1) Description for manual molding silicone rubber:
manual molding silicone rubber is flowing liquid with consistent quality in whatever color. It consists of two components, wherein component A is silicone rubber, and component B is curing agent or vulcanizing agent. Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% curing agent, and mix evenly for use. One mold pair can be solidified and formed in 2-3 hours. The formed mold can be used repeatedly without deformation and water shrinkage and with high temperature resistance, thereby providing fast duplication of the product with product shrinkage 2. Manual mold silicon is mainly applicable to manual molds and small number of product duplication.
2) Applications for manual molding silicone rubber:
Manual Mold Silicone Rubber for is mainly applicable to manual mold design, PVC plastic molds, cement product molds, electronic toy cars, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.
3) Manual Mold Silicone Rubber features:
Manual Mold Silicone Rubber has the features of resistance to deformation, good tensile strength and low shrinkage. And times of reproduction are up to customers need.

5) Frequently asked questions for Silicone rubber for manual mold
What should we do when the air bubbles appeared in the process of mold making?
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 deair. 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-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.
