Recycling problems? Not any more! I nnovations “PCL” separation combination: feeder (right), blade unit (centre) with several replaceable cutting blades, haul-off unit (left). The caterpillar pairs are fitted with standard pads like the ones generally used in profile production. You know the problem. Cassettes of window profiles pile up with sharpened sealing lips or co-extruded top layers since recycling of this material bond has previously been very complex. “PCL” non-cutting separation combination for unmixed RECYCLING of window profiles This new STEIN machine generation solves the problem by moving the profile past specifically arranged stationary blades and cutting off the undesirable material components in the process. A pre-set blade block is locked in place for each profile type in order to reduce the set-up time. You ultimately get an unmixed profile that constitutes about 80% of the original extrudate and can be 100% fed back into the production process after grinding. This new STEIN machine is easy on resources, saves material, storage costs and time-consuming sawing of window profiles and speeds up recycling. A detailed description is available on request. You will be impressed with the functionality! Another new and patented innovation! The non-cutting separated parts on the left and right stand out. The centre picture shows the unmixed profile that can be fed back into the production process.
