Koyo Giken Inc.

We design and manufacture table spot welders and related products.

Our company designs, manufactures, and sells the MYSPOT table spot welder. We have provided more than 2,200 units to 25 countries worldwide in our 38-year history. Our table spot welder with high-speed welding technology is highly appreciated at precision sheet metal production sites around the world. Our high-speed welding technology has minimized burns and strains on material surfaces, and reduced the burden of eliminating burns after welding. It has also solved the issue of creasing or twisting (sheet separation) in thin-sheet welding. This has halved the material thickness while maintaining the appearance and strength as well as reducing the weight and cost.

MYSPOT table spot welder and related product design and manufacturing

[Strength of products/technologies]
Our high-speed welding technology can raise the interface temperature to 1,530 ºC within a time as short as 0.01 seconds. The instantaneous heating finishes melting between materials before heat is conducted to the surface of the material to be welded. This technology minimizes burns and strains on material surfaces and reduces the burden of eliminating burns after spot welding. This technology also solves the issue of sheet separation (creasing or twisting) in welding thin sheets (t 0.5 to 1.0). The material weight and cost can both be reduced at the same time.

[Representative's message]
We aim to be a small-sized large company. This is based on our belief that we can do more valuable jobs than large companies because our company is small. Working on the global stage will not be a dream if we make the most of the world’s infrastructure while putting our heads together to do worthwhile jobs. We will continue to transmit our spot welding technology from Sagamihara to the world.

[Company structure for market development/overseas expansion]
About 15% of our workers can handle matters in foreign languages. This is why we quickly answer even overseas inquiries.
