Surfaces
In addition to the detailed design and manufacturing of the rolls, the surface quality has a huge effect on the roll. We co-operate with well-known European partners who are experts in this area. Our repertoire includes:
• Superfinish polished surfaces
• Electroplated matt or textured surfaces for extrusion coating.
• Embossing structures, etching-patterns
• Plasma-coated rolls
• Rubber-coated surfaces.
Due to our partnerships we are able to offer a complete product range in roll-technology to achieve customers’ demands or to develop new solutions for non-standard applications.
We will assist you with pleasure in choosing a suitable surface for your application.
Beside others our delivery program encloses the following surfaces:
