) for a famous diesel engine factory in China.
What material is used to manufacture the gas chamber?
It is manufactured using high-quality stainless steel 304 material, which offers excellent high temperature resistance and corrosion resistance.
What are the primary manufacturing challenges for this product?
The main challenges include its thin-walled and complex structure which easily deforms during casting, strict sealing requirements to prevent defects, and high positional precision requirements on the processing surfaces (especially the EGR valve mounting surface).
How did your team resolve the early-stage sealing issues?
During pre-development, the complex structure caused failed sealing tests and high scrap rates. Through dedicated engineering efforts, our team successfully overcame the casting defects, reduced the leakage rate, and achieved reliable mass production.
When did mass production begin and what is the current supply capacity?
Mass production started in 2017. The product is in a stable supply state with an annual supply volume exceeding 20,000 units (2W+).
