Satin

The company has developed a particularly effective satin-finishing technique, able to satisfy any finish requirement in terms both of quality and of repeatability. Machining and surface roughness parameters are always filed according to the specifications of the Company Quality System. Since the roughness of the finish on the cylinder is not always strictly connected to the visual properties of the end product, an extensive database of knowledge has been created from which to identify the real needs of the Client as quickly as possible. Typical applications:

• embossing rollers
• haul-off and stretch rollers
• calenders in plastic laminate manufacturing systems
• chill roll

Superfinishing

The combination of superfinishing and CHROMLIGHT electrodeposition techniques is able to guarantee a surface finish of visual and geometric perfection. Profilograph measurement guarantees a Ra roughness value equal to or less than 0.002 um, a parameter suitably tested and certified for the benefit of the Client. Superfinishing is carried out in such a way as to guarantee even the closest of geometric tolerances: errors of concentricity and linearity are in fact less than 0.002 mm. This conforms to the Company Quality System procedures applicable to the "SF" (SuperFinishing) machining code, a reference code indicated on all accounting documents. Superfinishing technology is mainly used by our Clients for the following applications:

• bonding cylinders
• calender polisher cylinders for plastic laminates (polycarbonate, polymethylmethacrylate, etc…)
• spreader machine cylinders
• flat extrusion head die lips
