■What is a Cartridge Heater? A cartridge heater is a pipe-type heater widely used in molds, packaging machines, molding machines, and other applications. It primarily consists of a nichrome wire (heating element) wound around a molded magnesium oxide material called a bobbin, which is then placed inside a metal pipe such as stainless steel. After filling with magnesium oxide powder, a squeezing process is performed to increase the filling density of the magnesium oxide, allowing the heater to release more heat to the outside of the pipe. This makes it an excellent heater. The principle of the cartridge heater is based on resistance heating, as it uses nichrome wire as the heating element. ■Benefits of Using SUS Flexible Cartridge Heaters One of the characteristics is that they are protected from scratches due to being shielded from the outside by lead wires. Regarding the internal wiring, it can be selected based on factors such as ambient temperature.

It primarily consists of a nichrome wire (heating element) wound around a molded object made of magnesium oxide, placed inside a metal pipe such as stainless steel. After filling it with magnesium oxide powder, it undergoes a squeezing process to increase the filling rate of the magnesium oxide, allowing the heater to release more heat to the outside of the pipe. The principle of the cartridge heater is based on resistance heating, as it uses nichrome wire as the heating element. ■Advantages of Using L-Shaped Cartridge Heaters Since the lead wires are oriented in an L direction relative to the heater, there is no need to forcibly bend and route the lead wires. This helps prevent wear on the lead wires. Additionally, because they are oriented in the L direction from the start, if there is no space near the heater's sealing area, it is possible to route the electrical wires in that space.

This is a heater that is used in various applications such as firing furnaces, heating furnaces, and annealing furnaces. It is a lightweight and compact ceramic fiber heater that incorporates a heating element (heating body) into a flux board. There may also be machining of grooves, holes, and coatings on the ceramic fiber board. Its features include efficient infrared heating with minimal waste from electricity, and the ability to design shapes and sizes freely. Additionally, it is characterized by its quick response as a heater. Besides industrial furnaces, it is also used as a board heater for semiconductor devices.

• Other machine elements

Thanks to the flexibility of the micro heater, it can be mounted on curved surfaces without the need for bending processing. We have planned standard products with diameters ranging from φ2.4 to φ4.0. 300W φ2.4 3840L watt density 1.04 300W φ2.4/5890L watt density 0.68 600W φ3.2/5310L watt density 1.12 600W φ3.2/11120L watt density 0.53 900W φ3.2/7470L watt density 1.20 900W φ4.0/12220L watt density 0.59 It is also possible to design products outside of the above specifications.

• Aluminum heater

The "immersion heater" is a type commonly used for preheating holding furnaces. Our company has a proven track record with aluminum immersion heaters and provides reliable heaters and thermocouples. This is a direct heating type aluminum heater with an integrated thermocouple. It is used for maintaining the temperature of aluminum melt in holding furnaces, managing outlet temperature, and maintaining the temperature at the tapping point. Please use aluminum heaters to maintain the temperature of the melt in the crucible. 【Example Specifications for Aluminum Heaters】 ■ Type for Preheating Holding Furnaces 【Structure of Aluminum Heaters】 The heating element of the aluminum immersion heater uses nichrome wire. The protective tube employs silicon nitride, which is most suitable for molten aluminum. For safety, it is equipped with an integrated thermocouple for overheating prevention.

**Features of the Micro Heater** - The thin wire diameter makes installation and wrapping easy. - Depending on the specifications, there are few issues when used in a vacuum. - The micro heater offers a wide range of resistance values. - Variations can also be increased. - We can accommodate requests for special resistance values. - It can fit into spaces where conventional heaters could not. The "Micro Heater with Non-Heating Section" is a product made using Sanko's unique method. Its outer diameter is very thin, making installation and wrapping easy, and if it has a non-heating section, there are few issues when used in a vacuum. (The non-heating section is between 100 mm and 1000 mm.) It can be used with heating plates for vacuum applications.
