Components of WPC Doors

Raw Materials

WPC Raw Materials

WPC doors are composed of a blend of wood fibers, plastic polymers, and various additives to enhance their properties:

Wood Fibers

Contributing about 50-70% of the WPC composition, wood fibers provide rigidity and a natural appearance. Common sources include recycled wood flour or sawdust.

Wood Fibers WPC Rolangear

These include stabilizers, colorants, and bonding agents that improve UV resistance, color stability, and overall durability.

Steps in WPC Door Production line

Steps in WPC Door Production Rolangear

1. Raw Material Preparation

The production process begins with the precise measurement and mixing of raw materials. This step is crucial to ensure a consistent and high-quality blend.

WPC Raw Material Preparation

Mixing: Wood fibers, plastic granules, and additives are combined in high-capacity mixers. The mixture is heated to allow the plastic to melt WPC Plastic Composite Process  schemes

and encapsulate the wood fibers, creating a homogeneous material.

Formulation: Specific formulations are developed depending on the desired properties of the final product, such as flexibility, hardness, and color.

2. Extrusion

Extrusion is a pivotal stage where the mixed material is shaped into boards.

WPC Extrusion Machine and Processing

Extruder Machine: The mixture is fed into an extruder, a machine that applies heat and pressure to force the material through a mold. This process forms continuous lengths of WPC boards.

Cooling: The extruded boards are immediately cooled using water or air cooling systems to solidify their shape and enhance structural integrity.

3. Cutting and Shaping

Once cooled, the boards are cut and shaped according to specifications.

Cutting: Precision cutting machines ensure that the boards are trimmed to exact dimensions required for door panels.

Shaping: Advanced shaping techniques, including CNC machining, can be employed to create intricate designs and patterns on the door surfaces.

4. Surface Treatment

Surface treatments are applied to enhance the appearance and functionality of the doors.

Sanding: The door surfaces are sanded to achieve a smooth finish.

Coating: Protective coatings, such as laminates or UV-resistant paints, are applied to protect against environmental damage and enhance aesthetics.

5. Assembling

The doors are assembled, including the installation of frames and hardware.

Frames and Hardware: Frames, hinges, locks, and other hardware components are installed. Precision is key to ensuring the doors operate smoothly and fit properly.

Quality Control: Each door undergoes rigorous quality checks to ensure it meets industry standards and customer specifications.

6. Quality Inspection

Final inspection ensures the doors meet all quality and safety standards.

Dimensional Checks: Verify that all dimensions adhere to the specified tolerances.

Surface Inspection: Check for any surface defects, such as scratches or uneven coatings.

Performance Testing: Doors are tested for durability, impact resistance, and functionality.

Benefits of WPC Doors

Benefits of WPC Doors - Rolangear

Water and Moisture Resistance

WPC doors are highly resistant to water and moisture, making them ideal for humid environments like bathrooms and kitchens. This resistance prevents warping, swelling, and degradation that typically affect wooden doors.

Durability and Longevity

Combining the strengths of wood and plastic, WPC doors are incredibly durable. They withstand physical impacts, resist scratches, and maintain their structural integrity over time. This durability translates to a longer lifespan and lower maintenance costs.

Environmentally Friendly

WPC doors are eco-friendly, utilizing recycled wood and plastic materials. This reduces waste and the demand for virgin resources. Additionally, they do not contain harmful chemicals, ensuring a safer indoor environment.

Easy Maintenance

The smooth, coated surfaces of WPC doors make them easy to clean and maintain. They resist stains and can be wiped down with a damp cloth, reducing the need for harsh cleaning agents.
