In the fast-growing construction and interior decoration industry, innovation and sustainability have become the twin pillars of success. One product that embodies both is the WPC (Wood Plastic Composite) door frame — a modern, eco-friendly alternative to traditional wooden frames.
Behind every high-quality WPC door frame lies an advanced WPC door frame production line, a sophisticated system designed to ensure precision, consistency, and efficiency.
In this comprehensive guide, we’ll explore how Anda Machinery’s WPC Door Frame Production Line can help manufacturers and importers produce top-grade door profiles while reducing costs, saving energy, and contributing to a greener planet.
WPC, short for Wood Plastic Composite, is a hybrid material made from wood fibers or powder, plastic resins (such as PVC, PP, or PE), and additives that enhance stability, color, and durability.
This combination delivers the best of both worlds — the natural look of wood and the high performance of plastic.
Waterproof & moisture-proof: Ideal for humid environments.
Termite & corrosion resistant: Perfect for long-lasting indoor and outdoor applications.
Eco-friendly: Uses recycled plastics and wood waste, reducing environmental impact.
Stable & durable: Less warping, cracking, or fading over time.
Customizable: Supports multiple designs, textures, and colors.
WPC materials are now widely used in door frames, flooring, decking, wall panels, skirting boards, and decorative profiles across residential and commercial construction.
A WPC door frame production line is an integrated system of machines that transforms raw materials (PVC resin, wood powder, CaCO₃, and additives) into finished WPC door frames through an extrusion process.
The production line automates every stage — from material feeding and mixing to extrusion, cooling, cutting, and surface treatment — ensuring consistent quality and efficient output.
Continuous, high-speed production
Precise temperature and pressure control
Easy mold change for various door frame sizes
High automation level with minimal labor
Clean, dust-free environment with optional vacuum feeding system
Anda Machinery’s WPC Door Frame Production Line exemplifies reliability, performance, and energy efficiency — designed for both new and established WPC manufacturers.
A modern WPC door frame extrusion line typically includes the following equipment:
Feeds PVC resin, wood powder, and additives into the mixer automatically.
Options for screw loader or vacuum loader
Ensures dust-free operation and consistent formulation
Mixes all ingredients uniformly under controlled temperature and speed, preparing the raw blend for extrusion.
The core of the production line — where materials are melted, mixed, and extruded.
Twin-screw design (e.g., 65/132 or 80/156) ensures efficient plasticization
Equipped with Siemens motor, ABB inverter, Schneider contactor, Omron temperature controller
Stable temperature and pressure control for high output and product uniformity
Defines the shape and dimensions of the door frame.
High-precision aluminum heating system ensures even heating
