People who have done silicone molds know that improper selection of silicone hardness can cause deformation of silicone molds. Large-size products must be opened with hard silicone, and small-sized products or products with complex patterns must use small hardness (soft ) The silicone to do the mold. What are the reasons? Let's take a look at the following.
Normally the hardness of the mold silicone varies from 0 to 60 degrees, and the hardness is 20 degrees to 40 degrees. The details are as follows:
0 degree silica gel is a super soft silicone, color is translucent liquid, with excellent motor and chemical chaos, weather aging, physiological inertia, non-toxic tasteless, low line shrinkage and other easy-to-manipulate characteristics; Human body shape, sexual products, chest stickers, artificial body surfaces, etc.;
5-10 degree low hardness mold silicone is used for sexual products, human prosthetics, delicate patterns and soft soap crafts;
10 degrees to 25 degrees is recommended to be used in the reproduction of a very fine pattern product model, to perform perfusion mold manipulation, this mold opening method is relatively easy to release, and will not damage the product inside the silicone mold, can be used for cake mold, chocolate mold, Make candles, various craft models
25 degrees to 40 degrees are used for the production of models such as cement, mixed soil, culture stone, and rapid prototyping;
40-60 degree high hardness silicone is generally leather embossed silicone, mainly used for mold making, leather pattern reproduction, leather pattern pressing and so on.
