Silicone Rubber Mould

Silicone mould is a special mold for making crafts. According to performance, the raw materials of glue can be divided into ordinary silicone and weather silicone. The characteristics of silicone are high temperature resistance, corrosion resistance, strong tear resistance, high simulation precision, and it is used to make various handicrafts mold.

Mold should be made in time after the silicone is matched. Pour the glue on the highest part of the mold in a trickle, let it flow naturally, brush it in place with an oil paintbrush where the flow is not in place, if it is a piece of silicone, not only fill the entire product, but also brush the glue evenly. Each product should be brushed with at least three layers of silicone. The thickness of each layer of silicone is 1mm. In the process of brushing the silicone, each layer is required to be cured before the other layer can be brushed. When brushing the third layer, add one layer on top of the second layer. The thickness of the silica gel part of the whole mold is controlled in 3-4mm according to the different requirements of the size of the product, and the width is not greater than 60 mm of the product width. The time for the silicone to set is 20 minutes.
