栃木精工 List of Products and Services

In recent times, as magnetic measurement analysis and evaluation have become widely used in various industries, the need to properly block the influence of surrounding magnetic fields has increased. "Permalloy" is a soft magnetic material with a very high permeability, primarily composed of nickel. Utilizing its excellent properties, it reduces the influence of external magnetic fields and enables high-precision measurements within the shield. Additionally, in the case of measuring devices that generate strong magnetic fields, it is necessary to similarly implement magnetic shielding to prevent external influences; in such cases, permalloy shield boxes demonstrate sufficient performance. 【Features】 ■ Uses domestic material from a manufacturer with very high permeability, capable of attenuating even fine magnetic fields. ■ Achieves shielding characteristics and sizes tailored to specific purposes, such as blocking geomagnetic and external magnetic fields. *For more details, please feel free to contact us.

At Tochigi Seiko Co., Ltd., we perform various processes in the manufacturing of our products, including magnetic annealing (high-temperature annealing), bright annealing (BA annealing), and softening annealing (low-temperature annealing). Annealing is a process that involves heating and holding the material at the recrystallization temperature, followed by slow cooling. The purpose of this heat treatment is to remove residual stress, soften the material, improve machinability, enhance cold workability, and adjust the crystal structure. Additionally, we also accept orders for annealing processes only, so please feel free to consult with us. 【Features】 ■ The heating temperature and cooling method vary depending on the material and purpose. ■ We can also accept orders for annealing processes only. *For more details, please refer to our catalog or feel free to contact us.

Tochigi Seiko Co., Ltd. has been involved in the manufacturing process of "sterilized medical devices" using EOG (ethylene oxide gas) and gamma-ray sterilization, and has confidently provided numerous medical devices to various medical institutions with responsibility and assurance. Unlike gamma-ray or electron beam sterilization, EOG is less likely to cause material degradation, can sterilize most materials, has high penetration power, and allows for sterilization of cardboard boxes (excluding completely sealed containers). Additionally, our company also accepts contracts for EOG sterilization processing only, so please feel free to consult with us. 【Features】 ■ No material restrictions ■ No shape restrictions ■ Flexible delivery times according to your requests *For more details, please refer to our catalog or feel free to contact us.
