This classification mainly includes the aluminum alloy die casting Motor parts using in Auto area,the raw material is aluminum alloy.
In the die casting process,higher specific pressure is required, so that higher filling speed can be obtained.which is beneficial for alloy to overcome mold filling resistance.and effectively fill each part of the cavity.The Casting General Tolerance is Grade GB-CT4.

The valve flange seal connection between the contact parts according to the design requirements placed gasket, relying on the bolt to produce pre-tightening force to achieve a sufficient pressure, to prevent media leakage to the outside. Gasket materials and structures are: rubber gasket, asbestos rubber gasket, graphite gasket, stainless steel and graphite wound gasket, corrugated pipe and metal gasket. Gasket seal is a mandatory seal. Common flange leaks are the following species: a. Interface leaks - leaks between the seal and the face of the flange. The main reason: the gasket preload is not enough ----- Treatment: Appropriate to increase the preload; Flange sealing surface does not match the requirements of roughness - Remedy: Flange surface is uneven or horizontal scratches - Remedy: Rework; cold and hot deformation and mechanical vibration, etc. --- Remedy: improve the environment or material selection; flange connection bolt deformation elongation ---- treatment: materials and can not exceed the allowable torque; seal Long-term use of gasket plastic deformation - Treatment: replacement; gasket aging, cracking and deterioration --- Treatment: replacement. b. Penetration Leakage - - The media creates a leak through the gasket material gap under pressure. The main reason: with the gasket material; media pressure; media temperature; gasket aging, cracking and deterioration. c. Leakage - Leakage due to over-compression of the gasket due to mounting quality or insufficient seal pressure. Main reasons: the installation of gasket bias, the local seal than the lack of pressure or preload is too large, loss of resilience; flange connection bolts elastic uneven; two flange concentricity (centerline offset) skew ; Gasket selection wrong or not according to working conditions, the correct selection of gasket material and type; interface leakage and damage leakage will significantly increase over time, the leakage of leakage and the relationship between the time is not obvious.
