China MPP power pipe extrusion line Manufacturer, Supplier, Factory

In recent years, the accelerated construction of infrastructure such as municipal drainage and water conservancy projects has driven a surge in market demand for large-diameter PVC pipes over 600mm. However, on the production side, many companies have long been plagued by several stubborn issues: uneven plasticization of raw materials, resulting in pipes that are "brittle in one section and soft in another"; inaccurate wall thickness control affecting the project's compressive strength; and frequent equipment maintenance slowing production progress. These pain points not only drive up production costs but also pose risks to project quality. To address these common industry challenges, Yongte Plastic Machinery recently completed a comprehensive upgrade of its large-diameter PVC pipe production line. Through innovative optimization of core components, it has delivered a practical solution.

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.

Amidst the global acceleration of plastic pollution control and the development of a circular economy, the disposal of used plastic crates is becoming a headache for many businesses and regions. These crates are widely used in industries like manufacturing and logistics, and their durability and lightweight nature mean they are in high demand. However, once worn and damaged, systematic solutions are often lacking. If carelessly piled or landfilled, they can remain difficult to degrade for decades, gradually releasing microplastics and harmful substances, causing long-term pollution to soil and water sources. Currently, many recycling channels are inefficient, difficult to sort, and contain high levels of impurities, resulting in a large number of used crates going unused, wasting resources and increasing the environmental burden.

Waste disposal has always been a thorny issue in the plastics manufacturing industry. Defective products and scraps generated during the production process not only waste raw materials but also pose the risk of illegal disposal. Traditional recycling methods often suffer from process deficiencies, resulting in inconsistent quality of recycled materials and making them difficult to reuse directly. To address this pain point, Yongte Plastic Machinery has launched a customized granulation line. Through multi-material adaptability, high-precision process control, and environmentally friendly design throughout the entire process, it transforms waste into qualified recycled raw materials, helping companies achieve both economic and environmental benefits.
