The elements of monochrome pad printing machine to complete printing include pad printing plate, pad printing ink, pad printing rubber head, and pad printing fixture. The pad printing fixture is actually a positioning device, which fixes the product on the workbench according to the printing requirements to ensure that it does not move during the printing process; the pad printing ink should be suitable for the material of the product, such as plastic, glass, metal, The color of pad printing ink should also be the same as the color of the printing design; the pad printing plate is to etch the printed graphics on the steel plate or resin plate; the pad printing rubber head is an important carrier to complete the ink transfer, it is made of silicone rubber vulcanization, different pictures The printing plate of the text needs pad printing pads of different shapes and hardness. Monochrome pad printing machines generally only need one fixture, one printing plate, one color ink and one pad printing head.

      Monochrome rotary pad printing machine is the most popular pad printing machine in the market at present. Its degree of automation is greatly improved compared with monochrome pad printing machine. Compared with monochrome pad printing machine, its notable feature is that the Instead of a rotating turntable, it can clamp 4-10 products for continuous pad printing. Therefore, it needs more fixtures to fix each product. The elements to complete printing include pad printing plates, pad printing inks, and pad printing pads. , pad printing fixture. The pad printing fixture is actually a positioning device, which fixes the product on the workbench according to the printing requirements to ensure that it does not move during the printing process; the pad printing ink should be suitable for the material of the product, such as plastic, glass, metal, and pad printing ink. The color should also be the same as the color of the printing design; the pad printing plate is to etch the printed graphics on the steel plate or resin plate; the pad printing rubber head is an important carrier to complete the ink transfer, it is made of silicone rubber vulcanization, different pictures The printing plate of the text needs pad printing pads of different shapes and hardness. A monochrome rotary pad printer generally needs 4 to 10 fixtures, a printing plate, a color ink and a pad printing head.

           Among multi-color pad printers, shuttle type pad printers and turntable pad printers are more common, while shuttle type pad printers have the highest precision. The workbench of the shuttle pad printing machine has an accessory similar to a shuttle block, which will drive the product and the fixture to move back and forth in different printing positions, and complete multi-color pad printing in sequence. The important feature of the multi-color pad printing machine is that it has multiple sets of colors and pad printing systems: Fixtures: The shuttle-type pad printing machine has only one fixture just like the single-color pad printing machine, but the fixture of the multi-color pad printing machine will move back and forth; The four-color shuttle pad printing machine has four sets of ink supply systems, which add four different colors of ink respectively. The four ink supply systems are respectively equipped with four pad printing plates, and each pad printing plate is supplied with ink by a separate oil cup or oil pan. , and the etching sequence of the four pad printing plates should be made according to the original manuscript provided by the user; the four-color shuttle pad printing machine has four pad printing pads installed on the front ends of different steel plates respectively, and the shapes of the pad printing pads can be the same or can be different.
