![]() The team at RMC will get back to you soon. ![]() To learn more about what we can do for you, just feel free to contact us directly. Contact our sales engineers of export professional Custom China Investment Casting Foundry supplier in Following Stats Sukhbaatar, Sayin Shanda, Dalanzadgad. Our dimensional inspection can be the one or full of the following method. The inspection results are all recorded well, and represented on the paper as well as in the data-base by computer. After the steel casting partsbeing machined or finished the surface finish, three pieces or more pieces according to the requirements will be pick out at random, and dimensional inspection will be implemented. Process audit will be implemented during the whole machining process of the steel castings according to the drawings and machining process card. ![]() The mechanical properties testing must be done strictly by the professional equipment as in the following: The non destructive testing can be processed to check the defects and inner structure of the steel castings. The Spectrometer and Carbon Sulfur analyzer are the main equipment for the chemical composition testing. The specimens being tested also are kept well for at least two years for tracking using. Heat numbers including the time and temperature can be made to keep the traceability of the custom castings. Simulation programs tools (CAD, Solidworks, PreCast) are used to make the engineering works of casting more predictable to eliminate the defects and improve the stability before real manufacturing.Ĭhemical composition analysis to the castings is required. Specimen will be taken and tested both pre-pouring and post-pouring to control the chemical composition within the specification, and the results must be doubled checked again by the third inspectors. Chevrolet Cylinder Heads 3782461, 2.06/1.6 Corvette Fuelie Cast Iron Machined Date: H45 Auxiliary Casting Numbers: GM9 Double Hump Finish: Machined Machined for Valves: 2.06/1.6 Features: Screw-In Rocker Studs Chevy SB 400 Steam Holes Pushrod guide plates (Manley) Valve guides Condition: One cracked outer ear Slight surface rust after sandblast. Product quality documentations and inspection reports must be provided by the supplier, and inspection will be implemented strictly during the materials’ arrival. Incoming raw material were kept in control strictly, because we believe raw material in good quality is the foundation of the high quality of the castings and finished products.Īll the raw material like wax, water glass, aluminium, iron, steel, chromium etc are bought from the certificated manufacturers stably. RMC's foundry achieved certification to ISO 9001-2015. With help of the quality management systems, we standardized our production process, and made the quality stable while reducing the costs.
