How to Choose the Right WPC Door Board Extrusion Line for Your Factory

Introduction: Choosing the Right Line Matters More Than You Think

Investing in a WPC door board extrusion line is not just about buying a machine—it is a long-term production decision that affects product quality, operating cost, and factory scalability.

Many door manufacturers make mistakes by choosing equipment based only on price or supplier promises. As a direct WPC extrusion line manufacturer, KINGSHINE helps customers worldwide select the right configuration, not just the cheapest option.

This guide walks you through how to choose the right WPC door board extrusion line for your factory, step by step.

1. Define Your Target Door Board Product Clearly

Before selecting any machine, you must clearly define what kind of WPC door board you plan to produce.

Key questions to ask:

• Hollow door board or solid door board?

• Door board width and thickness?

• PVC-based or PE-based WPC?

• Interior doors or exterior doors?

Different products require different extruders, molds, and cooling systems. KINGSHINE customizes each line based on your final door design.

2. Choose the Right Output Capacity for Your Market

Output capacity directly impacts both investment and production efficiency.

Common capacity selections:

• 150–200 kg/h: Entry-level or trial production

• 250–300 kg/h: Standard commercial production

• 350–400 kg/h: Large-scale door manufacturing

Oversized capacity increases cost unnecessarily, while undersized capacity limits growth. KINGSHINE helps customers match real market demand with the correct capacity.

3. Select the Correct Extruder Type and Screw Design

The extruder is the heart of the WPC door board extrusion line.

Main options:

• Conical twin-screw extruder (common for PVC-based WPC)

• Parallel twin-screw extruder (high-output applications)

A professional WPC extrusion line must use WPC-specific screw geometry to ensure:

• Stable plasticizing

• Uniform wood dispersion

• Reduced material degradation

KINGSHINE designs and machines screws in-house to ensure optimal performance.

4. Mold Design: More Important Than Most Buyers Realize

Many buyers underestimate the importance of the extrusion mold.

Mold selection factors:

• Hollow structure complexity

• Flow channel balance

• Steel material and heat treatment

• Ease of maintenance

A poorly designed mold leads to surface defects, deformation, and unstable production. KINGSHINE manufactures molds internally for dimensional accuracy and long-term stability.

5. Cooling, Calibration, and Pulling System Matching

A stable extrusion line depends on perfect system matching.

Key components include:

• Vacuum calibration table

• Cooling water system

• Haul-off (pulling) machine

Mismatch between extrusion speed and pulling force is a common cause of deformation. KINGSHINE uses synchronized control systems to ensure consistent board quality.

6. Automation Level and Labor Cost Considerations

Automation directly affects long-term operating cost.

Automation options:

• Manual feeding and cutting

• Automatic feeding system

• Online cutting

• Automatic stacking

Factories in regions with rising labor costs benefit greatly from higher automation. KINGSHINE offers scalable automation solutions based on your budget.

7. Raw Material Compatibility and Formulation Support

Not all extrusion lines handle materials equally well.

A reliable WPC door board extrusion line should process:

• Different wood powder ratios

• Recycled materials

• Various additive systems

KINGSHINE provides material formulation guidance and process tuning, reducing production risk and startup time.

8. Installation, Training, and Technical Support

Machine performance depends heavily on correct installation and operation.

When choosing a supplier, evaluate:

• Installation support availability

• Operator training programs

• Process optimization services

• Spare parts response time

As a source factory, KINGSHINE offers complete technical support from installation to mass production.

9. Total Cost of Ownership vs Initial Price

The cheapest machine often becomes the most expensive in the long run.

Consider:

• Energy consumption

• Maintenance frequency

• Downtime risk

• Equipment lifespan

Choosing the right extrusion line means focusing on total cost of ownership, not just the purchase price.
