Bore fit and conductive heat transfer
Cartridge Heater L-type: Install the active sheath in a close-fitting, clean bore. Specify bore diameter, tolerance and heated length together; excessive clearance increases sheath temperature and slows heat transfer.
Record the lead exit, cold end and removal access before the tool is machined. Locate the control sensor near the heated zone without placing it directly against the resistance element.
For Cartridge Heater L-type, request the missing voltage, power and finished dimensions before calculating current, selecting a supply or fixing the mounting pattern.
The archived configuration for Cartridge Heater L-type lists Resistance heating wire: NiCr 80/20 wire; Length tolerance: ±1 mm; Diameter tolerance: ±0.02mm. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For Cartridge Heater L-type, send the supply, continuous and peak temperature, mounting drawing, lead exit and quantity. Include the heated medium and control method so the quoted configuration can be checked against the actual duty.
Application and reference configuration
Molds, dies and conductive tooling. The final suitability of Cartridge Heater L-type depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

Internal wiring port section of the heating tube does not adopt the terminal connection mode,Making it have high temperature resistance and strong mechanical properties.
The port part of the heating tube adopts terminal connection mode Is resistant to high temperature and works in the heating medium which can not conduct wiring at both ends.

Core wire selection: The core wire is the heating element of the cartridge heater and is usually made of nickel-chromium or iron-chromium alloys. The wire is selected based on the required wattage and operating temperature of the cartridge heater.
Coil winding: The core wire is wound around a ceramic or metallic core to create the heating element. The number of turns and the diameter of the wire are determined based on the desired electrical resistance and watt density of the heater.
Core assembly: The heating element is inserted into a metal sheath, which is usually made of stainless steel or Incoloy. The ends of the core wire are welded or crimped to lead wires that will provide power to the heater.
Sealing and insulation: The ends of the metal sheath are sealed with ceramic or epoxy material to prevent moisture and contaminants from entering the heater. The entire assembly is then insulated with magnesium oxide powder to improve heat transfer and electrical insulation.
Finishing: The cartridge heater is cut to the required length and the lead wires are attached to terminal blocks or connectors. The heater may be coated with a protective layer to resist corrosion or abrasion.
Testing: The finished cartridge heater is tested to ensure that it meets the required specifications for electrical resistance, wattage, and insulation resistance.
