| Manual mold silicone rubber Product Description Manual mold silicone is a flowable liquid, and the quality has nothing to do with the color. It consists of two components. Part A is a flowable liquid silicone rubber, part B is the curing agent. Firstly, after 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. Product Feature 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. Product Specification/Models Specification of manual mold silicone: HY-528# is applicable to make molds of smaller products and the reduplication will be 2-3 times. HY-540# , compared to other two types, for its moderate hardness and better quality & performance, its reduplication will be 20-30 times. HY-570# is applicable to large size products duplications and Electronic equipment antivibration. Application 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. Other Information FAQs of the manual mold silicone 1.How to deal with the bubbles during the mixing process? It depends on your practical situation. Firstly you can deal the mixture with a vacuum machine 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. 2. The solutions of the sticky of the silicone mold? a.The main reason for this problem is that you do not handle the products or original molds well, then you should deal with the original mold or products carefully before molding. Such as for the products with a complicated pattern or a unsmoothed surface, you should polish and clean the products after which it will be molded ,then spray the release agent. Normally, the release agent can be Vaseline , detergent. liquid wax Etc. In practical process, you can brush different release agent according to different material. b. 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 partialy cured. 3. 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 consistent to the size of the products. For the small size products with detailed patterns, 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 |
