WPC hollow door panel is made of Wood plastic is a composite material and wood powder, it is environmental material and can be recycled and used repeatedly with the low cost of the raw material.

Wood-plastic composite products advantages

• Environmentalism
• Waterproof, dampproof, rotproof.
• Reasonable structure and high intensity
• Splicing structure, timesaving and laborsaving
• Finer heat preservation and sound insulation
• Stable quality and economical cost.

Wood-plastic composite door production Process

A. Technical Routes

Wood Power + PVC Resin + Assistant Agent → Extrusion → Forming → Printing on
Surface → Installation → Packaging

B.Flow Chart

C. Technical introduction
Firstly put PVC, wood powder, compounding, and another assistant agent into high-speed mixer. After mixing
symmetrically and then deeding into the hopper. At the same time fix extruder temperature in advance and keep it.
Thirdly melting and plasticizing resin by specially designed screw symmetrically, and transporting into vacuum
forming system, and cooled. Then put into the draw-off system and reaching an automatic cutting system according to a fixed length, and cutting automatically to the stacker. Finally, pack the qualified product into storage. The defective products and edges will be recycled by crusher and flour milling.

D. Main Material

•  PVC
• Wood powder
• Plugging compound
• Assistant agent
