QTech-Machinery Nylon Tube Extrusion Line

QTech-Machinery Nylon Tube Extrusion Line

Introduction

This video presents a complete nylon tube extrusion line supplied by QTech-Machinery for PA tube manufacturing. The footage shows the actual production process after installation and commissioning, including extrusion, tube forming, vacuum calibration, water cooling, servo haul-off, automatic cutting, conveying, and finished tube collection.

The line is designed for producing nylon / PA tubes used in industrial tubing, pneumatic systems, automotive-related pipe applications, cable protection, and general plastic tube production. It is suitable for customers searching for nylon tube extrusion line, PA tube production line, plastic tube extrusion machine, nylon pipe extruder, PA6 PA12 tube extrusion machine, and automatic plastic tube cutting line.

Instead of showing only one machine, this video demonstrates how a complete extrusion system works as an integrated production line. Viewers can clearly see how the nylon material is processed from raw plasticizing to finished tube output.

Project Background

Customer Need

The customer required a complete extrusion production line for continuous nylon tube manufacturing. Their key concerns included stable tube forming, accurate sizing, reliable cooling, synchronized traction, automatic fixed-length cutting, and organized finished product collection.

Because nylon tubes are often used in applications where dimensional consistency and surface quality are important, the customer needed more than a basic extruder. QTech-Machinery provided a full line solution with upstream extrusion, downstream calibration, cooling, hauling, cutting, conveying, and collection.

Why This Line Was Selected

Nylon / PA material requires stable plasticizing temperature, proper die design, accurate vacuum sizing, and sufficient cooling. If any part of the line is not well coordinated, the tube may show diameter fluctuation, unstable wall thickness, deformation, or poor cutting quality.

For this reason, QTech-Machinery designed the line as a complete system. The extruder, die, vacuum tank, cooling tank, servo haul-off, cutter, conveyor, and PLC control system work together to support continuous production.

What the Video Shows

Complete Production Workflow

The video shows the nylon tube passing through the full production process:

Main Viewing Points

When watching the video, viewers can focus on:

• Continuous tube movement from extrusion to collection
• Stainless steel vacuum and cooling tanks
• Servo-driven haul-off and cutting system
• Automatic conveyor transfer after cutting
• Finished tube collection in the stainless steel trough
• PLC and HMI control interface for line operation

Equipment Displayed in the Video

1. SJ65/28 Single Screw Extruder

The SJ65/28 single screw extruder is the main plasticizing machine of the line. It melts nylon material and supplies stable melt flow to the extrusion die.

What Viewers Can See

The extruder operates as the starting point of the production line. It provides continuous plasticizing and stable material feeding for nylon tube production.

2. Customized Tube Extrusion Die

The extrusion die shapes the molten nylon into a continuous tube. It is customized according to the required tube diameter and wall thickness.

What Viewers Can See

The video shows the tube forming area where the material changes from molten plastic into a continuous tube profile.

3. Vacuum Calibration Tank

The vacuum calibration tank controls tube diameter and roundness during the early cooling stage. It is important for maintaining stable tube dimensions.

What Viewers Can See

The tube enters the stainless steel vacuum tank for sizing and initial cooling. The tank structure supports observation and alignment adjustment.

4. Immersion Cooling Tank

After vacuum calibration, the nylon tube passes through the immersion cooling tank for additional water cooling and shape stabilization.

What Viewers Can See

The video shows the tube moving through the water cooling tank before reaching the traction and cutting section.

5. Servo Belt Haul-Off Machine

The servo belt haul-off pulls the tube forward at a controlled speed. It helps maintain production continuity and supports stable tube dimensions.

What Viewers Can See

The haul-off section shows the tube being pulled steadily. Stable traction is important for tube wall thickness and line speed control.

6. Rotary Flying Knife Cutter

The rotary flying knife cutter cuts the moving tube without stopping production. It is suitable for automatic fixed-length cutting.

What Viewers Can See

The cutter works online after the haul-off machine. The tube is cut into preset lengths while the extrusion process continues.

7. Conveyor and Collection System

After cutting, the tubes are transferred by conveyor and collected in a stainless steel trough.

What Viewers Can See

The finished tubes are moved away from the cutter and collected automatically, making the downstream process cleaner and more efficient.

8. Electrical Control System

The electrical system integrates the full line and allows operators to manage production parameters through the HMI touch screen.

What Viewers Can See

The control cabinet and HMI interface show how operators monitor and adjust the production line during operation.

Commissioning Result Shown in the Video

Evidence-Based Result

After installation and commissioning, the line shown in the video was able to operate through the complete production process. The footage supports that the nylon tube passed continuously through extrusion, forming, vacuum sizing, water cooling, servo traction, automatic cutting, conveying, and collection.

Note

The video demonstrates machine operation and production workflow. Specific product inspection data, such as dimensional tolerance, pressure testing, tensile testing, or material certification, should be confirmed separately according to the customer’s acceptance documents.

Application Fields

Typical Uses of Nylon Tubes

The nylon tubes produced by this type of extrusion line can be used in many industries, depending on material grade, tube size, and customer standards.

Main Advantages Shown in the Video

Integrated Production Line

The video shows a complete production system, not just a single extruder. This helps customers understand the full process from material melting to finished tube collection.

Stable Extrusion and Forming

The SJ65/28 extruder and customized die provide the basis for continuous nylon tube forming.

Accurate Vacuum Sizing

The vacuum calibration tank helps control tube diameter and roundness during the early cooling stage.

Sufficient Cooling Distance

The combination of vacuum cooling and immersion cooling supports tube stabilization before traction and cutting.

Servo Downstream Control

The servo haul-off and servo cutter help maintain stable pulling and automatic fixed-length cutting.

Reduced Manual Handling

The conveyor and automatic collection system transfer and collect finished tubes after cutting, reducing manual pickup work.

Centralized Operation

The Siemens PLC and HMI system allow operators to set and monitor the line more conveniently.
