What is WPC Door?

WPC door is manufactured through a molding process, it combines the excellent properties of wood and plastic, and the products produced achieve the effect of truly imitating wood. Since the raw materials used and the production process do not use glue, it will not produce harmful substances such as formaldehyde, benzene, ammonia, trichlorethylene, etc. It is a new green and environmentally friendly material that replaces traditional wood.

What is WPC door made of?

1. PVC resin

2. Calcium carbonate

3. Wood powder

4. Stablizer

5. PE Wax

6. Stearic acid

7. Foaming regulator

8. Foaming agent

9. CPE

10. DOP

WPC doors are made of ultra-fine wood powder and PVC resin mixed through a molding process. Because the main materials of WPC doors are PVC resin and high-quality wood powder, WPC doors have the advantages of both wood and plastic. The imitation wood effect is so realistic that it is difficult to distinguish. The biggest feature of WPC doors is environmental protection. It is a new green and environmentally friendly material to replace traditional wood. The WPC door formula system is equipped with a certain proportion of auxiliary materials, adding stabilizers, foaming agents, modifiers, etc., and the various ingredients are mixed in strict proportions to effectively ensure the product quality of the foam board.

WPC Door Production Line

1. Mixing materials

Put the PVC resin powder, calcium carbonate, wood powder, and recycled PVC into the heating and cooling mixer according to the formula ratio, and the additives weighing machine automatically adds the additives, stir for about 30 minutes, and send the evenly mixed mixture to the conveyor belt and enter the internal mixer for heating and mixing.

2. Extruding WPC door boards

The mixed material powders be transferred into a conical twin screw extrusion machine, The temperature is about 170°C. Finally, the raw material is cooled and refined, which will be produced into the door board/door frame. Because the production of WPC  foam doors has high requirements for foam extrusion equipment, a high-torque twin-screw extruder was used, and the screw, barrel, and other components were modified to adapt to the skinning and surface damage of wood-plastic internal and external surfaces. Foams evenly to avoid wood powder carbonization and other phenomena.

3. Sanding

sand the door panel surface and four sides, make it more smooth for lamination. The PVC WPC hollow door panel sanding machine not only improves the processing quality of the sanding machine, saves manpower and improves processing efficiency, but also improves the convenience of waste cleaning.

4. Surface treatment

The surface treatment includes hot stamping, lamination or vacuum pressing（chose one from three）

Hot stamping technology takes the lead in using thermal transfer printing technology to transfer various decerative patterns on the extruded sheets, so that the products have a variety of high-grade tree species wood grains and colors.

The WPC door lamination machine covers the PVC film on the surface of the door panel. It is easy to operate and adjust. The transmission system adopts variable frequency stepless speed regulation, which saves energy and reduces consumption. The speed changes smoothly and is suitable for different work needs. The fully imported silicone conveying wheel and molding pressure wheel are wear-resistant, oil-resistant, heat-resistant, and the cleaning of residual glue is simple and convenient. There is an auxiliary heating device, which is suitable for the climate temperature in different regions.

The vacuum pressing machine uses vacuum to bond the PVC film to the PVC WPC board after gluing, so as to cover various types of decorative parts such as flat surface, concave and convex grooves, curved edges, hollow carvings, etc., so as to achieve decorative shape and obtain beautiful colors; in addition, vacuum forming can achieve one-time molding, so it can greatly reduce costs in production.

5. Quality Control

After the WPC door is manufactured, it goes through a quality control process to ensure that each board meets the required standards.
