PVC Bamboo Fiber Wall Panel Production line

In interior decoration, eco-friendly composite materials have gained significant market share over traditional wood and stone. Among them, PVC bamboo fiber wall panels stand out for their moisture resistance, flame retardancy, and rapid installation.

PVC Bamboo Fiber Wall Panel Production line

To achieve consistent product density, smooth surface finishes, and high output, setting up a reliable PVC bamboo fiber wall panel production line requires precise control over raw material mixing, extrusion temperatures, and downstream cooling. Engineered for high-duty continuous operation, Kangju Machinery provides turnkey solutions tailored to these exact processing demands.

Components of PVC Bamboo Fiber Wall Panel Production Line:

High-Speed Raw Material Mixer

Before extrusion, PVC resin, bamboo wood powder, light calcium carbonate (CaCO3), heat stabilizers, processing aids, and foaming agents must be thoroughly blended. High-speed mixing machine raises temperatures to around 115℃ – 120℃ to burn off moisture and evenly coat additives onto resin particles.

Conical Twin-Screw Extruder

The core unit of the system is a high-torque conical twin-screw PVC wall panel extrusion line (typically SJSZ-65/132 or SJSZ-80/156 depending on target capacity).

  • Screw Design: Custom screw profiles engineered by Kangju Machinery ensure thorough plasticization at lower melt temperatures, protecting organic bamboo fibers from thermal degradation.
  • Vacuum Degassing: High-efficiency vacuum pumps remove trapped air and residual moisture from the melt to eliminate internal voiding.

Vacuum Calibration & Cooling Table

Once the melt exits the die, it enters a water-cooled vacuum calibrator. Precise vacuum suction holds the outer dimensions tight while internal cooling channels set the final shape without warping.

Haul-Off Unit, Cutter, & Stacker

Caterpillar-type haul-off belts provide stable pulling force synchronized with the extruder speed. An automatic caterpillar cutter or saw cuts the continuous panel to precise commercial lengths (e.g., 2.8m or 3.0m).

Kangju Engineer’s Tips for Stable Daily Operation:

  • Strict Moisture Control: Bamboo powder is highly hygroscopic. Keep its moisture content below 2% before mixing; excess water causes bubbles and structural weakness in extruded panels.
  • Temperature Zone Gradient: Maintain a gradual temperature ramp from the barrel feeding zone (145-155℃) up to the die head (170 – 180℃). Overheating will scorch the bamboo fibers.
  • Formulation Balance: Adjust lubricant ratios (PE wax and stearic acid) carefully. Too little causes high torque and melt fracture; too much leads to internal slippage and poor mechanical strength.

FAQ:

Q1: How are decorative wood grain or marble finishes applied?

A: Surface designs are applied directly after extrusion using an online PUR hot-melt laminating unit supplied by Kangju Machinery to bond PVC film onto the panel.

Q2: What is the average power consumption of the line?

A: While total installed power is 120–150 kW for an SJSZ-65/132 line, actual running power consumption typically averages 60–75% of full capacity.

Q3: What is the service life of the screw and barrel?

A: A quality screw and barrel set operating under normal filler ratios typically lasts 12,000 to 18,000 hours.
