With the continuous advancement of municipal engineering and water conservancy construction, the demand for large-diameter PVC pipes continues to rise. These pipes are not only corrosion-resistant but also have relatively controllable overall costs, making them the preferred choice for many projects. However, on the production side, many companies are often troubled by several long-standing problems—especially with large-diameter PVC pipes exceeding 500 mm in diameter. During production, issues such as unstable molding, uneven wall thickness, and high energy consumption are common, directly impacting product qualification rates and production costs.

The deformation challenge of wood-plastic composite WPC wall panels represents a "systemic process" that requires adherence to a comprehensive workflow: moisture control in raw materials → uniform plasticization → gradual cooling → stress release → standardized storage. The key lies in balancing the distinct characteristics of wood fibers and plastics to minimize internal stress accumulation. By precisely regulating critical parameters (particularly moisture content, temperature, and cooling rates) alongside optimized equipment and quality monitoring, deformation can be controlled within 1%, meeting both production requirements and application needs.

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.
