Factory Custom Industrial Rod Cartridge Heater for Mold Immersion Heating

Cartridge heaters is consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention. The heating wire inside which is wound onto a ceramic core.

The number of coils varies depending on the power. and provide a great uniform distribution of heat, which considerably increases the long life of the heater as well as prevents the oxidation of the heater wire even at high temperatures.

The solids, liquids, and gases need to be heated by cartridge heater, transmit heat quickly by conduction if the producer of the heat(the cartridge) is in direct contact with the heat sink(any solid, liquid, or gas). Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc they are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries.

Apart from our broad standard range we also develop and manufacture cartridge heaters according to your special demands.

Termination Options of Cartridge Heater

Swaged-in Flexible leads

Swaged-in flexible leads, with silicone-fiberglass insulation, are recommended for applications in which the leads must be bent at the exit point from the heater.
Unless longer length is specified, 250mm(10 in.) leads are supplied.
Heaters 150mm(6 in.) or shorter generally have a 6 mm(1/4 in.) no-heat section. Heaters up to 250mm(10 in.) require a 25mm(1 in.) no-heat section. Heaters greater than 250mm may require more than a 25mm no-heat section. To order, please specify swaged-in flexible leads.

Right Angle leads

Right angle leads are used in applications with a high degree of flexing and when space limitations are critical. Lead wires exit at a 90° angle through the side of the heater sheath.

Right angle tube may be necessary on certain constructions.To order, specify right angle leads and lead length.

Diameter mm	Min No-Heat Length mm(in.)
6.5	15 (9/16)
8.0	15 (9/16)
10	17 (2/3)
12.5	18 (11/16)
16.0	20 (3/4)
20.0	21 (13/16)

Stainless Steel Braid

A stainless steel braid is designed to protect leads from abrasion against sharp edges.
When the leads exit straight out, the braid is swaged into the no-heat section of the heater. When the leads exit at a right angle, a crimp connector is used to attach the braids.
Unless otherwise specified, leads are 250 mm(10 in.) and the braid is 200 mm(8 in.) long. To order, specify either straight or right angle stainless steel braid, lead length and no-heat section.

Stainless Steel Hose

Stainless steel hose provides the best protection against abrasion from sharp edges or abrasive equipment. It also offers ease of handling and wiring in abrasive environments.
When the leads exit at a right angle to the heater, the hose is silver soldered to the sheath. Unless otherwise specified, leads are 250 mm(10 in.) long and the hose is 200 mm(8 in.) long. To order, specify stainless steel hose, lead length and no-heat section.

Galvanized Conduit

Galvanized conduit equals stainless steel hose in its abrasion protection.
The conduit is attached with a 90° elbow copper coupler, which overlaps the heater sheath. Unless specified, 200 mm(8 in.) conduit is supplied, leads are 50 mm longer than the conduit. To order, specify galvanized conduit, lead length and no-heat section.

Ceramic Bead Insulation

Ceramic bead insulation protects the leads from high temperature ambients above 450°C(840°F). The beads fit over solid conductors and are extended long enough to reach a cooler area where flexible wires can be attached. To order, specifyceramic beads and length, and additional lead length.

Flanges for the cartridge heater

Stainless steel flanges are a convenient mounting method as well as a way to position a heater within an application. Flange style according to customer requirements . These flanges can be located in any no-heat section of the heater sheath. To order, specifyflange, flange size and location.

Immersion Cartridge Heaters:

(For liquid immersion heating applications, use brass or stainless steel threaded bushing.)

The size of threaded bushing is matched according to pipe diameter. The specifications of threaded bushing include G thread, NPT thread, BSPP thread, etc.
Please contact us for specific order.

How to install cartridge heater

make a hole in the section that is to be heated
ream a smooth hole for contact and for better heat transfer
extend the hole through the section so that the unit can be driven out if you should need to remover it.
if making a through hole is impossible ,increase the size of the hole without exceeding the tolerances
Reduce the vibration and flexing of the lead wires to prolong service life
prevent contamination from liquids by protecting the end of the heater

When ordering Cartridge Heaters, please specify the following information :-
1. Type of Cartridge Heater(please refer to Termination Options).
2. Diameter of Cartridge Heater.
3. Overall length for a straight Cartridge Heaters.
4. Wattage & Voltage
5. Lead type(glass fibre / PTFE) & lead length.
