When choosing a WPC door board extrusion line manufacturer, many buyers focus on brochures, quotations, or promises. However, the real difference between suppliers lies inside the factory.
As a direct source manufacturer, KINGSHINE believes transparency builds trust. In this article, we take you inside the KINGSHINE factory to show how WPC door board extrusion lines are designed, manufactured, tested, and delivered.
KINGSHINE specializes in WPC profile extrusion solutions, with a strong focus on:
WPC door board extrusion lines
WPC door frame extrusion lines
Turnkey WPC door manufacturing solutions
Unlike trading companies, we control the entire manufacturing process—from design to final testing.
Every WPC door extrusion project starts with engineering design, not sales.
Target door board size and structure
Required output capacity
Raw material formulation
Local power and factory conditions
This ensures each extrusion line is custom-built, not a one-size-fits-all solution.
The screw is the core of WPC extrusion performance.
At KINGSHINE, we:
Design WPC-specific screw geometry
Machine screws and barrels in-house
Apply wear-resistant treatments
This guarantees:
Stable plasticizing

Better adaptability to wood powder
Few suppliers can offer this level of control.
Extrusion molds directly determine door board quality.
CNC machining for flow channel accuracy
