A brief analysis of liquid silicone for crafts mol...

Handicrafts manufacturing and imitation of ancient cultural relics is an important means of researching, inheriting and carrying forward the cultural heritage of our country. The molds used in the production of handicrafts are different from the ordinary mold. Generally, crafts with complex shape require clear texture and smooth surface, while the requirements of dimensional accuracy are not too high. These characteristics make it is difficult to make use of general mold to make arts and crafts. Since stripping difficulties, it needs to be split into many pieces of craft mold, which is hard to ensure that the body contour and texture of clarity of technology products, but also produces a lot of flat-fell seam. For these more complex mold shapes, particularly craft molds, a method of machining is difficult to accomplish. Therefore, the only way to manufacture these craft moulds is to engrave. In this way, the manufacturing cycle of a craft mold engraving often up to several months, so that the mold manufacturing costs remain high, which can't achieve rapid manufacturing of craft moulds. Now we can use the technology of RT (Rapid Tooling) to manufacture these craft moulds, for example, the manufacture of silicone rubber mold is very easy, which can easily overcome the resistance and completely meet the production requirements for crafts. This cycle has been shortened 1/3-1/5 by using RT technology than the traditional nc manufacture of moulds, and the economic benefit is remarkable.   Liquid silicone for crafts molding is a kind of mold making methods of RT technology. Silicone rubber mold with good flexibility and elasticity can be directly removed after completion of the production casting for complex structure, fine decorative pattern, and no slope or inverted taper angle as well as deep groove parts, which are the advantages of the silicone rubber for craft molds making.     The main component of liquid silicone for crafts molding is silicon dioxide, which is a kind of amorphous machine manufactured goods made of silica in sodium silicate and sulfuric acid. It is composed of mineral existing in nature after washing, becoming a bead after machining. Its structure is very much like a sponge which can absorb and save water. Under the condition of humidity is 100%, it can absorb and condense 40% water vapor equivalent to 40% of its own weight.   Uses of liquid silicone for crafts molding: Craft liquid silicone is manly applicable to toys, craft gifts, decorative pattern, fine products, pouring and wrapping mold products, POLI handicraft, resin handicraft, lighting, candles and other crafts of complex mode and precision mold manufacturing.   Operating guide of liquid silicone for craft mold making: There are three ways to make craft molds, which are pouring mould, wrapping mould and brushing mould making. Liquid silicone for crafts molding is flowing white liquid silicone rubber, which consisted of two components: A group is silicone and B group is the curing agent. It is the first step that takes 100g of part A and adds 2g of part B and mix the silicone rubber and curing agent evenly. Then, take the mixture to de-air for 3-5 minutes. Next, pouring the mixture into the frame with original gypsum mold slowly.   Shenzhen Hong Ye Jie Technology Co., Ltd. is the liquid silicone for crafts molding manufacturer.
