At RMC Foundry, we adopt many alternative casting processes to cast the metals and alloys as per customer’s requirements or based on our development. Different metal and alloy is suitable to its best castings process considering the end-user’s requirements and cost effective. For example, the gray cast iron is usually suitable to be cast by sand casting process, while the stainless steel tend to be cast by lost wax investment casting.


There are many factors we should take in account when we choose the right casting methods, such as the castability of the materials, requirement of weight (Aluminium and Zinc alloys are much lighter than other alloys), mechanical properties and if any special required performance in wear resistance, corrosion resistance, damping...etc. If we choose the precision casting (usually refer to the investment casting), there will be less or no need for CNC machining, which could save the whole manufacturing cost substantially.


Thanks to our rich experience and the well-organized equipment, we have diverse choices of castings for different industries. What we specialize are mainly sand casting, investment casting, shell mold casting, lost foam casting, vacuum casting and CNC machining. Both OEM custom services and independent R&D are available at our factory. The professional engineering is our core competitiveness.


More than 100 kinds of metal and alloys are cast at our foundry. They are mainly range gray cast iron, ductile cast iron, malleable cast iron to carbon steel, alloy steel, stainless steel and aluminium and brass alloys. Therefore, from our service, you can both choose the right casting process and materials to meet your respect request. Many of our custom casting components are serving wide ranges of mechanical and industries partners from Europe, America, Asia, Australia and of course, in China.
