Mold Making Silicon
Applications of Mold making silicon: Mould making silicon rubber is mainly used in toys, gifts, decoration, plate engrave, human replica, art crafts, resin crafts, poly resin crafts, unsatured resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist statue crafts, etc.

Features of Mold making silicon: Mold making silicon has good characteristics of easy operation, light viscosity and good flowability, low shrinkage, favorable tension, No-deformation favorable hardness and high temperature, acid alkali and ageing resistance.

Basic description of Mold making silicon: Mold making silicon is a kind of silicon consisted with two part, one is silicon another one is catalyst, the ratio is 100: 2 under temperature 25° The operating time of mold making silicon is half an hour, demould time 6-8 hours. If customers make molds in brushing way, 628 and 638 are good choices as they have moderate viscosity.

FAQ for mold making silicon:
Why the silicon mold just can be reproduced for a few times?
A: Adding too much silicon oil into silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicon rubber and reduce the tension and tear strength.

B: Using the silicon rubber a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to make molds for large sized products with simple designs. So we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.
