EGR Water Chamber - Precision Castings from China Suppliers & Factory - Stainless Steel 304 for Exhaust Gas Treatment
Product Description
Product Features
1. Thin-walled, complex structure, easy to produce deformation in the casting process.
2. The product has a sealing requirements, for casting defects in the control of higher requirements.
Figure 2 position, for the position of the external water pipe, the use of O-ring radial seal, so for the processing precision requirements, high.
Figure 3 position, for the welding surface and EGR shell welding, in order to ensure that the brazing pass rate, so for the processing of the flatness has certain requirements;
Figure 4 position for the external small water pipe, due to the use of brazed sealing between the parts, the precision requirements are higher.
Frequently Asked Questions (FAQ)
The EGR cooler water chamber is made of stainless steel 304 material. This material provides excellent high temperature resistance and corrosion resistance, making it ideal for automotive and industrial applications.
Besides being used in automobile exhaust systems (EGR coolers), this precision casting part is widely used in food machinery, valve bodies, pumps, and other related industrial fields.
The thin-walled and complex structure makes it easy to deform during the casting process. Additionally, because the product must meet strict sealing requirements, there are very high demands on controlling casting defects.
We achieve reliable sealing through high-precision processing. Specifically, we use an O-ring radial seal for the external water pipe position, ensure flatness for the welding surface with the EGR shell to maximize the brazing pass rate, and maintain tight tolerances for the brazed sealing of the external small water pipe.
We optimized the appearance of the product in collaboration with our customer to avoid structural hot joints. Mass production began in 2018, and we have continuously supplied approximately 50,000 pieces per year since then.
Yes, we provide integrated services from precision casting to machining. Our strong technical development team is capable of developing a wide variety of shaped parts to deliver efficient, high-quality products and services.
