About mold making suppliers

Moldmakers make metal molds for die casting and shaping the plastic, ceramic and composite materials people use in their daily lives. This position requires technical and mechanical skills, as well as long hours of factory work.

Mold making is critical to a variety of manufacturing processes; molds serve as blueprints from which many mass-produced products can be replicated. Manufacturing processes that rely on molds include:

Injection molding is one of the most popular manufacturing processes for thermoplastic, silicone or rubber parts. This is a cost-effective and extremely repeatable technique for producing high-quality parts for high-volume production. With this process, a developed mold is inserted into an injection molding machine, and heated thermoplastic or liquefied raw material is poured into the mold. Once the material solidifies, the final part is ejected from the machine and the process is repeated in rapid succession.

Casting involves filling a mold with molten metal or other liquefied material. The molten material cools and hardens inside the mold to form the desired product. Casting is commonly used to make metal products as well as silicone and plastic parts.
