Bore fit and conductive heat transfer
Spilt Sheath Cartridge Heaters: 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 Spilt Sheath Cartridge Heaters, request the missing voltage, power and finished dimensions before calculating current, selecting a supply or fixing the mounting pattern.
The archived configuration for Spilt Sheath Cartridge Heaters 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 Spilt Sheath Cartridge Heaters, 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 Spilt Sheath Cartridge Heaters 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.

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.

Split-Type cartridge heaterA split-type heating tube is a special-structured electric heating element. Its core feature is that the heating wire inside the tube is designed in sections, or the outer sheath adopts a split structure, with the following key characteristics:
I. Structure and Principle
Internal Split (Sectional Heating Wire): The heating wire of one tube is divided into multiple sections, each with independent lead terminals, enabling multiple independent heating circuits. For example, in the hot runner system of injection molding machines, it can achieve zoned temperature control for different areas.
Outer Sheath Split (Split Sheath): The outer sheath is slit longitudinally. During heating, it fits tightly with the mounting hole due to thermal expansion, and shrinks after cooling for easy disassembly. This design is common in mold heating scenarios, solving the problem that traditional heating tubes are "seized" in the mounting hole due to thermal expansion and contraction.
Core Advantages
Precise Zoned Temperature Control: Different heating sections can be switched on/off or adjusted for power independently, suitable for scenarios requiring high temperature uniformity (e.g., heating of extruder die heads to ensure consistent sheet thickness).
Easy Installation and Maintenance: The split sheath design allows easy insertion or removal from worn or irregularly sized mounting holes, reducing equipment downtime.
High Reliability: If one circuit is damaged, other circuits can still work. Some models (such as four-split structure) can further improve heat conduction uniformity.
Power Flexibility: Various power combinations can be achieved by connecting different heating sections in series or parallel, adapting to different working conditions.
Function:
1. Operating conditions: ambient temperature-20℃ ~ + 60℃, relative temperature <80%;
2. Electrical strength: cold withstand voltage AC work 1500V 50Hz lasts for 1 min without breakdown phenomenon;
