Manual mold silicone rubber applications Manual mold silicone rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, 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. 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% to 3% solid curing agent, and mix evenly and they are ready for use. One pair of mold can be solidified and formed in 2 to 3 hours. Frequently asked questions for Manual mold silicone rubber 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. 25kg/drum and 200kg/drum.
