The "Ceramic Band Heater" uses ultra-ceramic insulators and is a heater that can be used at high temperatures. Because it uses ultra-ceramic insulators, there is almost no decrease in insulation resistance around 680°C, providing high high-temperature insulation characteristics and good thermal conductivity. In addition to heat conduction from the insulator, the axial heat from infrared radiation from the heating wire is added, allowing for uniform heating of the heating cylinder. We also manufacture various other ceramic heaters, so please feel free to contact us. 【Features】 ■ Uses ultra-ceramic insulators ■ Almost no decrease in insulation resistance ■ High high-temperature insulation characteristics ■ Good thermal conductivity ■ Allows for uniform heating of the heating cylinder *For more details, please refer to the catalog or feel free to contact us.

At Square Co., Ltd., we design and manufacture long nozzles for molding machines according to user requests. In general coating processes, only about twice the inner diameter can be accommodated, but our nozzles are fully hard-coated on the entire internal hole. We can reduce the peak pressure during injection and design the heater to be optimal for those usage conditions. Leave the design and manufacturing of nozzles to us. 【Features】 ■ Excellent corrosion and wear resistance ■ Designed and manufactured according to user requests ■ Hard coating applied to the entire internal hole ■ Reduces peak pressure during injection ■ Optimal design *For more details, please refer to the catalog or feel free to contact us.

• Other factory equipment

At Square Co., Ltd., we manufacture sprue bushes. Eliminating the sprue has been done for a long time, but in recent years, the diversification of products has progressed, and as a result, many companies are using their own uniquely developed resins, which requires more advanced molding techniques. Therefore, we respond to each user's requirements with short delivery times and optimal designs, including hard coating. Please feel free to contact us. 【Features】 ■ Short delivery times ■ Optimal design ■ Responsive to user needs *For more details, please refer to the catalog or feel free to contact us.

The "Square Coil Heater" is a heater that significantly improves thermal efficiency because the heater coil makes surface contact with the heated object. The nichrome wire inside the heater sheath is processed into a spiral shape using a unique method, which greatly increases the amount of heat generated per unit length of the sheath. A non-heating zone is provided at the connection between the heater and the lead wire, eliminating heating issues at the connection point. Additionally, the coil pitch (tightness and winding density) can be freely adjusted according to heating conditions, so please feel free to contact us. 【Features】 ■ Significantly improved thermal efficiency ■ Spiral shape ■ Greatly increased heat generation ■ Presence of a non-heating zone ■ Elimination of heating issues at the connection point *For more details, please refer to the catalog or feel free to contact us.

The "BS Flexible Square Heater" is a heater developed for small heat plates that are not possible with AL flexible heaters. With a minimum bending radius of 15mm, it makes the design of small heat plates easier. Additionally, since it has a single terminal, designing circular heat plates (spiral type) is also made easier. Despite having a cross-section of 4.2mm, it offers high capacity. No filler is required for the heater's corner grooves. 【Features】 ■ Compact ■ Easy design of small heat plates ■ Easy design of circular heat plates (spiral type) ■ High capacity ■ No filler required *For more details, please refer to the catalog or feel free to contact us.
