Pamex 2023: Rotometal antifriction cylinder at UV Graphics stall

According to the company, the innovative approach of Rotometal allowed to create the antifriction print cylinder. The applied solution facilitates and speeds up work at the production plant level. It offers less effort when removing tape and foams with no adhesive residue left on the cylinder.

A breakthrough solution that optimises the friction properties and the smoothness of the coating thanks to the use of the Polymeroxid-matrix, which is cross-linked with a special LF4 polymer throughout its thickness.

The use of this innovative method in the production of printing tools made it possible to obtain exceptional surface smoothness while maintaining a high hardness of about 450 HV, depending on the aluminum alloy used. The antifriction coating used in the Rotometal printing cylinders also gives the possibility of better protection against damage.

“The pioneering solution enabled us to manufacture tools with unprecedented functional properties, which, by combining high durability and optimal adhesion, distinguish us from other suppliers,” Bhupesh Tilwani of Rotometal said.

“Before being dispatched to the customer, each product is checked by our quality control department for compliance with the technical drawing and accepted in-house standards — a structured inspection scheme.”

The advantages:  

• Completely new Polymeroxid-matrix which is spread over the entire thickness of the cylinder
• Material can be removed in one piece; trouble-free
• Removal of tapes and foams does not require a lot of force thanks to the technologies used
• Fast belt change without adhesive residue on the cylinder surface
• High surface smoothness
• Coating hardness around 450HV
• Optimal adhesion of the foam to the glue; holds well during printing and is easy to disassemble
• Antifriction coating provides better protection against scratches
• Possibility of making lines along and transverse lines to facilitate the assembly of the dies
