China HDPE large pipe machine Manufacturer, Supplier, Factory, CE certified

Yongte Company's newly launched SJSZ35/75 conical twin screw co-exrusion machine achieves green production through technological innovation, offering both cost reduction and efficiency gains. Having secured international orders, the company plans to leverage this breakthrough to further expand its overseas market presence.

The screw of WPC extruder serves as the core transmission and plasticizing component of the equipment. It directly contacts the molten material of the wood-plastic composite and withstands high temperatures and high pressures. Its corrosion resistance is crucial to ensuring stable operation, product quality, and longevity. Therefore, Yongte's wood-plastic composite extruders typically use screws and barrels made of wear-resistant and corrosion-resistant materials.

When selecting additives, the synergy and mutual influence between additives should also be considered, and the best addition amount and combination should be determined through experiments to ensure that wood-plastic products meet the expected performance and quality requirements.

As the core equipment of a wood-plastic composite (WPC) production line, the screw operation of the wood-plastic extruder directly affects production stability.

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.

the high-performance plastic film recycling compacting granulator independently developed and manufactured by Yongte Plastic Tech has successfully passed strict factory trial operation and official inspection. The complete equipment has been fully packaged and officially shipped to Africa, marking another solid breakthrough for Yongte Plastic Tech in the African environmental protection recycling equipment market.
