One-Step Plastic Recycling Machine HNT-V

Combines Cutting, Extrusion and Pelletizing

Polystar Machinery Co., Ltd, Tainan, Taiwan, presents its high-efficiency, one-step plastic recycling machine HNT-V designed for the reprocessing of polyethylene (HDPE, LDPE, LLDPE) and polypropylene flexible packaging material, printed and non-printed. The HNT-V plastic recycling machine combines cutting, extrusion and pelletizing into one compact and efficient recycling line. The cutter compactor of the recycling machine prepares (pre-conditions) the material into an ideal condition for the extrusion process and feed the material directly into the extruder with a centrifugal force. Compared to conventional recycling machines, this integrated system does not require a separate crusher, and therefore, eliminates the problem of inconsistent feeding (over-feeding or insufficient feeding).

In addition to in-house (post-industrial) film waste, the system is also able to process washed flakes, scraps and regrind (pre-crushed rigid plastic waste from injection and extrusion). This equipment is highly recommended for packaging film producers of commercial bags, garbage bags, agricultural films, food packaging, shrink and stretch films, as well as producers in the woven industry of PP woven bags, jumbo bags, tapes and yarns. Other types of material such as PS sheet, PE and PS foam, PE net, EVA, PP mixed with PU are also applicable on this machine.

The stable material feeding together with the hot die face pelletizer produce round-shaped, uniformed size pellets (figure: Polystar)

The pellets produced by the recycling machine can be put directly back into the production line, in most cases for blown film or pipe extrusion processes. On average, post-industrial waste makes up 5% or more of the entire production line, making in-house recycling very important nowadays as it can significantly reduce the cost of raw/virgin material purchasing. The plastic pellets produced from in-house waste are almost like-new and can be re-used for producing high quality plastic products once again.

The HNT-V is also designed to work with washed, post-consumer and used agricultural film. The cutter compactor, which generates frictional heat during the compacting process, helps to further dry and remove the water moisture from the washed film flakes (processed first by the washing lines). The recycled pellets can be used again in extrusion process, whether 100% (such as garbage bag, LDPE pipe production and etc) or as part of the mixture to reduce raw material cost. The pellets quality can also be improved by direct dosing of masterbatch and additives.

The integration of the cutter compactor and extruder ensures extremely fast and stable feeding, the tangentially connected extruder is continuously filled with pre-compacted material. This results in a much higher production output.
