A mold is needed for debossed, embossed, colorfilled styles. We make a mold and set it in the machine, the high temperature of about 200℃ will solidify rubber into the sharp of bracelet.bottle opener keychain let"s see how the mould come into being. Mold, industrial production to use injection, blow molding, extrusion, die-casting or forging and forming, smelting, stamping and other methods to get the various models and tools of the required products. In short, mold is used to make molding tools. This tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the articles by changing the physical state of the formed material. It has the title of "the mother of industry". Under the action of external force, the billet becomes a tool with specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, compaction of powder metallurgy parts, pressure casting, and plastic or injection molding of engineering plastics, rubber, ceramics and other products.

When separate parts are removed, the blank is injected into the mold cavity to form. The mold is a precision tool with complex shape, bearing the bulging force of the billet. It has high requirements for the structure strength, stiffness, surface hardness, surface roughness and machining precision. The development level of die production is one of the important symbols of the mechanical manufacturing level.
