China PP packing strap extrusion line Manufacturer, Supplier, Factory

PVC pipe production line is a complete set of equipment that processes PVC raw materials into pipes through continuous extrusion molding. The core is to realize the automated process of raw material melting, molding, shaping and cutting. Its stability directly determines the dimensional accuracy and physical properties of the pipes.

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 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.

Recently, some customers in the use of wood plastic granulator production process blockage, seeking our help!

WPC foam board, also known as wood-plastic composite foam board, is a new type of environmentally friendly building material. It uses wood powder, plastic, etc. as the main raw materials, and is made by adding an appropriate amount of foaming agent and other additives through mixing, extrusion, foaming, molding and other processes. Wood-plastic foam board has the dual advantages of wood and plastic.
