Introduction about Manual Mold Silicone

Manual mold silicone rubber is mainly used for model design of manual mold, PVC plastic molds, cement products, low melting point alloy molds, alloy toys, plastic toys, electronics, handicrafts,                  stationery, large-scale sculpture, reproduction of cultural relic, shoe sole molds, pad printing allocation, Electronic equipment antivibration, and so on. 　　

Operation Instruction of manual mold silicone: 　　                                                                                                                                                                                                                                                            Manual mold silicone is a flowable liquid, and the quality has nothing to do with the color. It consists of two component. Part A is a flowable liquid silicone rubber, part B is the curing agent.                                Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber , add 2%-3% curing agent of the amount of silicon, and mix them evenly.                                                          Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-3 hours. 　　                                                                                                                                 

How to deal with the bubbles during the mixing process? 　　                                                                                                                                                                                                                                            It depends on your practical situation. Firstly you can deal the mixture with a vacuumizer if you have one; If no such machine, you can reduce the mixing ratio of the hardener from 4% to 1%-2%.                          Then in the prior period of the reaction of the mixture will be slower, then the air in the mixture will exhaust by itself for a longer curing time to release the bubble. 　　

What should you do for imcomplete curing after the mold is finished? 　　                                                                                                                                                                                                                          Two factors lead to this problem: 1. Inexact mixing ratio, not to weigh following the standard ; 2 .The mixture of the silicone and catalyst is not mixed evenly.                                                                               You should avoid this kind of problem ,otherwise there will be a waste of silicone mold. 　　                                                                                                                                                                                        The second reason is that the operator pour the silicone into the mold when the mixture is mixed evenly, then the finish silicone mold will not cure and dry entirely.
