manual mold silicone rubber applications
1.manual mold silicone rubber applications
Manual Mold silicon rubber silicone rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, low melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.

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

3.manual mold silicone rubber operations
Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicon rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use. One pair of mold can be solidified and formed in 2-3 hours.
(Note: our company does not recommend you to add silicon oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicon oil can be added to soften the mold for easy demold.)

Frequently asked questions of manual mold Silicon rubber
1.What should we do when the air bubbles appeared in the process of making manual mold silicone rubber ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to de-air. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-cross linking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.
