Manufacturing Differences: WPC Deck vs WPC Door Frames

Update time : 2021-12-28

The manufacturing of Wood Plastic Composite (WPC) deck and WPC door frames involves combining wood fibers or wood flour with thermoplastic materials. However, there are some differences in the materials and processes used for these two applications

1. Composition:
   • WPC for decking is created by mixing wood flour powder, saw dust, and fiber fillers like pulp, hulls & bamboo with thermoplastics such as polyethylene, polyvinyl chloride, or polypropylene (Surfaces Reporter).
   • WPC door frames, on the other hand, often have additional elements like stabilizing agents, modifiers, and foaming agents. These elements require a strict mixing ratio to ensure the quality and durability of the frames (ekotimber).
2. Material Ratios:
   • The composition for manufacturing WPC doors and frames is often outlined as 70% virgin polymer, 15% wood powder, and 15% additives, although this ratio may vary among different manufacturers (GreenyPlace).
3. Manufacturing Process:
   • Both WPC decks and door frames are produced through a process of mixing the materials evenly, followed by heating and extrusion through mold equipment (OFWPC).
4. Customization:
   • WPC door frames offer a degree of customization. They can be molded into different shapes and sizes according to the requirements, providing room for creating designer doors and frames. This feature is particularly highlighted for door frames where different designs and sizes may be required (ekotimber).
5. Usage:
   • WPC decking is primarily used for outdoor deck floors, railings, fences, landscaping timbers, cladding, and siding. On the other hand, WPC door frames are used for door applications, showing a clear difference in the use of these materials which may also impact their manufacturing process to cater to the specific durability and design requirements of each application (GreenyPlace).
6. Durability and Maintenance:
   • WPC doors are known for their durability, resistance to moisture and termites, and low maintenance requirements, which may influence the materials and additives used in their manufacturing to enhance these properties (ACSLocks).

The manufacturing processes of WPC deck and WPC door frames aim at producing durable, low-maintenance, and environmentally-friendly products. The differences in their manufacturing mainly arise from the distinct applications they are intended for, which require different material compositions, ratios, and possibly different extrusion techniques to meet the desired properties and specifications for each application.
