Product Description, cartridge heater , cartridge heating element

EPT supplies OEM customised  cartridge heaters are precision-engineered cylindrical heating elements designed for direct insertion into drilled holes in metal tooling, moulds, dies, platens, and process equipment. The stainless steel sheath combined with compacted magnesium oxide (MgO) insulation and a resistance wire coil delivers reliable, efficient, and uniform heat transfer in demanding industrial environments. And we supply PTC cartridge heater as well Available in both standard and fully custom configurations, these heaters are manufactured to drawing to match exact customer specifications.

Key Features

-        Stainless steel sheath - Provides excellent corrosion resistance, mechanical strength, and durability in harsh industrial environments.

-        Uniform heat distribution - Tightly wound resistance coil with compacted MgO insulation ensures even heat transfer and fast thermal response.

-        Flexible wattage density - Available in both low and high watt density designs to suit a wide range of heating applications and material sensitivities.

-        Low wattage density option - Gentle, gradual heating (typically below 25 W/in2) reduces the risk of hot spots and element burnout, ideal for heat-sensitive applications and extended service life.

-        High temperature capability - Operates effectively up to 750 degrees C (1400 degrees F) depending on design and sheath material selection.

-        Custom sizing - Manufactured to customer drawings in a range of diameters and lengths; OEM and ODM services available.

-        Multiple termination options - Available with flying leads, screw terminals, or ceramic terminal blocks for flexible installation.

-        Moisture-resistant sealed construction - Epoxy or ceramic end seal protects against moisture ingress and extends operational life.

-        Precise fit - Close-tolerance sheath dimensions ensure optimal contact with the bore for maximum heat transfer efficiency.
