EGR Gas Chamber - Precision Stainless Steel Casting from China Suppliers & Factory for Auto Exhaust Treatment
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.
