The pipe industry has a long history in the application of the coding and marking industry. Since 2000, various pipe factories have started to use printing equipment, printing obvious specifications and models, manufacturer names, LOGO patterns, etc. on the pipes themselves. information. There are very few pipe manufacturers who have just started to use inkjet printers, because they are expensive, and most of the markets are imported small-character inkjet printers. The later use cost, especially the cost of ink and solvent, is relatively high, which is caused by various reasons. At that time, tube mills used more printing wheels. The printing wheel consumables are cheap, and you can buy a large bucket of ink for a few hundred yuan. The disadvantage is that a large number of abrasive tools need to be prepared and replaced when printing. The content is printed on the wheel in advance, which is very inconvenient. In addition, the printing effect is not very satisfactory. There is a certain gap between the dot matrix font and the small character inkjet printer. After 2009, with the improvement of domestic inkjet printer Ru0026D and manufacturing process, after several years of testing, stability and price have been better competitive, and the scope of use is not limited to some simple manufacturing industries. From the food, beverage, electronics industry to the building materials industry, there have been considerable application developments. In the past few years, the application of labeling technology has gradually penetrated into every corner, especially in the industrial field, the application range has become wider and wider, and the complexity of the application has greatly increased, making the label an indispensable and important part of the production of various industries. : The production of plastic pipes, profiles, aluminum (steel) plastic composite pipes and other plastic extrusion materials is no exception. As the pipe industry with the largest number of stations in the plastics industry, the use of inkjet printers is even more surprising. The sales volume is increasing year by year, and there is a very obvious rising trend. Most manufacturers have begun to use inkjet printers to print production dates, batch numbers, brands, and specifications.
