Silicon Rubber Plate & Silicon Rubber Roller
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.
 
 
Hot Stamping & Heat-transfer Technology
      There are four types of hot stamping presses according to the stamping methods and substrate's shapes.

      1.Roller-to-Flat Hot Stamping

       Roller-to-flat hot stamping,is actually based on the principle of flat heat-transfer press,which is primarily used to decorate the planar objects and curved objects.Typically,a object that is completely required to be decorated,appliance panel,some facet of cosmetic packaging,top of the plastic box or wooden jewelry box,toys,PVC sheet,ski,and plastic posts are suitable to be decorated by a roller-to-flat hot stamping press .If a floating device is installed on the working station,roller-to-flat hot stamping press is also used to decorate the complex objects.

      2.Rotary Hot Stamping

      Rotary hot stamping is based on the principle of rotary heat-transfer press.

      (1)For Empty Platic Bottle

      For the rigid bottle,is able to endure the pressure of roller.so,such bottle is directly decorated plus an axis position system;For the pliable bottle,is decorated after the bottle full of air to support the roller.

     (2)Plastic Pliable Tube

   Toothpaste,shampoo,bodycare,gel's container,or tubes are dcorated by this press if a supporting axis is installed.

     3.Flat-to-flat Fot Stamping

   Flat-to-flat hot stamping press is suitable to decorate texts or logo onto some part of a planar object,such as VCD panel.

     4.Flat-to-roller Hot Stamping

     The flat-to-roller hot stamping press,is suitable to decorate the round objects,such as plastic cap, ball-point pen,soft tube,round dial,golf cue,cosmetic box and food plastic packaging.
