Pad Printing

The principle of silkscreen printing
　　Through the role of the glue head will be engraved on the steel plate pattern transfer to the workpiece, similar to the daily work of the stamp Through the pressure of the glue scraper will be the ink from the mesh of the screen to penetrate the product, forming a pattern
　　The printing area of pad printing has a certain limit, at present the largest printing surface can be 150 * 450MM, but not full plate printing, but intermittent character class, full plate printing, the current maximum to 300MM diameter, but the cost of consumables (glue head) will be very high printing area basically no limit, full plate printing can reach 1500 * 2000MM, consumables (stencil) cost The cost of consumables (stencil) is low and can be reused.
　　There is no restriction on the shape of the product, flat, curved or wavy surfaces, as long as the glue head deformation can be reached The printing surface of the product must be flat, pure or regular curved
　　Print quality High High
　　The pad printing machine can do up to 12 sets of colours in one machine, and the product will be printed out at once, and the cost is low, suitable for general factory investment The screen printing machine can also do multi-colour overprinting, but the multi-colour overprinting screen printing machine is very expensive, not suitable for general factory investment, manual walking table one-time multi-colour overprinting occupies a large area, more labour.
　　Features pad printing ink layer is thin, can be printed on any surface overlay, showing very good colour expression and printing adaptability, commonly known as universal printing, in addition to water and air can not be printed, any object can be pad printing screen printing ink layer is thick, the printed pattern three-dimensional sense of strong, with the hand can touch the sense of bump, suitable for high-end product surface printing, colour expression is very good, multi-colour overprint more trouble The surface of the product requires a regular flat or curved surface and has certain limitations in the printing range.
　　The principle of pad printing
　　The principle of pad printing is to make a steel plate into a gravure plate by using photographic plate making and then transferring it onto the object to be printed through a special silicone print head, and depending on the material of the product, special inks can be modulated to ensure quality. The process of the pad printing machine is divided into the following four points.
　　1. The ink is evenly covered by the brush on the steel plate.
　　2. The excess ink is scraped off by the ink scraper.
　　3. by the printing head down to the steel plate will be the pattern within the ink stained up.
　　4. By the printing head shift down to the product will be covered with the pattern.
　　Pad printing machine applicable industries: plastic industry, toy industry, glass industry, metal industry, electronic industry, sporting goods, stationery industry, optical industry, ic packaging industry, etc. The pad printing machine is suitable for printing on rulers, pens, spherical objects, doll's eyes, watches, cameras, hair dryer cases, ceramic magnets, medical instruments, rackets, audio tapes, electronic parts, ic, cpu, dram, computer cases, keys, decorative signs, mobile phone cases, etc.
