Molding silicone rubber

Molding silicone rubber
1. Applications of molding silicone rubber 
Molding silicone rubber is primarily intended for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts ,unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry, a large statue Buddha, furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.

2. Features of molding silicone rubber: 
Molding silicone rubber is white or red flowing liquid with general hardness of 22-50A after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

3. Operations of molding silicone rubber 
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds require fast drying and demolding, more curing agent is needed; contrarily, if molds require slower drying and demolding, less curing agent is needed.
 
(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demolding.)

4. Frequently asked questions of molding silicone rubber
Why does the silicone rubber mold have few molding times?
       The silicone rubber mold has few molding times is due to following reasons: adding too much silicone oil will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber may make it easy to break; making the mold for large products with soft silicone rubber will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take proper silicone rubber to make the mold for suitable products.
