    Rubber mold According to the mold structure and product production process is divided into: pressing molding die, die-casting mold, injection molding mold, extrusion mold Four common molds, as well as some special rubber products, such as special rubber molds.

    1. Pressing Molding mould

    Also known as normal die. It is a mixed, processed into a certain shape and weighing of semi-finished materials directly into the mold, and then into the flat vulcanizing machine pressure, heating. The rubber material is formed under pressure and heating.

    Characteristics: The mold structure is simple, the versatility is strong, the use surface is wide, the operation is convenient, therefore occupies the big proportion in the rubber molded product.

    2 Die Casting Mould

    Also known as transfer mold or extrusion mold. It is mixed, simple shape, limited to a certain amount of plastic or semi-finished products into the die-casting material cavity, through the pressure of the die-casting plug to squeeze the rubber, and make the glue material through the pouring system into the mold cavity vulcanization stereotypes.

    Features: more complex than ordinary die, suitable for the production of ordinary molding can not be suppressed or forced to suppress thin-walled, slender and flexible products, as well as complex shape, difficult to feed rubber products. The use of this mold production of products of good compactness, superior quality.

    3. Injection Molding Mould

    It is the plastic material of the pre heating into the injection mold of the pouring system injection molding vulcanization.

    Features: complex structure, suitable for large, thick wall, thin-walled, complex shape products. High production efficiency, stable quality, can achieve automated production.

    4. Extrusion Molding Mould

    Through the molding die made of various cross-section shape of the rubber profile semi-finished products, to achieve the purpose of the initial modelling, and then after the cooling and stereotypes transported to the vulcanization tank for vulcanization or as a die-forming process required for preformed semi-finished rubber.

    Features: High production efficiency, stable quality, can realize automatic production.
