Quality & Service

Quality Roller, especially the ceramic roller is an important integral part of wear-resisting paper, flooring paper, CCL. industry. Its advantages are: good wear resistance, high strength, small thermal expansion, good stability and high dimensional accuracy. Similarly, mirror rollers are widely used in optical film, CCL. and lithium battery coating industries. The rule is that the more smooth and precise of roller surface, the better products can be produced. We are trying best to gain the smallest tolerance and best roller surface.

Various high precision and advanced equipment used in roller manufacturing by Woltty include turning, welding, grinding, polishing, balance, center-less grinding, cylindrical grinding, etc. Domestic high-quality supporting technologies include heat treatment, surface treatment, hard chromium plating, ceramic spraying, laser engraving and so on.
