Products including Tsubaki insulators and bushing insulators.

Based on years of technology and experience, we will propose insulator manufacturing tailored to your needs.

We would like to introduce the areas of expertise and capabilities of Gokai Co., Ltd. We own a dedicated kiln for small-lot production, including prototypes, which allows us to complete projects at a lower cost and with shorter lead times compared to using standard-sized kilns. Additionally, we can manufacture sizes up to approximately 600mm. While we cannot produce very large sizes, we can mass-produce smaller sizes down to about 1mm. 【Areas of Expertise and Capabilities】 ■ We can accommodate small orders ■ We excel in small sizes ■ We also accept prototype requests ■ We can handle typical alumina, as well as steatite, cordierite zircon, and standard porcelain ■ We can serve customers nationwide ■ We offer proposals that lead to cost reduction and shorter delivery times *For more details, please refer to the PDF document or feel free to contact us.
