The Auto Parts Casting usually have some special requirements. For example, the static balancing and dynamic balancing are required for the impellers, while almost all the Auto Parts Casting parts should have very strong ability of anti-rust and should be against the high pressure. But at RMC, we have rich experienced in reaching these requirements by improving the structure design, choosing the right metals and making the tight tolerances. And also all the related inspections above could be made at our workshop.
