High Density Cartridge Heaters

High-density cartridge heaters are compact, cylindrical electric heating elements designed to deliver high watt density (heat output per unit area) in confined spaces. They are widely used for localized, high-temperature heating in industrial applications.

​

Key Feature:

• Construction: Stainless steel sheath, tightly packed magnesium oxide (MgO) insulation, and a nichrome heating coil.
• Watt Density: Typically 60 to 200 W/in² or higher.
• Temperature Capability: Can operate at temperatures up to 750°C (1380°F) or more.
• Precision Fit: Designed to be inserted into drilled holes with a snug fit for optimal heat transfer.

​

Advantages:

• High efficiency due to excellent heat transfer
• Long lifespan from durable construction and uniform heating
• Compact size, allowing use in tight spaces
• Customizable in terms of length, diameter, wattage, and termination style

​

Application:

• Plastic injection molding (e.g., hot runner systems)
• Packaging and sealing equipment
• Dies and molds
• Medical and laboratory equipment
• Food processing machinery
