The DY003 high-speed tri-sided printers is a new generation of pencil printing device (patented) which is used generally, efficiently, reliably. The printer is mainly used to print trademarks on triangular and hexagonal pencils or other shapes, as well as round pencils (for different shapes of shaft, only replacement of the corresponding baseboard is needed). All materials for main parts of body are made of quality carbon steel to ensure stable running. The printer has novel appearance, compact and flexible configuration, and it is easily operated, adjusted, fixed. Because of quality bearing as transmitting parts, no lubricant is needed by the device during production (except regular replacement), it is the first choice for pencil manufactures to print their brands. As a result of use of variable stepless speed, feeding speed can be chosen according to the actual need of customers.
