PRODUCT ENGINEERING
Bore fit and conductive heat transfer
Cartridge Heating Rod: 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 Heating Rod, request the missing voltage, power and finished dimensions before calculating current, selecting a supply or fixing the mounting pattern.
The archived configuration for Cartridge Heating Rod 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 Heating Rod, 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 Heating Rod depends on the assembled equipment and agreed operating conditions.

ARCHIVED PRODUCT INFORMATION
Description
Cartridge heaters are heating elements that are used for a variety of industrial heating applications. They consist of a cylindrical-shaped metal tube or sheath that contains an insulated heating element. The cartridge heater is usually inserted into a drilled hole in a solid material, such as metal or plastic, where it provides concentrated heat to a specific area.

Advantages
Internal wiring: high temperature resistance, uniform heating, high thermal conductivity and difficul cable fracture.
External wiring: high temperature resistance, uniform heating and high thermal conductivity.

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.
