Wood Plastic pelletizer

Wood Plastic

Amidst the wave of green building materials emphasizing both environmental protection and high performance, WPC (Wood-Plastic Composites) is gradually emerging as an ideal alternative to traditional wood and pure plastic. The wood plastic pelletizer is precisely designed to craft high-end wood-plastic profiles for you, with a surface hardness typically 2-5 times that of ordinary wood, offering durability and stability.

Types Of WPC

Common ones include:

Zero Backlash & High Repeatability — precision-ground assemblies ensure consistent, accurate positioning every time.

  • Wood fiber + polyethylene (PE): door panels, outdoor garden flooring, etc
  • Wood fiber + Polyvinyl chloride (PVC): door panels, outdoor garden flooring, outdoor fencing, etc

In terms of biodegradability:

  • PLA+ plant starch: plates, cutlery, and other tableware

In plant powder filling:

  • PP + starch or other plant powders: disposable food containers, outdoor tableware, etc

WPC Extrusion Process

Core process:

  • The melting temperature of PP/HDPE exceeds 170°C, so the side feeding method must be used to feed the wood fibers.
  • Due to the moisture absorption of wood powder, it needs to be dried before entering the hopper to avoid bubbles or uneven mixing.

PP PE + wood powder:

  • Equipment selection: Parallel twin screw, L/D 48~56:1 (determined according to the proportion of wood powder).
  • Basic formula: PP/PE compounded with wood fiber (up to 65% ratio) + color masterbatch + additives (lubricants, UV masterbatch, antioxidants, etc.)

PVC + wood powder:

  • Equipment selection: double-stage granulation (twin-screw L/D: 36~48:1 + single-screw L/D 9:1)
  • The material used for PVC window profiles does not need to be granulated; it simply needs to be cooled and crushed into powder. Through twin-screw compounding and conical twin-screw extrusion, it can be directly extruded into sheets and other forms.
  • Basic formula: PVC combined with wood fiber + color masterbatch + additives (lubricant, UV masterbatch, antioxidant, etc.)
