Rectangular pipe generally refers to the name of square pipe and rectangular pipe. It is mainly a special steel made of coiled steel. The price of this kind of steel is relatively simple in structure and low in price. It is most used in the structure. Tube, decorative square tube, construction square tube, mechanical square tube, etc. Because the rectangular tube is made of metal, the surface is relatively smooth, and the common labeling methods have poor adhesion and are easy to fall off. Therefore, it brings certain troubles to the identification. As an industrial-grade identification device, the EBS hand-held inkjet printer brings metal products. Concise and efficient application scheme. The compact and exquisite design reflects the high efficiency and convenience of the EBS manual coding machine. It is designed according to ergonomics and has a full grip. Through the body’s built-in LCD touch screen, content editing, parameter adjustment, and printing can be carried out in any workplace. The information is accurate and fast. In order to ensure the adhesion of the handwriting on the surface of the rectangular tube, the EBS portable inkjet printer has special ink, which can still keep the handwriting clean and clear for a long time in the face of wind and rain, whether it is a QR code, barcode, or LOGO. And other content, there will be no fading or blurring, and the practical performance is even better. Different from the hand-held inkjet printers commonly used in the market, EBS attaches great importance to the stability of performance, which reflects the quality of German craftsmen. It adopts innovative solenoid valve nozzles and ruby u200bu200bnozzles. Under different marking environments, the nozzles are free from dust Circumstances such as high temperature, high temperature and other environmental impacts cause clogging and abrasion. The service life is relatively long, and the performance is stable. Therefore, it is not a cost-effective inkjet printer equipment for enterprises. Not only can it meet the coding requirements of the industrial field, the EBS smart inkjet printer has intelligent and diversified functions, a variety of personalized logo combinations, breaking the solidification and singleness, allowing brand information to be displayed and transmitted in depth, WiFi, Bluetooth, Various information transmission methods such as USB are more intuitive and simple, allowing smart signs to be integrated into them.
