Counter-Rotating Conical Twin-Screw Sino-Tech Plastic Extruder Equipment for UPVC PVC Pipe Double Pipe Plastic Making

Product Description

The PVC Pipe production line is mainly used in the area of agricultural water supply system, architectural water supply system(water supply and drainage pipe), pavement of cables and as well as different diameter and thickness of PVC Pipes. The complete PVC Pipe production line is composed by conical twin screw extruder, pipe extrusion mold, vacuum calibration tank, haul off machine, cutter and stacker, belling machine (flaring machine). The main extruder and haul off we adopts ABB inverter, vacuum pump and motors adopt high quality famous brand. Haul off machine has two claws, three claws, four claws, six claws and eight claws accord to different pipe diameters. For pipe cutting machine has saw and planetary cutting type, which additionally attached with the meter counter and intensifying device. The production line is easily installation and operation, simple maintenance with reliable quality.

Production Process

Material → mixer → forced Feeding → conical double screw extruder → mould&calibrator → vacuum spay cooling tank → printer→ haul-off → cutter → stacker

The whole production line

Features

• Model SJSZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.
• The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.
• The conical twin screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.
• The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.
• The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.
• The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.

Services

1. We could send engineers to the buyer's factory for installation instruction, commissioning and training service at buyer's cost.

2. Our machine has one year guarantee since the installation in buyer's factory. During the guarantee time, if any parts (except the easy damaging parts) are damaged under normal operation, we will offer free spare parts. After the guarantee time, we will offer the spare parts with cost price.

3. If the buyer has any problem during the operation, we will offer technical solutions.

We have been making research and development for special material of PA66GF25 thermal break strip since 2006, we have a deep understanding and rich experience of the relevant industry. We can provide our clients with special material of PA66GF25 thermal break strips of all levels. During these years, we also established a good partnership with many companies is the upstream and downstream industry.

In 2016, we together with factory of mold, extruder and factory of thermal break strips established Zhangjiagang Bangyu Engineering Plastics Co.,Ltd, which is responsible for international import and export business. In 2021, Zhangjiagang Bangyu Engineering Plastics Co.,Ltd was changed ans registered as Suzhou Polywell Engineering Plastics Co.,Ltd. 
The reason why we joined Polywell together with the other two companies is that in this field, the requirements for professionalism are very high. In this field, the company that produce raw materials usually do not research machines and molds, but clients usually need all of them. We found this point, so we joined two other companies established Polywell company together. Polywell can provide a whole set of solution about thermal break strips, including raw material –PA66GF25 granules, extruders, molds, and technical support. This is our biggest advantage.

Strive for customers’ satisfaction and success, service to customers is the principle we’ve always been insisting in the last ten years, to provide our customers with high-quality products and service.

Our domestic sales volume is very stable. We are the main supplier of two listed companies which produce aluminum profile at home, and will obtain the long-term cooperation with them. Otherwise, we also have the long-term cooperation with many small manufactures.

If customers have the need of purchasing other products, we can also provide procurement service.
