16-50mm Four Cavities PVC Pipe Production Line

Four Cavities PVC Pipe Production Line Introduction

The four cavities PVC pipe production line is a kind of equipment used to produce polyvinyl chloride (PVC) pipes. It has the characteristics of high efficiency, stability and high degree of automation. The four design enables the four cavities PVC pipe extrusion line to extrude four PVC pipes at the same time, which greatly improves the production efficiency compared with the traditional single-tube extrusion line. In the same time, more pipes can be produced to meet the needs of large-scale production, help customers increase production and increase economic benefits.

The four cavities PVC pipe production line is mainly composed of PVC pipe extruder, mold, cooling device, tractor, cutter and stacking device, etc., and each part works together to achieve efficient production of PVC pipes.

Features of Four Cavities PVC Pipe Extruder:

The use of advanced extrusion technology and precision mold manufacturing can ensure high dimensional accuracy, uniform wall thickness, smooth surface, and stable and reliable product quality of the pipe.
The four cavities PVC pipe making line is equipped with an automated control system, which can realize precise control of equipment such as extruders, tractors, cutters, etc., reduce the error of manual operation, and improve the stability and consistency of production. At the same time, it also has fault alarm and automatic shutdown functions, which is convenient for equipment maintenance and management.
According to different production needs, PVC pipes of different specifications and uses can be produced by changing molds and adjusting process parameters, such as water supply pipes, drainage pipes, threading pipes, etc.

Components of Four Cavities PVC Pipe Line:

Extruder

The extruder is used to plasticize and melt the dry blend mixture, provide a stable, consistent, and high-volume output of molten PVC to adequately supply all four cavities without pulsation.

Four-Cavity Die Head

Each path forms an individual pipe, ensure absolutely uniform flow to each cavity, guaranteeing that all four pipes have the same wall thickness, diameter, and mechanical properties.

Vacuum Calibration Tank

The newly formed pipes enter this tank. Vacuum sizing plates inside the tank cool the pipes and precisely calibrate their outer diameter (OD) to the exact specification.

Haul-Off

A haul-off unit with four independent tracks, grips all four pipes simultaneously and pulls them at a constant, controlled speed from the die, ensuring smooth and stable operation.

Cutter

An automatic traveling cut-off saw that can cut all four pipes to the required length (e.g., 4m or 6m) at the same time. It moves with the pipes during the cut and returns to its start position.

Stacker

After cutting, a robotic arm or automatic stacker collects the pipes and stacks them neatly onto a pallet or rack, ready for packaging and shipment.

PVC Pipe Application Range:

The pipes produced by the PVC pipe extrusion line can replace metal pipes in the field of building water supply and drainage due to their advantages such as corrosion resistance. In terms of wire and cable protection, they are used for building electrical installations with good insulation and mechanical strength. In agricultural irrigation, they can be used for water pipelines with good corrosion resistance. In addition, they are also widely used in many fields such as chemical industry, communication, municipal engineering, etc., such as chemical pipelines, communication cable sheath pipes, urban drainage pipelines, etc.
