As a coil heater supplier, EaseWise supports OEM heating requirements worldwide.
Learn how a coil heater works, including its heating principle, construction, temperature control, and common industrial applications.
Wide Application
Injection Molding
Coil heaters are widely used on injection molding machine nozzles and barrels, providing uniform external heating for consistent melt temperature and shot-to-shot repeatability.
Hot Runner Systems
Precision heating for hot runner manifolds and nozzles, ensuring stable melt flow and minimizing cold slug formation in multi-cavity molds.
Extrusion
Applied on extruder barrels and die heads, coil heaters deliver even heat distribution for consistent material processing across thermoplastics and engineering resins.
Packaging & Sealing
Used in heat-sealing bars, shrink tunnels, and packaging machinery where compact, high-temperature heating elements are required.

Frequently Asked Questions
Stainless steel coil heaters excel in high-temperature environments (up to 850°C) and offer superior corrosion resistance, making them ideal for demanding industrial applications. Brass coil heaters provide significantly better thermal conductivity — meaning faster heat-up and more uniform heat transfer — and are well-suited for general-purpose injection molding below 400°C. The choice comes down to your operating temperature and environment rather than a simple cost comparison.
