Applications of molding silicone rubber

Molding silicone rubberis primarily intended for the duplication and mold making of poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts industry, furniture decoration materials, Buddhist statue crafts, building decoration materials, large-scale cement mold, artificial fossils factory, Europe component factory, simulative landscapes, animals and plants sculpture, sandstone crafts and so on.

Features of molding silicone rubber

Molding silicone rubberis a kind of white or red flowing liquid with general hardness of ****0A° after curing. Molding silicon rubber is elastic and high-temperature resistant and acid & alkali resistant. Molding silicone rubber also has the features of non-deformation, good tension and high tensile and tear strength.

Operations of molding silicone rubber

If the customer wants to make large products and large sized molds, the mold should be made of silicon rubber with high hardness. On the contrary, customers need to chose the silicone rubber with low hardness when making the molds with fine and precision patterns. The amount of the curing agent depends on the actual requirements of the customer. If molds requires fast drying and demold, more curing agent is needed. Contrarily, less curing agent is needed if molds requires slower drying and demold.

(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%**0% silicone oil can be added to soften the mold for easy demolding.)

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 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.
