Product description

Introduction to pad printing silicone:

Pad printing silicone is also called pad printing glue, pad printing silicone, rubber head silicone, etc. It is a two-component liquid silicone is the material of choice for making pad printing rubber heads.

The use of pad printing silica gel:

Pad printing rubber is specially used to manufacture pad printing rubber heads. Pad printing plastic head is to use the pattern on the steel plate as a carrier through the plastic head, then transfer the pattern on the steel plate to the toy product to print irregular patterns. It is mainly used for plastic toys, electroplating products, electronic toys, trademarks, communication equipment. , Electronic products, craft gift stationery other irregular pattern printing.

Features of pad printing silicone:

1. Good fluidity, low shrinkage, good elasticity no deformation;

2. The gum is fine without impurities, has good fluidity no bubbles;

3. Good oiling oiling effect, clear pattern printing;

4. Wear-resistant, the number of printed plastic heads can reach tens of thousands.

Pad printing silica gel operation:

1. the crystal pad printing rubber head mold to be made, evenly spray the mold release machine for use;

1. Mix the AB components of pad printing silica gel according to the ratio of 100:2 mix them evenly, weigh them with the help of an electronic scale;

2. Put the mixed rubber material into a vacuum machine for vacuuming de-bubble treatment, the rubber head will be smoother more durable without bubbles;

3. Slowly pour the vacuumized glue into the crystal mold, let it flow naturally, then let it stand;

4. After the pad printing glue in the crystal mold is completely cured, the mold can be demolded. After demolding, the glue head is recommended to be used in a ventilated place for 24 hours to ensure the good performance of the pad printing glue head.
