EGR Water Chamber - Stainless Steel Precision Castings from China Suppliers and Factory
Product Description
This is a part used in the automobile exhaust system-EGR cooler, the name is water 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 so on.
Product Features
- Thin-walled, complex structure, easy to produce deformation in the casting process.
- The product has sealing requirements, requiring higher control of casting defects.
- Figure 2 position: For the position of the external water pipe, the use of O-ring radial seal requires high processing precision.
- Figure 3 position: For the welding surface and EGR shell welding, in order to ensure the brazing pass rate, the flatness processing 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.
This type of structure seems simple, but in the development process, it is easy to produce structural hot joints. Through customer communication, we obtained customer consent to optimize the appearance of the product. Mass production began in 2018, and we have continued to supply about 50,000 pieces per year so far.
Our company has a strong technical development team with the ability to develop a variety of shaped parts in the field of precision casting. We provide integrated services from casting to machining, striving for excellence to provide customers with efficient, high-quality products and services as our adhering concept.
Frequently Asked Questions
QWhat is this product and where is it applied?
This product is a water chamber used in the automobile exhaust system (specifically the EGR cooler). It is also widely used in precision casting parts for food machinery, valve bodies, pumps, and other industries.
QWhat material is used for the water chamber?
It is made of high-quality stainless steel 304 material, which provides excellent high temperature resistance and corrosion resistance.
QWhat are the technical challenges during the casting process?
Because the part has a thin-walled and complex structure, it is prone to deformation and structural hot joints during casting. Therefore, control of casting defects and sealing requirements is highly demanding.
QHow do you ensure the precision and sealing quality of the connections?
For the external water pipe, we use an O-ring radial seal that demands high processing precision. For the welding surface and EGR shell welding, we control the flatness to ensure a high brazing pass rate. The external small water pipe also utilizes high-precision brazed sealing.
QWhat is your production capacity for this specific EGR cooler water chamber?
We optimized the product design in collaboration with our customer and started mass production in 2018. We have continuously supplied approximately 50,000 pieces per year since then.
QDo you offer customization and machining services?
Yes, we have a strong technical development team capable of developing various shaped parts in precision casting. We provide integrated services covering the entire process from casting to final machining.
