Q&A
Q: Do you support non-standard size customization? **
A: Yes! Provide length, outer diameter, coating thickness and other parameters customized services.
Q: What is the difference between chrome-plated roller and ordinary steel roller? **
A: Chrome-plated roller surface hardness is higher, wear resistance and ink transfer performance is excellent, long-term use cost is lower.
Q: How to extend the life of chrome plating rollers? **
A: It is recommended to regularly clean the residual ink on the surface to avoid scratching by hard objects, and return to the factory every 2 years to test the coating status.
