There are some difficulties and solutions in the production and manufacture of wood-plastic composite hollow veneer fence profiles:
1. Material compatibility: The compatibility of wood fiber and plastic in wood plastic materials is not easy to control, which may cause the combination to be not tight and affect product performance.
The solution:
Optimize the formulation, select the right type of plastic and wood fiber, and add compatibilizers to improve the combination of the two.
Pretreatment of raw materials, such as drying and surface modification of wood fibers.
2 .extrusion process control: To ensure the uniformity and stability of the hollow structure, the extrusion temperature, pressure and speed control requirements are high.
The solution:
Advanced temperature and pressure control systems ensure stable parameters during extrusion.
Install on-line monitoring equipment to adjust temperature, pressure and speed in real time.
3. Mold design: Suitable mold design is crucial to achieve the complex shape and hollow structure of profiles, and the accuracy of the mold and the flow channel design directly affect the product quality.
The solution:
Optimize mold structure and flow path design with computer simulation technology.
Adopt high-precision machining equipment to manufacture molds to ensure the accuracy of molds.
4. Surface finishing treatment: To achieve a good finishing effect and maintain durability, there are challenges in the process, such as the adhesion and wear resistance of the finishing material.
The solution:
Select high performance finishing materials and use suitable binders to improve adhesion.
Add pretreatment processes such as surface cleaning and activation to enhance the durability of finishes.
5. Dimensional accuracy control: Due to material characteristics and shrinkage in the production process and other factors, it is difficult to accurately control the dimensional accuracy of profiles.
The solution:
Establish a strict quality control system, and carry out dimensional inspection and adjustment for each batch of products.
Optimize the cooling system to control the shrinkage rate of the material.
6 .Product strength and toughness balance: to ensure that the fence profile has enough strength, but also to have a certain toughness to resist impact and deformation.
The solution:
Adjust the ratio of reinforcement materials in the material formulation, such as adding glass fibers.
Optimize the extrusion process parameters and improve the microstructure of the material.
7. Production efficiency and cost: under the premise of ensuring quality, improving production efficiency and reducing production costs is also a difficult point.
The solution:
Automate the production line to reduce manual intervention and improve production efficiency.
Reasonable arrangement of production plan, reduce inventory costs.
