Product Overview
Custom cartridge heaters for molds and heating blocks
Cartridge heaters are compact cylindrical heating elements designed for concentrated heat transfer. They are commonly inserted into metal blocks, molds, dies and machine parts.
What is a cartridge heater?
Compact high-density heating element
A cartridge heater is a cylindrical electric heating element that is usually inserted into a drilled hole to heat a metal block, mold, die or machine component. It is widely used where stable and concentrated heat is required in a limited space.
Jouheat supports custom cartridge heaters by diameter, length, voltage, wattage, sheath material, lead wire direction, right-angle structure, flange option, thermocouple integration and working temperature.
Made-to-Order Supply
Custom cartridge heaters for molds, tooling and machine replacements
Jouheat manufactures cartridge heaters from confirmed hole size, electrical ratings, lead structure and working conditions. These heaters are intended for OEM equipment, molds, heating blocks and replacement projects where fit, heat density and repeat consistency are more important than a generic stock price.
Custom leads, density and sensing options
Straight or right-angle leads, high-density construction and integrated thermocouple options can be reviewed.
For OEM, replacement and repeat supply
Equipment manufacturers, mold users, distributors and importers can order from samples or confirmed specifications.
For an accurate quotation:
include quantity, destination country and any required inspection, documentation or certification.
