Plastic pipes are generally extruded and processed in a pipe making machine by a plastic method, and they have been used more and more widely in construction projects. They are mainly used as pipes for tap water supply systems, drainage, exhaust and sewage sanitation pipes for housing construction. , Underground drainage pipe systems, rainwater pipes and threading pipes for wire installation. Because plastic pipes have different pipe diameters, and industry standards, models, batches, specifications, etc. need to be marked on them, traditional manual printing is difficult and easy to print errors. Hand-held inkjet printers can target different pipe diameters. If the diameter of the pipe is small, the machine is equipped with a roller bracket to easily complete various identification tasks. The hand-held inkjet printer can be used for multiple purposes. The exquisite and compact design is more ergonomic. The quick-drying ink can dry quickly on plastic products of various materials without printing, even during transportation. The completeness of the identification information. As a portable inkjet printer, all parts and accessories are industrial grade. They work normally under different temperature and humidity or other harsh production environment. With ruby u200bu200bnozzle, it has the advantages of wear resistance, high temperature resistance and corrosion resistance. The inkjet printer has a wide range. For plastic products with strong plasticity, whether it is on a flat surface, a curved surface, or uneven surface, the handheld inkjet printer can be marked. Considering that it needs to be used in construction sites, outdoor processing plants, production workshops, warehousing and logistics centers, etc., the portable inkjet printer has a battery life of up to 16-50 hours, and can edit and transmit information without a network environment, which is more intelligent and humane.
