High watt cartridge heater enables rapid heating due to its high watt density, allowing for high-cycle molding.
Due to new materials such as engineering plastics and thixotropic materials, increasingly high temperature management is required for mold temperatures. If it's high wattage, it is indeed the Watlow Corporation from around the world. Watlow's cartridge heaters are distributed globally with unique model numbers.
We provide standardized band heaters. The average watt density is 5 w/cm². We also accommodate custom orders outside of standard products.
Side pull type Vertical pull type Rivet type High adhesion type
Ideal as a gate bushing heater that is resistant to high temperatures and also strong against resin coating.
Compared to band heaters, it has a longer lifespan at high temperatures and excellent insulation properties. Since it makes surface contact with the heated object, the thermal efficiency is significantly improved. There are four types of sheath cross-sections: 4.1 square, 3.5 square, 2.5x4.0 rectangular, and 2x3 rectangular. The connection part with the lead wire is a non-heating section, making it less likely to experience disconnection. It is also possible to incorporate a thermocouple (J or K).
High thermal conductivity, ideal for heating the manifold.
- It is a flexible heater that can be easily bent with hand strength. - It has a higher thermal efficiency compared to cartridge heaters and offers excellent temperature distribution in the manifold. - No inorganic hardener is required for fixing the heater. - It is a product with lower power consumption compared to other materials.
Bendable heater
- With excellent flexibility, it can be bent into free shapes and can be installed in narrow spaces or complex shapes. - We will manufacture it to your desired length (depending on the desired sheath length, number of bolts, wattage, and quantity). - When requesting a quote, please specify the sheath diameter, sheath length, number of bolts, wattage, quantity, lead wire length, and operating temperature in advance.
TEMPCO's band heaters use a special insulator (mica), making them excellent products for high-temperature resistance.
1. This is a high-watt density band heater of the NHW (stainless steel insulated lead wire type) and NHL (fiberglass insulated lead wire type). MAX temperature: 450°C, recommended watt density: 8.5W/cm² or less. 2. We maintain a wide range of standard products with a minimum inner diameter of 22mm to a maximum inner diameter of 70mm as manufacturer standard stock. 3. The tightening band screw part has a compact design, allowing for a smaller mold engraving size. 4. Custom sizes can also be manufactured, so please contact us.
It is ideal as a band heater for hot runner nozzles of multi-cavity precision molds.
It is optimal as a band heater for hot runner nozzles of multi-cavity precision molds. The heating element is wound in a coil shape for direct heating, resulting in no heating unevenness. It heats up quickly and is highly resistant to impact. The inner diameter can accommodate up to 63.50mm.
The ring heater is a heater designed for external heating of hot runner nozzles. A sheath heater is embedded in a stainless steel tube.
Features: Simple and compact, and strong against resin coating. Can achieve high wattage. Has minimal heat unevenness. Excellent corrosion resistance and low adhesion to the heated object. Can also accommodate export use (rated 240V). Types: There are FS type and FL type. Please refer to the details below. - Complete tubular thermocouple included. - Complete tubular thermocouple not included.
Aluminum casting heater considering thermal efficiency
We manufacture and deliver aluminum cast heaters considering watt density and thermal efficiency in a short lead time. Please place your order using the quotation request form or order form on the back. We also accept custom specifications (shape and size), so please specify with drawings, etc.

The split-type structure features a unique design where the sheath part is separated like two legs.
- This is a high-watt cartridge heater of the split sheath type, which fundamentally differs in manufacturing method from a typical cartridge heater. - The split type structure features an innovative design where the sheath parts are separated like two legs. - Since there is no non-heating section at the tip of the heater, it is effective for heating specific areas. - Due to thermal expansion, the two sheath parts expand outward, allowing them to closely adhere to the insertion hole of the mold, enabling high-temperature heating at low temperature settings. As a result, it has a lifespan 2 to 5 times longer than that of a standard cartridge heater. - Because the two sheath parts expand independently, warping does not occur, making it easy to attach and detach. - It can also be manufactured for industrial voltages (200V–240V) and household voltages (20V–120V). - Additionally, it is possible to incorporate an external sheath sensor in the gap between the two sheath parts, allowing for the replacement of just the sensor in case of a disconnection.
