Project Background

Customer Requirement

The customer needed a reliable and efficient extrusion line capable of producing high-quality PA6 and PA12 nylon tubes. The system had to provide stable production, accurate tube dimensions, advanced automation and easy integration into the customer’s existing manufacturing process.

Key requirements included:

• Production of PA6 and PA12 nylon tubes
• Stable and efficient extrusion performance
• High dimensional accuracy for precision tube applications
• Advanced automation and control
• Reduced downtime during production
• Smooth integration with existing factory operations
• Reliable hauling, cutting and finished product collection

QTech-Machinery Solution

QTech-Machinery supplied a complete precision tube extrusion line with an SJ65 single screw extruder, vacuum cooling and sizing water tank, immersion stainless steel cooling tank, precision servo belt hauling and rotary cutting machine, and finished product conveyor with collection trough.

The line was designed to support precise extrusion, stable cooling, accurate sizing and clean cutting, helping the customer improve production efficiency and product consistency.

Key Machine Configuration

What Visitors Can See in the Video

Complete Precision Tube Production Flow

The video shows the full production process of a precision tube extrusion line, from raw material extrusion to sizing, cooling, hauling, cutting, conveying and final collection. It gives viewers a practical understanding of how each section works together to produce consistent tube quality.

Stable Single-Screw Extrusion

The SJ65/28 single screw extruder is the core machine of the line. Equipped with a 37 kW Inovance servo motor, ceramic heaters and Siemens PLC control, it supports stable plasticizing and precise extrusion control for PA6 and PA12 nylon materials.

Vacuum Cooling and Accurate Sizing

The vacuum cooling and sizing water tank helps maintain tube roundness, outer diameter accuracy and surface quality. The electronic vacuum gauge with manual and automatic adjustment allows operators to fine-tune the sizing process for different tube specifications.

Immersion Cooling for Product Stability

After initial sizing, the tube passes through a 6-meter stainless steel immersion cooling tank. This provides additional cooling time and helps stabilize the tube shape before hauling and cutting.

Servo Hauling and Rotary Cutting

The precision servo belt hauling and rotary cutting machine provides stable traction and accurate tube length control. With a hauling speed of 0-40 m/min and cutting precision of ±0.5 mm, it is suitable for applications requiring high dimensional accuracy.

Finished Product Conveying and Collection

The finished product conveyor belt and collection trough help transfer cut tubes smoothly after production. The adjustable conveyor speed allows the system to match different production speeds and product sizes.
