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.
It is possible to put a large electrical capacity into a small-sized heater! It can be used for applications such as molds, dies, and liquid heaters.
A "cartridge heater" is a heater that contains a heating wire wrapped around an MgO block inside a metal pipe, filled with high-purity magnesia, with lead wires drawn out from one side of the metal pipe. When compared to a sheath heater of the same length, a cartridge heater can be designed for higher capacity, allowing for high-capacity specifications even in shorter dimensions. It can be used in applications such as molds, dies, liquid heaters, semiconductor manufacturing equipment, and machinery for the food industry. 【Features】 - Contains a heating wire wrapped around an MgO block inside a metal pipe. - Filled with high-purity magnesia, with lead wires drawn out from one side of the metal pipe, allowing for space-saving installation. - Capable of high-capacity design in shorter dimensions compared to sheath heaters.

![[Case Study] Metal Frame Heater FW Type](https://image.mono.ipros.com/public/product/image/76e/2000366882/IPROS82168367984058564412.jpeg?w=280&h=280)
Recommended for those who want to use it in a clean environment! Case study of the surface heater "FW type".
We would like to introduce a case study of the 'Metal Frame Heater,' which can operate at temperatures up to 900°C and is designed without ceramic fiber, making it suitable for use in clean environments. Due to the inability to use insulation materials in vacuum furnaces and to meet the conditions for uniform heating, we proposed the planar heater model "FW type," which was successfully implemented. The design needed to prevent vacuum discharge, and we were able to accommodate details such as fixing to the case and TC holes according to the customer's requests, which made them very happy. Additionally, we have a track record of delivering FW heaters for standalone testing. They can also be used for testing purposes, serving as a basis for determining whether they can be adapted to the customer's equipment. 【Product Introduced】 ■ Ceramic Fiberless Type (FW Type) ・Maximum Operating Temperature (inside furnace): 900°C ・Wall Watt Density: up to 10w/cm² ・Shape: Rectangular Plate ・Manufacturable Dimensions: W100×L250×t30mm and above *For more details, please refer to the PDF document or feel free to contact us.

Most of the initial problems have been cleared! Here are examples of how we responded to requests to stabilize quality!
We will introduce a case study on the review of the glass material heating method. There was a challenge in stabilizing quality due to the volatilization caused by moisture and CO2 when heating with the currently used burner. By replacing gas heating with electric heating, most of the initial problems have been cleared. Moving forward, we aim to establish conditions that exceed those of burner heating and will address the remaining challenges one by one. 【Case Study】 ■Challenge: There is a need to stabilize quality due to volatilization caused by moisture and CO2 when heating with the currently used burner. ■Proposal: Replacement of gas heating with electric heating. ■Results ・Most of the initial problems have been cleared. ・Moving forward, we aim to establish conditions that exceed those of burner heating and will address the remaining challenges one by one. *For more details, please refer to the PDF document or feel free to contact us.

■What is a Cartridge Heater A cartridge heater is a pipe-type heater widely used in molds, packaging machines, molding machines, and more. It primarily consists of nichrome wire (the heating element) wound around a molded piece of magnesium oxide called a bobbin, which is then placed inside a metal pipe such as stainless steel. After filling with magnesium oxide powder, the heater undergoes a squeezing process to increase the filling density of the magnesium oxide, allowing it to release more heat to the outside of the heater 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. ■Types of Cartridge Heaters The types of cartridge heaters include flanged cartridge heaters, threaded cartridge heaters, small-diameter cartridge heaters, high-temperature cartridge heaters, L-shaped cartridge heaters, side lead type cartridge heaters, two-circuit cartridge heaters, cartridge heaters with built-in thermocouples, copper pipe cartridge heaters, coarse and fine winding (balanced winding) cartridge heaters, and various heaters for plastic molding machines and industrial machinery.
