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.
This is a revolutionary cartridge heater that prevents insulation degradation caused by moisture absorption.
This is a heater designed to be inserted into a hole provided in the metal part. It is used not only for mold heating in plastic processing machines but also in automatic packaging machines and other applications. 【Features】 ● The heater itself is sufficiently electrically insulated and has a structure that allows for safe use. However, as a characteristic of the insulating material, its insulation properties may decrease at high temperatures or deteriorate due to moisture absorption in high-humidity environments. To address the issue of insulation degradation, we have developed a revolutionary cartridge heater that uses "water-repellent magnesia" to solve the problem of insulation reduction caused by moisture absorption.
Our original cartridge heater, developed with high technical expertise, boasts high insulation, high durability, as well as high precision and high power density!
Cartridge heaters are products that are often used for mold heating in injection molding machines. For users who are troubled by inconsistent mold temperatures, we offer cartridge heaters with excellent heat uniformity. These uniform heat cartridge heaters can also be finely adjusted to match the user's specific usage. Additionally, for users who require ultra-high temperature specifications, we can propose heaters that can minimize the clearance with the mold to an extreme level. The outer diameter tolerance of the heaters can be accommodated within a maximum of ±0.02 mm. Furthermore, all our products are made to order, and we can accommodate quantities starting from just one piece. 【Features】 ■ High insulation performance using "water-repellent magnesium" ■ Capable of supporting high power density (up to 30W/cm²) ■ High precision outer diameter tolerance for heaters (±0.02 mm) ■ Excellent heat uniformity ■ Custom manufacturing tailored to user specifications
Development of energy-saving cartridge heaters
With "energy conservation" as a keyword, we are actively engaging in joint research and development with various companies to respond to customer needs, while also advancing the development of our original products.
A cartridge heater (single terminal heater) is a heater used by inserting it into the mold section.
Features of Cartridge Heaters (Single Terminal Heaters) 1. There is no localized heating, the temperature distribution of the heating element is uniform, and the heat dissipation rate is high. 2. Depending on the application, 3 to 6 heating wires can be used, and the heating wires themselves have low thermal load. 3. Due to the processing method, high wattage can be accommodated in a small space, enabling high-temperature heating while also ensuring a long lifespan. 4. The heating wire, insulation material, and outer tube are integrated through pressing or swaging, making them particularly robust. By offering products that can accommodate various designs, we provide satisfactory products by allowing for designs that are suitable for our customers' usage methods.
A compact rod-shaped heater that heats air (gas).
The "CTA type" cartridge heater is a compact, rod-shaped heater designed to heat air and gas. It is ideal for applications such as duct heaters, heating devices, heat sources for industrial equipment, and heating of air and other gases. It can also be applied to shell-type heaters integrated into casings. 【Features】 ○ Ideal for situations where there are constraints on the dimensions of containers or installation locations and where a compact heater is desired. ○ Best suited for heating gases in piping with low flow rates. ○ Superior in terms of electrical safety, pressure resistance, and applicability to various atmospheres compared to heaters with exposed nichrome wire. For more details, please contact us or download the catalog.

The "CTL type" cartridge heater for liquid heating is a compact rod-shaped heater designed to heat liquids. It is ideal for situations where there are constraints on the dimensions of the container or installation location and a compact heater is desired. 【Features】 - Can be used for heating water, oil, and various chemical solutions - Can also be applied to shell-type heaters integrated into casings For more details, please contact us or download the catalog.
There are many installation methods for cartridge heaters! They are suitable for industrial equipment, inspection devices, and analytical instruments.
The "CTM type" is a cartridge heater designed for low voltage applications such as 24V and 48V. This heater is made to order. It is suitable for use in equipment such as commercial devices, inspection equipment, analytical instruments, and research and experimental apparatus for heating, maintaining temperature, and low-temperature measures at low voltage. There are various mounting methods for the cartridge heater, including "flanged waterproof type," "flanged with spring," "round flange," and "L type," among others (some options). 【Specifications】 ■ Power supply: 24V ■ Lead wire: Glass braided insulation 200mm ■ Outer diameter tolerance: + 0.1mm *For more details, please refer to the PDF document or feel free to contact us.

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.
【Short Delivery Time】Immediate delivery is possible with items in stock. Designed for high temperatures for long life. Special specifications for flanges, L-shaped caps, and lead wires are also available.
The high-temperature cartridge heater manufactured by Ramarod is a high-watt density (W/cm²) cartridge heater that enables long life even at high temperatures, as a result of years of research. It uses Incoloy material for the sheath and has Incoloy end discs welded at the cartridge heater terminals, with the mouth treated with LavaSeal (special volcanic sealing), allowing for uniform and precise heating at medium and low temperatures, as well as maintaining a continuous sheath surface temperature of up to 800°C. The RAMAROD cartridge heater has passed the stringent regulations of various industries and institutions, and its production process complies with the regulations of both state and federal governments in the United States, while also being approved for use by NASA, the space industry, and the nuclear industry.
