Silicone mold hardness selection-HongYe silicone

Mold, it is a kind of industrial processes and products, in the industrial production injection molding, blow molding, extrusion by casting or forging, smelting, molding, stamping, stretching and other methods to obtain the required products in a variety of models and tools. In short, the mold is used for molding articles from a variety of tools, this tool parts, different mold is made up of many different parts. It is mainly through the molding material physical state changes to achieve the objects shape processing. Mold on the basis of the material used is different, can be divided into a metal mold, metal mold two class. On the basis of using different materials, today focuses on non metal mold of silicone molds, silicone mold is a kind of new environmental protection materials, mainly for the gift industry, furniture industry, character copy, resin handicraft industry, candles, plastic toy industry, gift stationery industry, plaster crafts industry, Boli industrial products, simulation, Buddha sculptures of animals and plants carving crafts and other sectors of the product copy. Silicone mold hardness model selection: Silicone mold is an important parameter, which is the hardness. Based on the model of product characteristics, we choose different hardness silicone material. Generally speaking, hardness of 20 degrees around the silicone, suitable for small product and pattern fine products, usually the product size below 1 meters, because this type of silica gel with: low viscosity, good fluidity, good operation, easy to discharge foam, tensile tear strength, easily bored. For large size products, usually the size of 1 meters, is the use of relatively large silicone mold hardness
