Chinese supplier of pad printing silicone material

The transfer printing process is used to transfer the ink from an etched printing plate to lots of kinds of surface by using a silicone rubber pad. The big advantage of this method of printing is its ability to print on virtually any kind of irregular surface. For example, it is used to print patterns on plastics, metals and ceramics. Hong ye is a Chinese supplier of pad printing silicone material. The following is about the pad printing process.       Step 1: The printing cycle begins by flooding the etched area of the printing plate with ink. Pad printing machines use either an open inkwell or a closed ink cup. The ink must have a low viscosity allowing it to flow out evenly over the surface and into the etched image area. Step 2: The top surface of the plate should be cleaned by using a doctor blade, leaving the printing ink in the etched area containing the image. Step 3: The silicone transfer pad is compressed onto the surface of the plate, pushing air out of the way as it compresses. Step 4: After the pad is lifted from the plate the surface of the ink film on the silicone pad starts to dry, making that surface become tackier. Step 5: The pad is compressed onto the surface of the substrate, so the tackiness of the ink's surface enables it to leave the pad and stick to the target substrate. Step 6: The pad lifts away from the surface of the substrate, assuming its original shape. The silicone rubber pad will lift away clean and ready for the next print cycle.   The pad’s shape, hardness, and surface finish determine the pickup and transfer characteristics of each pad and the final print quality of the finished article.   It's a relatively simple process to mould silicone rubber pads. There are two basic types of silicone chemistry used in the formulation of 2 Part RTV silicones and they are referred to as addition cure and condensation cure .With a variation of as little as 4 Shore A from the expected hardness level, you will begin to notice changes in the print quality produced by the silicone pad. So it is very important for you to choose a qualified supplier to ensure its stability of its silicone products.   Hong Ye Jie technology Co. Ltd is always willing to supply pad printing silicones material. Do you want to get more detailed information about Hongye’s considerate service and products?
