Silicone Mold Can Achieve Automated Production

Aug 01, 2017

Silicone mold is the production of special mold glue, silicone is characterized by high temperature resistance, corrosion resistance, tearing tensile strength, simulation fine high, is to do a variety of crafts mold.

Silicone mold has three types of open mode: Bao (perfusion mold), rinse die (chip). Mold silicone is a flow of white liquid, divided into 22 groups: A group is silica gel, B is curing agent, Mold Making Silicone Rubber such as 100 grams of silica gel added 2% curing agent stirring evenly, you can do the following:

Brush Mold (die): General Brush three layer according to the requirements of the mold multi-layer, the first layer of brush in the mold to draw vacuum, brush in place. Mold Making Silicone Rubber The second layer of gauze, the third layer coated with silica gel, so that curing molding.

Introduction of several major classifications of silicone mould

1. Pressing MOULDING 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, Mold Making Silicone Rubber and then into the flat vulcanizing machine pressure, heating.

The rubber material is formed under the 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 Mold: Also known as transfer mold or extrusion mold. It is mixed, simple shape, Mold Making Silicone Rubber 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, Mold Making Silicone Rubber 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 a plastic material which is preformed to be heated into the mold by injecting the injection molding system into the molding vulcanization.

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

4. Extrusion Molding Mold: Through the head of the molding die made of various sections of the shape of the rubber profile semi-finished products, to achieve the purpose of the initial modelling, and then through the cooling to the curing tank to the vulcanization or used as a pressure molding method required for the preformed semi-finished rubber.

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