EGR Intake Chamber - Stainless Steel Precision Castings from Reliable China Suppliers and Factory
Product description
Product features
-
1. thin-walled, complex structure, easy to produce deformation in the casting process
-
2. the product has a sealing requirement, for casting defects control requirements are high
Figure 2 shows the flange surface of the parts, this surface is connected to the external air intake sealing flange surface, so there are flatness and roughness requirements; face of the notch is to prevent the installation of interference with the choice of avoiding the air.
Figure 3 shows the machining of the square port, the role of processing here is to meet the needs of the drawing tolerance ± 0.05mm, for brazing with the EGR shell fit, the size of the conformity determines the pass rate of brazing;
Figure 4 shows the waist-shaped mounting holes, here the role of the EGR cooler and the body of the role of the connection, the waist-shaped holes have the advantage of improving the adjustment space during installation;
