PVC Wood Co-extrusion Door Frame Machine

Description

Yongte PVC Wood Co-extrusion Door Frame Machine is specifically designed and optimized for the mass production of solid WPC door frames. To overcome the disadvantages of traditional WPC solid door frames, such as heavy weight, high cost, easy deformation, and weak nail/screw holding, we have developed a PVC WPC layer + Wood/LVL/MDF core co-extrusion technology for producing low-cost WPC solid door frames in one step. This innovative production solution integrates material structure innovation with automated processing technology, laying a solid foundation for high-efficiency, low-cost manufacturing of high-performance solid WPC door frames.

The inner core of the solid WPC door profile can be LVL wood, MDF profile, aluminum profile, or steel post. The outer layer can be a WPC layer or PVC layer, with a thickness of 4-5 mm being sufficient. This flexible structural design combines the advantages of different materials: the outer WPC/PVC layer provides good waterproof, moisture-proof and anti-corrosion properties, while the inner core material supplies sufficient structural strength and supporting performance, perfectly balancing product performance and manufacturing cost.

At the same time, this co-extrusion structure inherits the appearance characteristics of traditional WPC profiles, which can be directly processed by nailing, planing and painting, matching the conventional installation and subsequent processing technology of finished door products, and no additional adjustment of the existing production line of downstream manufacturers is required. Relying on the mature co-extrusion process and stable equipment configuration, this production line can maintain long-time continuous and stable operation, helping enterprises achieve high-efficiency, high-quality mass production of cost-effective solid WPC door frames.

This PVC Wood Co-extrusion Door Frame Machine integrates co-extrusion processing technology, enabling one-step forming of the wood/LVL/MDF core base and functional co-extrusion layer, effectively simplifying the production process and reducing manual intervention and processing loss. Compared with traditional separate processing and assembly processes, it significantly improves production efficiency while stabilizing product dimensional accuracy to meet the standardized size requirements of solid WPC door frames for downstream door product manufacturing. At the same time, the production line supports flexible adjustment of formula and process parameters, which can match different functional requirements of finished door frames to help manufacturers control production costs while ensuring product performance.

Technical Parameters

The main technical indicators of the Yongte PVC Wood Co-extrusion Door Frame Machine are as follows:

All core components of the PVC Wood Co-extrusion Door Frame Machine adopt brand standard configurations, and the specific parameter indicators can be adjusted and customized according to the actual production scale and product requirements of the customer.

Advantages:

1, Lower production cost:

Compared with the traditional solid WPC door frame production mode that uses all WPC materials as raw materials, this co-extrusion structure greatly reduces the dosage of high-cost WPC or PVC materials, and replaces the main structural part with cheaper wood/LVL/MDF core materials. This raw material structure adjustment directly cuts down the raw material cost per unit product, and the one-step forming process also reduces the extra cost brought by multiple processing and secondary transfer. What's more, the stable and efficient continuous production of the equipment reduces the defective rate in the production process, further helping manufacturers control production cost from multiple links.

2, Stable production, avoiding deformation:

For a full WPC door frame, foaming occurs inside the profile, and it is difficult to ensure uniform foaming. As a result, many manufacturers encounter product deformation problems. Even when using the same machine and the same formula, the product quality can vary, making it difficult to maintain consistent production and quality. The production defective rate is therefore high.

For the WPC+wood door frame, the inner core size is fixed and is fed into the extrusion line stably and continuously, so it is very easy for machine operators to control the product quality and forming dimensions. The 4-5 mm outer WPC layer is also easy to control with the die and calibrators. As a result, the production defective rate is very low.

3,Higher production speed:

For the Full WPC door frame, it is difficult to cool the inside completely. Even if the length of the calibrator and water tank is increased, the production speed is still very limited to 0.3-0.5 m/min because of the large product thickness and high internal heat. Moreover, the product may deform after production due to the residual heat inside that cannot be fully removed in the extrusion line.

For the WPC+wood door frame, the inner LVL core is at normal temperature and only needs surface heating before being fed into the extrusion line. Since the WPC layer is only 4-5 mm thick, the complete product can be easily cooled by the calibrators and water tank. Therefore, the production speed can reach 0.5-0.8 m/min, and the product can be fully cooled in the extrusion line, avoiding deformation after production.

4, Better nail/screw holding strength, high strength, and high toughness

For the Full WPC door frame, due to its inner foaming and the fact that it is made of PVC and wood composite (wood content is less than 20%), it suffers from weak nail/screw holding. In particular, because of its heavy weight, the door frame may loosen after a period of use.

For the WPC+wood door frame, the inner core is wood/LVL/MDF, which offers high strength, high toughness, resistance to fatigue failure caused by periodic stress, and high nail/screw holding strength. As a result, the nail/screw holding strength of the WPC+wood door frame is as high as that of the original LVL product.

Summary

 the WPC+wood co-extrusion door frame can be made with both advantages of wood and WPC, it is water proof, fire proof, insect proof, high strength, high toughness,high nail/screw holding strength,smooth and beautiful outlook which can be embossed/laminated/painted
