 RTV-2 silicon for shoe sole mold making Application of 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 RTV-2 silicon for shoe sole mold making:

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.

Note: The time for vacuum-pumping should be less than 3—5 mins ,otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.

  FAQs of the RTV-2 silicon for shoe sole mold making 

What should you do for deformation of the silicone mold ?

It should deal apart according to the size of the products, In principle, the hardness of the silicone should be according to the size of the products. If the products features small size and detailed patterns on it, the soft silicone can be applicable which the shore A should be 15-20 for easy demoulding and not damage of the patterns. Other wise harder silicone should be needed for large size products, such as products with size 50cm will need harder silicone with 40-50 shore A , then no-deformation. If Large products but features detailed patterns then 30 shore A silicone will be workable.(The process should be a layer silicone add a layer fiber glass or cloth..).The outer of mold can be plaster, glass fiber reinforced plastic(unsaturated resin and fiber glass) to protect the products from deformation.
