Cover mold mainly in the production of cement cover mold mainly trench cover mold, conventional production of cement cover mainly plastic cover mold mainly due to cement trench cover is often crushed, roads were damaged, so the use of steel grating cover mold making sales immediately set off a storm, except for the use of cover mold of road safety are guaranteed, is also reflected in the construction of the advances in technology, beautiful appearance, toughness optimum drainage, anti-theft security, high intensity In terminals, airports and other large span heavy load environment it has been the perfect embodiment. There are mostly mold production process mainly in the following six stages. The first is the cover mold programs identify, analyze product parts structure, dimensional accuracy, surface quality requirements and molding process. Then there is the mold design plastic trench cover mold, molded parts modeling, structural design. Then is the production preparation of the mold, molded parts material, blanks and other processing modules. Standard parts and components with the purchase. According to design, the preparation of the code consisting of processing procedures, as well as cutting tools, tooling and so on. Curb side drainage molding parts processing, according to the process planning, conduct molding, machining holes, or the use of EDM, grinding and other traditional molding technology for processing, and the corresponding heat treatment process.
