Using silicone molds and polyurethane (PU) resins, it is possible to get very close to production-quality parts with vacuum casting. The tooling is generally made from silicone, which is very cheap compared with a steel injection mold tool. A range of materials are available and it is possible to do over molded parts, as well. Vacuum casting is only really competitive for smaller production runs a...

Since mechanical polishing is mainly completed manually, polishing technology is still the main reason affecting the quality of polishing.In addition, it is also related to mold material, surface condition before polishing, heat treatment process and so on. High quality steel is the prerequisite to obtain good polishing quality, if the surface hardness of steel is uneven or there are differences i...

Mold Definition and Classification Mold is called “Mother of Industry”. It is a processing tool that processes raw materials and gives raw materials a complete configuration and precise size. It is mainly used for efficient and high-volume production of related parts in industrial products. The development of the mold industry has always been valued by the state. According to the National Developm...

Forgings  Compared with forgings, die casting can be more complex in shape and have shapes not forgeable, can have thinner sections, be held to closer dimensions, and have coring not feasible in forging. Plastic Injection moldings  Compared with plastic injection moldings, die casting are stronger, stiffer, more stable dimensionally, more heat resistant, and are far superior to plastics ...

Die casting mold is a method of casting liquid die stamping, a process completed in a special die casting die-stamping machine.  Its basic process is as below:  First, the metal liquid filled into the mold cavity with low speed or high speed, the mold has a movable cavity surface,  Then it is stamped as the metal liquid cools,  Finally, not only eliminate the defects of the cav...
