China WPC board machine Manufacturer, Supplier, Factory, CE certified

Yongte Wood-Plastic WPC Door Frame Extrusion Line is specialized equipment designed for manufacturing PVC-based wood-plastic composite door frames. By combining PVC plastic with fine wood powder and employing microfoaming molding technology, the final product features robust structural integrity, exceptional durability, lightweight construction, and ease of transportation and installation. However, in actual production operations, inaccurate or improper temperature parameter settings by operators often result in quality defects in the output profiles, failing to meet compliance standards. To address this issue, Yongte's technical team has compiled detailed temperature calibration guidelines based on extensive practical experience, providing actionable reference for manufacturing processes.

On May 19, 2025, the wood plastic pelletizing production line independently developed by Qingdao Yongte Plastic Machinery successfully completed trial operation at the Qingdao production base. With its excellent performance of stability, high speed, safety and durability, it has set a new technical benchmark for the wood plastic production industry. In the context of the industry where the market size of my country's wood plastic composite materials will reach 58 billion yuan in 2024 and the annual growth rate is 16.3%, Yongte Plastic Machinery has spent 3 years and invested 28 million yuan in research and development funds to successfully overcome many technical difficulties and create this intelligent production line.

Yongte Plastic Machinery Co., Ltd. has been committed to developing environmentally friendly and innovative plastic machinery technology to achieve sustainable utilization of resources. Today, we are proud to announce that we have successfully developed a new technology and equipment that can produce wood-plastic products from waste circuit board materials.

the conical twin-screw extruder is based on the melting and extrusion of plastic under the rotation and pushing action of the screw. When the raw materials are fed into the hopper of the conical twin-screw extruder, they are sheared, mixed and melted by the screw to form a uniform melt. As the screw rotates and pushes, the melt is transported to the die of the machine head and finally extruded.

Through the maintenance, the service life of wood-plastic WPC profile molds can be effectively extended, production efficiency and product quality can be improved, and production costs can be reduced. It should be noted that specific maintenance measures should be appropriately adjusted and optimized according to the actual use of the mold, the production environment and the manufacturer's suggestions. At the same time, establishing a complete maintenance record archive will help track the maintenance history and status of the mold and provide a reference for subsequent maintenance work.
