Molding silicone its plasticity, durability and heat resistance of all ages, silicone is a synthetic material, in many molding process in the modern industrial design engineering. It is suitable for emerging industrial parts, such as seals, connectors, or film, of. Designers can also use silicon to make a master copy of the mold, which is repeated for the vote. Carnegie - Mellon University, pointed out that the polymer material is toxic, so protective clothing should be worn in any related production.
Compression molding
Compression molding is a complex technology, commonly used in the manufacture of rubber parts. It works in a heated mold to melt the organic silicon compounds, and to exert pressure on the shape of compounds reflect the same. It Meere industry, compression molding, reduce waste and have a "minimal" seam shape. This technology also has a large and complex parts production advantage. Dow Corning low production costs, compression molding cost-effective way to "short" and "start production."
Injection molding
Molding silicone injection molding, and the other common techniques, including pushing through a funnel into a heated mold sealing and silicone compounds. According to Stockwell elastomer, silicone rubber material than the gum, this process is more appropriate, because it takes less time to set. Because it is evenly filled with a silicone mold, injection molding, is more closely meet the production needs of "tolerance", such as baby bottle nipples object. It also has the advantage of short cycle times, achieve high productivity.
Extrusion
In extrusion, silicone is forced through the known shape of the molding and die cutting equipment. It is a complex process, Dow Corning has a high yield, with the fluctuations of the mold cost and profit margins. However, it stresses the fabrication of "cross section" of the object, such as wire insulation or pipe rods, its applicability.
Calendering
Molding silicone calendering, compressed into a piece of silicon. It is the production of organic silicon thin, it can be used to make fabric waterproof, sealant, or the ability to protect. In addition, it can produce long plastic sheets, because the compound can be set, and in the molding process to form.
