EGR Intake Chamber - Stainless Steel Precision Castings from China Suppliers & Factory for Automobile Exhaust Systems
Product Description
This is a part used in the automobile exhaust system-EGR cooler, the name is intake 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 a sealing requirement, for casting defects control requirements are high.
- Figure 2 (Flange Surface): This surface is connected to the external air intake sealing flange surface, so there are flatness and roughness requirements; the face of the notch prevents installation interference with the choice of avoiding the air.
- Figure 3 (Square Port Machining): The machining here meets drawing tolerances of ± 0.05mm. This precise fit with the EGR shell determines the pass rate of brazing.
- Figure 4 (Waist-shaped Mounting Holes): Connects the EGR cooler to the body, offering the advantage of improved adjustment space during installation.
- Developed in mid-2020, with mass production realized in 2021. It is currently in a stable supply state with an annual output of 100,000 pieces.
- Our company has a strong technical development team with the ability to develop a variety of shaped parts in the precision casting field. We strive for excellence to provide customers with efficient, high-quality products and services.
Frequently Asked Questions
What material is the intake chamber made of, and what are its benefits?
The intake chamber is made of premium stainless steel 304 material. It offers outstanding high-temperature resistance and excellent corrosion resistance, making it highly durable for automotive exhaust systems.
What are the primary applications for this precision casting component?
This component is widely used in automotive exhaust systems (specifically EGR coolers), food machinery, valve bodies, pumps, and other fields requiring precision-cast components.
How do you control quality for the thin-walled structure and sealing requirements?
Because thin-walled structures are prone to deformation during casting, we implement strict defect control processes and precise machining tolerances to meet the critical sealing and flatness requirements.
What is the tolerance of the square port, and why is it important?
The square port is machined to a precise tolerance of ± 0.05mm. This strict compliance ensures a tight fit with the EGR shell, directly determining the quality and pass rate of the final brazing process.
What is your current production capacity for this intake chamber?
Following development in 2020 and mass production in 2021, we maintain a stable supply chain with an annual capacity of 100,000 pieces to support our customers' needs.
