On train tracks, switch pillows marked with numbers and letters can be seen everywhere. So what do these numbers and letters mean? In fact, concrete turnout sleepers are special sleepers used on railway turnouts to make the track elastic even and improve the stability of the track. They are mainly used at the traction point of the turnout. The turnout electrical and electrical conversion rods can be placed in the sleepers, which is conducive to large-scale machine maintenance operations. Nowadays, with the increasingly stringent product specifications, each turnout sleeper needs to be marked with the relevant serial number and batch number, so numbers and letters identification will appear.

Which kind of inkjet printer should be selected to realize the identification of concrete fork sleepers is a focus of attention for various production companies, because concrete fork sleepers are usually completed by prefabrication, and the finished product has the characteristics of large size and poor mobility. Comprehensive consideration of the product itself is given to characteristics, so it is generally recommended that production companies choose a handheld inkjet printer that can be carried around, is simple to operate, and has a smart body.

The nozzle of the Shicai handheld inkjet printer is resistant to wear and corrosion, and the principle of on-demand ink supply printing greatly reduces the failure rate of the handheld inkjet printer. Rich communication functions and user-friendly operating interface allow users to have a better user experience. The spray printing content is rich and can be combined according to needs through various different contents such as graphic patterns, LOGO, QR codes, bar codes, Chinese and English, numbers, etc., so that each concrete fork pillow has a unique identity. The Zhicai handheld inkjet printer combines high-adhesion ink. When faced with wind and rain for a long time, the printed content will not shift or fade, and will remain neat and standardized, and clearly visible. In addition to its successful application in the field of prefabricated parts, the Color Handheld Printer can also be used in industries such as steel plates, steel pipes, and woven bag packaging.
