Technology

Silicon Rubber Plate & Silicon Rubber Roller

Author:Ivan Zhang
Silicon rubber rubber is used in the processes of flat-to flat hot stamping and flat-to-roller technology,and silicon rubber roller in the rotary hot stamping and roller-to-flat process.They function as heat transferring and pressure offset.

1.Heat Transferring
In the processes of hot stamping and heat-transfer technology,the adhesive on the top layer of the foil or heat-transfer material is melt by the heat transfered over a silicon rubber plate/silicon rubber roller and the graphic is achieved on the objects.

2.Pressure Offset
In the processes of hot stamping and heat-transfer technology,silicon rubber plate or silicon rubber roller can provide the plastic objects with the pressure offset during the process.Therefore,they are usually used to decorate the more rigid objects rather than paper and films.

3.Color
There are a few colors for these silicon rubber plate and silicon rubber roller,eg.red,white,yellow,black,etc.,among which,red silicon rubber is the most popular in the hot stamping process.

4.Rigidity
Rigidity,is a key factor for the elastic substance,such as rubber.So is silicon rubber plate or silicon rubber roller.Rigidity,indicates the elastic substance's ability to resist to the physical force.More rigid,less distorting under the same physical force.Therefore,under the same physical force,a more rigid silicon rubber plate or silicon rubber roller can produce the more sharp and accurate texts or graphics.You can utilize a Shawn sclerometer to test the rigidity of silicon rubber plate or silicon rubber roller.

5.Thickness
Usually,silicon rubber plate consists of aluminum backing and silicon rubber layer,which are fixed together through a layer of metal-nonmetal adhesive.Thicker the aluminum backing,more even the rigidity of the silicon rubber plate/roller.The less thicker aluminum backing means flexibility,which means to readily setup the silicon rubber plate/roller's position for the operator.
