HOT RUNNER COIL · APPLICATION PATHS

Replacing a nozzle coil or qualifying another supplier?

Start with your current nozzle geometry or new tool layout. We will review fit, electrical targets, leads and sensing before confirming a build.

01 · REPLACEMENT

Replace a failed or worn part

Send the nozzle or coil inner diameter, heated length, winding pitch, voltage, wattage, lead exit and thermocouple details, if present.

Start a replacement brief

02 · SECOND SOURCE

Qualify an interchangeable part

Share the approved coil drawing or current reference, nozzle fit, lead and sensor arrangement and expected annual quantity. State any qualification tests you require.

Start a second-source brief

03 · NEW PROJECT

Specify a new design

Describe the nozzle diameter, heated zone, mounting constraints, voltage, power and temperature sensing for the new tool.

Construction

Purpose-built from
the inside out.

The heating conductor is insulated and protected within a compact metal profile, then wound to match the target nozzle geometry. Tight contact and controlled pitch give the assembly a fast, predictable thermal response.

CONCEPT VIEW

The drawing communicates functional layers. Final construction follows the approved product drawing.

Applications

Where this product
does its best work.

The final configuration is matched to the mounting conditions, thermal load and control system in the finished equipment.

Hot Runner Nozzles

Close-fit heating around injection nozzles.

Manifold Systems

Controlled heat at gates and distribution points.

Compact Tooling

Cylindrical parts with restricted installation space.

Engineering reference

A flexible starting
specification.

Values shown are typical design ranges. Production specifications are confirmed against the approved drawing and application conditions.

Profile Options

Round, square and rectangular cable profiles.

Sensor Integration

J or K type thermocouple options.

Winding Geometry

Pitch and inner diameter built to the supplied drawing.

Lead Protection

Braided, armored and formed exit configurations.

Inner Diameter	Drawing dependent
Rated Voltage	24–240 V custom
Conductor	Nichrome 80/20
Insulation	Compacted MgO / ceramic
Temperature Range	Up to 750°C
Configuration	Wound-to-fit

APPLICATION NOTE

The heater must maintain close, even contact with the nozzle. Air gaps can create local hot spots and shorten operating life.

Custom configuration

Make it fit the
application exactly.
