Carbon structural steel is mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, and unimportant mechanical parts and general welded parts that do not require heat treatment. According to national standards, the corresponding numbers and companies need to be marked. Name and other information. It is common to use label paper to stick to the metal surface, but the storage period is short, it is easy to fall off, and the handwriting fades in the long-term outdoor environment, and the practicability is not strong. In comparison, the EBS handheld inkjet printer has the ability to print on carbon structural steel. Several major advantages, such as portability, high efficiency, long-lasting, and high cost performance. In terms of appearance, the EBS handheld inkjet printer adopts an ergonomic design. On the premise of having a good grip, combined with long battery life, it is easy to carry and print in any environment. The LCD comes with the body. The touch screen can quickly complete content editing and parameter adjustment on site. The rich scalability gives the EBS smart inkjet printer a wider range of applications. It supports WiFi, Bluetooth, USB and other transmission methods, and can realize real-time printing of dynamic data, whether it is a QR code, barcode, pattern, etc., It can be integrated with the industrial Internet of Things, so that the logo is not limited, and the interpretation can be freely printed. The EBS manual inkjet printer demonstrates the spirit of German craftsmanship. It adopts innovative solenoid valve nozzles and ruby u200bu200bnozzles. It has outstanding performance in wear resistance, corrosion resistance and dust resistance, and can adapt to stable and smooth operation in various harsh environments. The performance of marking tasks far exceeds that of the same type of coding equipment. The wide range of application performance interprets the characteristics of the EBS portable inkjet printer. It is not affected by the environment and material. It has multiple functions. It can print on flat, curved, curved, or concave, and it will not fade for a long time. Fuzzy, shifting, simple ink cartridge replacement method, convenient and more efficient.
