Silicon rubber for pad printing application:
silicon rubber for pad printing is mainly applicable to making pads for plastics toys, electroplating products, electronic toys, trademarks and irregular pattern printing.printing silicon rubber pads is a carrier which transfer printing the patterns on the steel plate onto the toy products' surface.
Silicon rubber for pad printing features:
Silicon rubber for pad printing with the advantages of abrasion resistance,high temperature resistance, good printing effect, etc., which made of top-quality raw material due to adding American Dupont Teflon high-temperature resistance new material, is processed through high-temperature machining.

Silicon rubber for pad printing operation instructions.
Component A is flowing liquid and component B is the curing agent. For example, take silicon rubber of 100g and add 2g curing agent for mixing evenly (silicon rubber and curing agent must be measured accurately). After the silicon rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicon rubber into pads mold.if you don't have vacuum machine,please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself.since the less curing agent you add,the slower the mould will curdle, the bubbles will bubble out itself.
Frequently asked questions of pad printing silicon rubber
Why print pads can't print pattern perfectly ?
1>Silicon rubber pads are too hard to pad perfect pattern,because the pattern or flower pattern are too fine while the pads are too hard,the print pads havent absorb the ink from armor plate to the p |
