Manual molding silicon rubber

Manual molding silicon rubber applications

Manual molding silicon rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.

Manual molding silicon rubber  features

Manual molding silicon rubber is white or red flowing liquid with general hardness of 22-50A°after curing. Requirements for the silicone rubber: low shrinkage, no deformation of the mould, good elasticity, the more moulds duplicated the better, etc.

Frequently asked questions of Manual molding silicon rubber

What should we do if a silicon rubber mold product deforms? 

The solution depends on the size of the product. In principle, the size of the product should be in direct proportion to the hardness of the silicon rubber. 

Regarding small or very fine detailed products, soft silico  with hardness of 10-20 shore A is required for easier demould without damaging the lines of the fine products. Regarding large products, such as products with size above 50 cm, silicon rubber with hardness of 40-50 shore A  is required for non-deformation. 

Regarding large but fine products, silicon rubber with hardness of about 30 shore A can be used for mold making (the method is to brush a layer silicon rubber  and then paste a layer of glass fiber cloth and brush another silicone rubber), the outer mold can be made of gypsum, fiberglass reinforced plastics (unsaturated resin plus glass fiber cloth) for preventing the products from deforming.
