Ultra-Compact Minitubular Coil Heater ID9.5mm Section 3.2x1.8mm For Limited Spaces

Custom Hot Runner Heating Elements for Industrial Injection Molding.

1. Introduction

Our High-Difficulty 9.5mm Micro ID Coil Heater (9.5x48mm) represents the pinnacle of precision thermal engineering. Winding a heavy-duty heating element into an ultra-small internal diameter of just 9.5mm requires exceptional manufacturing mastery to prevent internal wire damage or outer sheath wrinkling. Featuring a tight 3.2x1.8mm flat cross-section, this micro heater is specifically built for elite industrial applications where standard compact heaters fail to meet the extreme dimensional tolerances.

2. Features

• High-Difficulty Micro ID (9.5mm): Manufacturing a functional coil heater with a tiny 9.5mm inner diameter demands advanced CNC winding technology. We successfully overcome the extreme stress limitations of the material where ordinary factories cannot.

• Flawless Micro-Winding Craftsmanship: Our specialized forming process guarantees a perfectly uniform internal bore and seamless pitch distribution, ensuring a flawless, snug fit on micro-nozzles without any hot spots.

• Low-Profile Flat Section (3.2x1.8mm): The precise rectangular profile maximizes contact surface area in ultra-confined spaces, boosting heat transfer efficiency far beyond traditional round-wire alternatives.

• Premium Thermal Reliability: Despite the extreme structural stress required during its high-difficulty bending process, our heaters undergo strict rigorous testing to ensure long-term dielectric strength and durability.
