When aluminum profile comes out of the extruder,the temperature is about 550℃ and not many materials can stand such high temperature for long time.PBO fiber is the kind of material that can resist high temperature up to 600℃,The PBO roller composed of PBO is ideal to use at extrusion initial area and beginning of the run-out table.It is the density of the PBO layer enables the rollers to work continuously under temperature 600℃,and at the same time to stand the abrasion from different shapes of the profile.Super high temp. resistance felt roller,Suitable for use before fly cut.Effectively improve the scratch mark made by the graphite. (Ultra-high Temp. Zone)
Calm-brand seamless roller series is specially developed for the customers who have a high requirment for surface.Advantages of Calm-brand roller:It resists to rasing,unevenness,scaling,aluminum pollution and other defects.With smooth surface,the product adopts advanced new technology and is more surable and cost-effective.It is especially suitable for the production of high-quality aluminum products with electrophoretic or polished surface.
