Heatecx Limited
The HTD-3 microtubular heater coiling machine is a high-precision equipment specifically designed for forming hot runner heaters. This machine efficiently transforms flat or tubular heating elements into compact helical coils, essential for heating injection nozzles. Thanks to its stepper motor-driven mandrel shaft, it ensures absolute control over the internal diameter and coil pitch, allowing the processing of small-diameter round tubes and square sections with unparalleled repeatability in industrial production environments.
Optimize your nozzle heater production with our PLC-controlled automatic coiling machine. This helical heater manufacturing machine stands out for its versatility, allowing the use of interchangeable mandrels from 15mm to 60mm. Equipped with an intelligent pneumatic clamping system and an automatic demolding mechanism, the machine reduces downtime and maximizes efficiency. It is the ideal solution for hot runner system manufacturers who need to bend square section materials (2x2mm to 5x5mm) or circular profiles, ensuring a perfect fit on the injection nozzle.
This equipment excels in the market by combining mechanical robustness with electronic precision:
• Precise Movement Control: The stepper motor driving the central shaft enables decimal control over rotation, resulting in an exact and consistent thread pitch.
• Versatile Section Processing: Unique capability to process both circular and flat or square section heating elements, maintaining form integrity without unwanted deformations.
• Integrated Automation: Controlled by a PLC system, the machine manages everything from initial blowing/clamping to automatic discharge of the finished part, allowing a single operator to manage multiple units.
• Quick Changeover System: Mandrels are easily interchangeable, enabling the production of mini-spirals from 15mm to industrial coils of 60mm in just a few minutes.
• Secure Pneumatic Clamping: The pneumatic clamping block ensures the start of the heater with just the right pressure, preventing marks on the metal while guaranteeing no slippage during axial coiling.

The robust design of the machine is engineered for mechanical durability:
1 Traction Module: Composed of a high-torque stepper motor that ensures constant coiling speed even for larger section heating elements.
2 Interchangeable Mandrel Head: Central shaft where the heater is coiled. Includes the pneumatic clamping block that acts as the initial anchor point.
3 Axial Pressure Mechanism: Pneumatic system that presses the tube against the mandrel as it advances longitudinally to form the helix.
4 Ejection Unit: Automatic demolding system that removes the finished heater from the mandrel, streamlining the workflow.
5 Control Cabinet: Houses the PLC and motor drivers, with electrical protections according to international standards.
In the design of hot runner nozzle heaters, thermal uniformity is critical. Our machine allows programming a variable pitch. This means you can concentrate more turns of the heater at the ends of the coil and space them further apart in the center. Why is this vital? Nozzle tips often lose heat faster due to contact with the cold mold. By increasing the density of turns in these areas (thermal compensation), the machine ensures that the nozzle tip maintains the exact polymer temperature, preventing material freezing or injection defects.
