3.Operations of shoe mould making silicones:

The proportions and reactions of the curing agent and the silicon are listed as follows:

1. Adding curing agent 1%, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours.

2. Adding curing agent 2%, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.

3. Adding curing agent 3%, the silicone can still be operated within 28 - 30 minutes and can be demoulded after 1.5-2 hours.

4. Adding curing agent 4%, the silicone can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.

FAQ of shoe mould making silicones

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

It can be due to the following reasons:

a. Adding too much silicone oil into silicon rubber. Silicon oil is an additive which destroies the molecular chain 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.
