Silicone rubber for manual moulding features

the manual mold silicone rubber features with the resistance to deformation, good tensile strength as well as low shrinkage, and time of reproduction determined on the basis of customers.

Silicone rubber for manual moulding operations

Firstly process and prepare the model mould or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use. One pair of mould can be solidified and formed in 2-3 hours.

(Note: our company does not recommend you to add silicone oil. If a special soft silicone mould or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)

Frequently asked questions for Silicone rubber for manual moulding

What should we do when the air bubbles appeared in the process of mould making ?

To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicone rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicone rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicone rubber will slow down, so, the air in the mold will be eliminated gradually to reduce the air bubbles.
