MATECH policy is that none of these products will be sold to 3rd parties without written consent of the customers to whom the tooling, design and specifications belong.Production ProgressMold Design: For Low pressure casting/Gravity casting, the mold is made of metal materials. In this process, we asked our engineers to make the mold size slightly larger than the finished product, and the difference is called the shrinkage allowance. The purpose of this is to melt the metal into the mold to ensure that the molten metal solidifies and shrinks, thereby preventing voids in the casting process.Core Making:The core is formed by casting resin sand into a mold to form a casting of the inner surface. Therefore, the gap between the core and the mold eventually becomes a casting.Casting Producing: A mold is required during the smelting process. Molding typically involves the support frame of the mold, which is pulled out to separate during the casting process, where the previously placed core melts in the mold and then closes the die opening.Cleaning & Machining: The purpose of cleaning is to remove sand, sand and excess metal in the casting. Welding, sand removal can improve the appearanceof the casting surface by burning the sand and the scale is removed to improve the appearance of the surface of the casting.Excess metal and other risers are removed. A step further by welding and grinding. Some castings are subject to special post-processing requirements such as heat treatment, shaping, anti-rust treatment, roughing, etc.Finally, Checking the defects and comprehensive quality finishing, before processing, and then re-processing, according to the requirements of different customers, we can do heat treatment, surface treatment, additional inspection and so on.Technical Support: Shanghai Matech is professional at independent development and design. Our engineers are skilled at AUTO CAD, PRO ENGINEER, SOLID WORKS and other 2D & 3D softwares. We are able to design, develop,produce and deliver your PO according to your drawings, samples or just an idea. Dural control of standard products and OEM products.
