PP Hollow Sheets are mainly used for the production of precision mechanical and electrical equipment, daily chemical products construction industry, decoration industry, agricultural products, such as crates, production turnover boxes and so on. Compared with the ordinary Wahleng paper packaging, there is no industrial waste in the production and recycling, and it has no pollution to the ecological environment. It is not only high in packing strength, but also waterproof, oil resistant, corrosion resistant, wear resistant, high temperature resistant, More beautiful, longer life, more convenient recycling.
 
Unit performance characteristics：

The main extruder adopts double shear section screw design, the feed section is water; the plasticizing effect is good, the extrusion efficiency is high. Non-stop fast change network device, with hydraulic workstations, hydraulic push filter plate, without downtime, you can complete the network, improve production efficiency and reduce the generation of waste. Mold flow channel using computer CAD optimization design, material flow, melt distribution more uniform, for the extrusion of high quality sheet provides a guarantee. Traction device with multi-roll traction, trimming device with cutting function, cutting device using pneumatic clamping, automatic fixed length, pneumatic cutting, a high degree of automation, easy to operate.
