Single-stage vs. Two-stage Recycling Machine
Single stage plastic recycling machine Repro-Flex and Two stage plastic recycling machine Repro-Flex Plus both have a cutter-compactor. This cutter-integrated pelletizing system eliminates the necessity of pre-cutting the material, because the cutter-compactor pre-cuts, pre-heats, and mixes the material that will be fed directly into the extruder with a centrifugal force. Compared to the conventional recycling machines, this integrated system does not require a separate crusher, and therefore, eliminates the problem of inconsistent feeding.

The waste material can be fed by a belt conveyor and a nip roller at the same time. The feeding is controlled automatically based on how full the cutter compactor is. The cutter compactor then cuts, dries and compacts the material into a semi-molten condition (just below the agglomeration point), which is optimal for the extrusion process that follows. The cutter compactor then feeds the material directly and consistently into the extruder.

Same cutting and pelletizing system different materials to reprocess
Repro-Flex is able to reprocess PE and PP films, multi-layered film, stretch films, EPE foam, pre-washed film flakes, non-printed and printed (up to 50%) films, others.
Repro-Flex Plus is able to reprocess the same materials as Repro-Flex but can process highly surface printed material, up to 100% of it. This is able thanks to the reposition of the filter and the third degasification.
These pelletizing machines are highly recommended for packing film producers, blown film producers, PP woven producers and professional recycling centers.

Final Product
The recycling machines, Repro-Flex and Repro-Flex Plus, produce high-quality plastic pellets for reprocessing directly into your production line. This is possible thanks to the die-face pelletizing that has an automatic pelletizing speed and blade pressure, producing more uniform-sized pellets.
