Mainly used for toys, craft gifts, pattern of fine products, mold, casting mold products, POLI crafts, resin crafts, lighting, candles, and other arts and crafts of the complex model and precision mold manufacturing.

Characteristics of silica gel:

Liquid mold silicone, with excellent liquidity, good operation, not deformation, high temperature, acid and alkali, not expansion, tensile, tear

Tensile strength is good, turn over the mold for many times, repeated use, small products suitable for small precision or complex pattern. And easy to demould, shrinkage

Can reach 2/1000.

The operation of liquid mould silica gel:

1 silica gel and curing agent mixing evenly. Mold silicone appearance is the flow of liquid, A group is a silica gel, B group is a curing agent. Take 100

Grams of silica gel, adding 2 grams of curing agent (Note: silicone gel and curing agent must be stirring evenly, if not stir evenly, the mold will be a piece of

Has been cured, a piece of no cure, the silicone will appear dry curing uneven conditions will affect the service life of silicone mold and turn over the mold

Number, and even cause the mold scrap condition.

2 vacuum exhaust bubble treatment: after the mixing of silica gel and curing agent, the process of pumping vacuum exhaust bubble is not too long,

Under normal circumstances, not more than ten minutes, the vacuum pumping time is too long, the silica gel immediately solidified, resulting in a cross-linking reaction, so that the silica gel into a piece of

A block to brushing or perfusion, thus wasting the silica gel, only the silica gel into the trash can, to retake silica gel.

3 brushing or operation process: the evacuation of the bubble in the silica gel, in order to brush or perfusion. Pour the product above (Note: in the inverted silica gel

The product or model that must be reproduced before must be played with release agent or isolation agent. And then the silica gel in the product above, brushing must be all

Well, 30 minutes after pasting a layer of gauze weft cloth to increase the fiber strength and the tension of silica gel. And then coated with a layer of silica gel, and then paste a layer of gauze

Weft cloth, so after the two can be. Only in this way, the opening of the silicone mold service life and the number of times to increase the number of

More, can save cost, improve efficiency.

4. The external mode of production: using the general methods and materials is around the mold, surrounded by plastic or wood, with plaster fill the model cabinet

Can be, and another way of using resin, brushing a layer of resin on the paste layer of glass fiber cloth, and then again and again, and then paste two or three

Layer on the mold can be completed outside the mold.
