Single-End Heating Tube

The Single-End Heating Tube is an industrial-grade electric heating element designed for applications where space constraints or mechanical design prevent wiring access at the tip of the heater. As the name suggests, both the electrical connection and the support flange (if applicable) are located at the same end. This unique configuration makes it the ideal choice for heating closed-end holes in metal blocks, injection molds, and rolling cylinders where a clean, streamlined installation is required.

Single-End Heating Tube (Single-Ended Immersion Heater)
The Single-End Heating Tube is an industrial-grade electric heating element designed for applications where space constraints or mechanical design prevent wiring access at the tip of the heater. As the name suggests, both the electrical connection and the support flange (if applicable) are located at the same end. This unique configuration makes it the ideal choice for heating closed-end holes in metal blocks, injection molds, and rolling cylinders where a clean, streamlined installation is required.

Key Advantages of Our Single-End Design

Exclusive One-Side Wiring: Unlike standard tubular heaters that require termination at both ends, our single-end design concentrates all electrical connections at the rear. This simplifies control panel wiring and saves valuable space in compact machinery.
Perfect for Blind Holes: Specifically engineered for "blind hole" installation (holes with a closed bottom). The heating element reaches almost the full length of the tube, maximizing the heat transfer surface area within the block without protruding out the back.
High Thermal Efficiency: Featuring a tight tolerance design (typically -0.05mm to -0.10mm), the tube fits snugly into the drilled hole. This minimizes air gaps and ensures rapid, efficient heat transfer from the element to the target material.
Vibration Resistant: Built with a fully compacted magnesium oxide core, the internal resistance wire is held firmly in place. This prevents "slumping" or short-circuiting, even in high-vibration environments like industrial molding machines.

Core Industrial Applications

From plastic injection molding, die-casting, and extrusion dies to laboratory instruments and packaging equipment, the Single-End Heating Tube is indispensable for precise temperature control. We offer standard models in various diameters and voltages, as well as OEM customization services for special sheath materials (SUS304, Incoloy, etc.) and embedded thermocouples. Choose our heating tubes for reliability, longevity, and superior performance.
