As the world accelerates towards carbon neutrality, the photovoltaic industry has flourished at an astonishing speed. According to data from the International Renewable Energy Agency (IRENA), global photovoltaic installed capacity is doubling every four years. However, hidden worries have emerged behind the glory - it is estimated that by 2050, the world will accumulate 78 million tons of retired photovoltaic modules. These "photovoltaic waste" that once made great contributions to clean energy are now being transformed into "green treasures" in the field of wood-plastic products through technological innovation, detonating a circular economy market of hundreds of billions of yuan.

The screw extruder relies on the pressure and shear force generated by the rotation of the screw, which allows the material to be fully plasticized and evenly mixed, and then formed through the die. [2] Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screw-less extruders.

The parallel twin-screw extruder consists of two screws arranged in parallel, forming a long and narrow material channel between them. When the material is fed into the extruder, the two screws rotate and mesh with each other to push the material forward and gradually compress it. In this process, the material is subjected to various effects such as shearing, mixing and heating, thereby achieving plasticization and melting.

In the field of plastic extrusion equipment, the screw is the core "heart" component, and its performance directly determines the production efficiency, product quality and enterprise economic benefits. Authoritative data shows that improper screw design and material selection may lead to a 30%-50% decrease in production efficiency, a product defect rate soaring to more than 20%, and even equipment failures causing high downtime losses. Yongte Plastic Machine has been deeply involved in the industry for many years and has always regarded screw technology research and development as its core competitiveness. With high-quality material selection and scientific design, it provides customers with highly adapted extrusion solutions. ​
