molding silicone rubber

Molding silicone rubber features : a. good characteristics of easy-operation b.light viscosity and good flowability c. favorable tension d. low shrinkage e. no deformation f. high temperaure resistance, acid and alkali-resistance and ageing resistance molding silicone rubber application: molding silicone rubber is suitatble for Product duplication and mold manufacture such as 1. toys, gifts 2. decoration, plate engrave 3. human replica, art crafts, 4. resin crafts, unsaturated resin crafts 5. poly resin crafts, candle crafts, plastic crafts 6. stationeries, plaster crafts, Bunddhist statue crafts, etc. Advantage of molding silicone rubber: Molding silicone rubber has advantage of excelenlt fluidity and good operational performance, an elastic silicone rubber mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion, comfortable duplication times and free sample avalibale. molding silicone rubber detaials: Place of Origin: Guangdong, China(Mainland) Brand Name: Hong Ye silicone rubber Model Number: HY620#, HY628#, HY638#, HY640# Molding silicone rubber for Payment & Shipping Terms MOQ: 200Kilogram/Kilograms Price: FOB Shenzhen USD6.2~8.3/Kilogram Package Details: 25kg/drum and 200kg/drum Delivery Time: within 3 days after getting your bank receipt Payment Terms: T/T, L/C Supplier ability: 8Ton/ day Molding silicone rubber operations: mould silicone rubber is a kind of flowing liquid, and it consists of two component, part A is aflowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the origianal moldel, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix them evenly. Then after vacuum-pumping the mixture, you cn pour it into the mold frame. The sillicone mold will cured in 2~3 hours. Note: the time for vacuum-pumping should be less than 3-5mins, othewise, once the silicone rubber has cross-link reaction during vacuumizing. it will not be operated. Molding silicone rubber with FOQ: 1. Why does the silicone rubber mold have few molding times? The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products. 　　 2. Why does the mold made of silicone rubber have an unsmooth surface with tracks and strips on it? 　　It is due to product or model to be molded should hasn't been sanded or polished . If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the mold or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also bring about unsmoothness of the mold.
