Pad printer A printing equipment for plastics, toys, glass, metal, ceramics, electronics, IC seal. Pad printing is an indirect printing technology may be concave plastic head, has become a variety of surfaces and decorative printing a primary method. Pad printing machine operation Etching the plate ( steel ) coated with ink method : etching plate inking in a lot of ways . First, the ink is sprayed on the etched board with a retractable blade and the excess ink is scraped off . At this time , stay in the erosion area of volatilization of the solvent in the ink and the surface of the gel is formed , and then etching down to the first plastic panel , suction ink. Suck ink and printed products: plastic head suction plate etching ink big department increased after this time, this layer of ink and a volatile sector , leaving a sector not dried ink surface is more conducive to the object to be printed with the rubber head close combined . Plastic head shape to be able to produce a rolling action to drain the surface of the ink etched plates with excess air . In the production process of the ink and the plastic head The ideal situation is that all the ink etching the board are all transferred to the object to be printed , in the production process ( approximately 10 microns or 0.01 mm thick, adhesion of the ink is transferred to the matrix ) plastic head printing easily affected by air temperature, static size effect . If the transfer from the etching plate plastic, the entire process to the substrate , the evaporation rate and the dissolution rate control in an equilibrium state is good , it is considered a successful printing . If evaporate too quickly , even before the ink is absorbed dry . If evaporation is too slow, has not yet formed gel ink surface , easy to make plastic head and matrix attachment. Pad printing machine direction toward automation is the industry consensus. This is to improve production efficiency, reduce costs necessary way , but also printing technology from labor-intensive industries to technology -intensive industries into the necessary requirements. Currently, the high degree of automation is relatively common printing machine rotary printing machine delivered its printing process is fully automated . Affected by the degree of automation , the vast majority of companies consider the quality of the printing process in the countermeasures issues are still imperfections, even if such a printing machine, in order to complete a truly automated printing but also faces many challenges. Universal automatic pad printing machine is relatively rare, but specific products targeted automatic pad printing machines still have a lot of surprises. For example , printing the CD automatic printing machine, automatic printing bottle cap printing machines. Pad printing machine automation essentially means that the product conveyor automation , as part of the change is small pad printing . A variety of information on new technologies broadened our horizons, other printing technologies penetrate , let us generate new inspiration, customer requirements will inspire passion printer manufacturer . Pad printing machine technology since its inception, especially after entering the domestic market , with regard to its obvious advantages are more and more business concerns . It is combined with screen printing technology , co-development of the printing market situation. From the traditional labor-intensive to technology-intensive gradually forward. This is a trend to adapt to world development . Currently , printing machine printing processes are constantly improved and perfected . Ink for printing technology is essential . Today, the emergence of closed ink can be said printing machine printing technology , a new progress . First, it is energy-saving , environmental protection, because it saves the amount of ink , while health workers also enjoy a more comfortable environment . Second, it saves time and effort , because the long-term stability of the viscosity of the ink , it eliminates the cleaning cartridge after printing , squeegee trouble. In addition, during mass production operation, the use of closed ink is easy to do . It combines the use of staff into consideration the more factor that makes the production efficiency and quality of the further improved. Currently printing process is also to update the field forward. In order to more effectively put into production , printing technology is gradually completed online production, the printing machine and the entire production and operation of organically combined to form a complete and unified link. Currently printing printing technology is gradually moving towards automation , high-precision systems not only through the quality of printing that accuracy , it is adapted to the needs of mass production . In addition, the pad printing technology is gradually and production environment , consumption and maintenance products form a complete part. Now with the pad printing machine printing trade descriptions , trademarks and other patterns more and more manufacturers , and exactly why they are willing to choose printing machines as their choice of whether the printing machine 's competitiveness in the wrong ? In fact ,pad printing machine printing equipment does have many of the same advantages you do not . First, a printing machine can do up to 12 chromatic called multicolor overprint , one will be able to print all the products , thus improving efficiency and saving money , even just a small construction firm can afford these costs , compared to similar products multicolor screen printing machine overprint becomes expensive it. Secondly, it compared the characteristics of screen printing machine ,pad printing machine ink layer is very thin, which means it is easy to leave marks on the surface of any product , whether it is flat, curved or wavy surface , can be a perfect copy printed pattern However screen printing machine in this respect is very complicated, flat screen printing machine can print screen , if you want to print the application surface and will face another wave surface screen printing machine up . Moreover , printing machines with very good color performance and printability , although the pattern printed silk screen technology three-dimensional sense of strong, rugged touch can feel the real sense , but if the types of products than printed ,pad printing machine can definitely be called a panacea, either plastic or metal , whether it is sports or glass, it is a piece of cake for the pad printing machine . Such formal printing machine performance, low price point was completely special completely adapted to this highly developed commercial material society , became the first choice of contemporary manufacturers , such as Ningbo and Shanghai printing machine printing machine is moved printer's producing provinces for the entire society with high efficiency machinery. Seal oil cup pad printer Open type ink tank with respect to an alternative model is to seal the ink tank. Served in a flip ink container, Through the pressure plate in contact with the etching. The container scraper remove ink from the etching plate. Since the container is sealed, so that the solvent does not evaporate, the ink remained stable conditions, to make the machine cycle longer. Although these models seem to solve the problem of stability of the ink, but how to properly deploy the ink is still very important issue, many factors will affect the volatile solvent. Press * for must be quite serious and responsible,Otherwise it will wear etched plates and the container will put ink sprayed outside the etched plate. And for an ink tank is expensive. Such systems are increasingly used in automated production lines. Pad printing technology theory * define the use of soft Pad printing plate transfers the ink on the image area to the substrate in the printing machinery. Indirect printing machine printing is an important one . * Power Source: Pad printing machine main action can be divided into: plastic head dipped under the pressure of the ink on the pad plate and elevation ; rubber head moves to the upper substrate ; printing plastic head under the pressure elevation after printing . Three kinds of action leading to the different ways to control printing machine determines the three basic categories : Manual pad printing machine, three kinds of actions are controlled manually . Is the simplest printing machines, only complete small batch production orders and product sampling tasks. Electric pad printing machine, three kinds of actions are motor driven and controlled. Printing speed, but the printing pressure is small, only a smaller area to complete the production date of printing and bar code products . Pneumatic pad printing machine, three kinds of actions are digital circuit control pneumatic components to complete. Printing speed, printing pressure, high degree of automation , is currently the most common printing machines . |
