Abstract：Bamboo Plastic Composites (BPCs) are a special compound of bamboo and plastic material. Due to their dimensional stability, BPCs are suitable for indoor and outdoor application as a substitute of traditional wood and plastic materials. Key component in the production process is the twin-screw extruder with intermeshing screws that is specifically designed for processing bamboo fiber composites, and it has the following advantages:interchangeable screw segments, gentle plasticizing and good homogenization of the materials, screw heating and cooling system allowing for temperature control of the melt, high output capacity at low screw speed, controlled degassing of raw materials and color components. The feeding section of the extruder can be filled with enough material and the plasticization effect is better. Special and well designed screw enables raw materials to evenly stay in the extruder. The screws and the barrel are bi-metallically treated, more wearable and anti-corrosive.
