manual mold silicone rubber for mold making

Introduction of mold making silicone rubber:

mold making silicone rubber is a kind of liquid fluid, features good fluidity and good operation., large duplication times

Features of mold making silicone  silicone:

mold making silicone rubber has good elasticity, non-deformation , high temperature resistance, low shrinkage. And it is suitable for manual mold design and small duplication mold production. 

Operations of mold making silicone rubber:

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Step Two: vacuum pumping

Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available 

Step Three: Perfusion Molding

The perfusion molding is an easy way to make molds, it’s Slowly and evenly perfuse the mixed silicon rubber into the square frame. After the cross linking reaction.

Why should the silicone mold be reused only for a few times?

It can be due to the following reasons:

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
