China UPVC profile machine Manufacturer, Supplier, Factory, CE certified

the confluence core plays a very important role in the wood-plastic extrusion system.Based on many years of production experience, Yongte has continuously optimized every detail of the wood-plastic equipment. Our confluence core is designed according to the special properties and processing requirements of wood-plastic composite materials, which can form a suitable extrusion pressure in the process from the wood-plastic extruder to the wood-plastic mold. This can not only help the wood-plastic composite materials to better blend and plasticize, thereby improving the quality and strength of the final product; it can also effectively increase production speed and output.

Yongte is professional manufacturer of WPC machines with high quality and great service.Today, the manufacturing of a high-quality and high-efficiency conical double screw wood plastic WPC extruder was successfully completed.

Yongte’s solid core WPC door jamb machine has achieved a milestone with successful on-site testing for a leading Indian building materials manufacturer, marking its seamless adaptation to the Indian market’s unique demands. This breakthrough underscores the machine’s reliability and Yongte’s expertise in delivering customized plastic extrusion solutions for global clients.

1. Unstable extrusion volume: It may be due to uneven feeding, such as fluctuations in feeding speed, blockage of feed port, uneven size of raw material particles, etc.; it may also be caused by wear of the extruder screw, unstable screw speed, or uneven barrel heating temperature. 2. Plastic scorching: If the barrel temperature is too high, the screw speed is too fast, the gap between the screw and the barrel is too small, or the material stays in the barrel for too long, it may cause plastic scorching, causing the product to change color, decompose and other problems.

Waste plastics are transforming from an environmental burden into an "urban mineral," and wood-plastic profile production lines have become a new investment area attracting significant attention. A recent report from the United Nations Environment Programme indicates that the world generates 340 million tons of plastic waste annually, with used plastic packaging accounting for over 30% of this waste, yet only 10% is effectively recycled. These improperly handled plastics, whether landfilled, discharged into the ocean, or incinerated, cause persistent damage to soil, ecosystems, and air quality. Against this backdrop, the wood-plastic profile industry, which transforms waste plastic into high-value-added products, presents a significant development opportunity.
