Company information
Since our establishment in 1928, we have been engaged in spring manufacturing with "quality, cost, and delivery" as universal challenges. We manufacture all products, particularly focusing on "precision small springs" and "micro springs," which are difficult to produce and require complex processing, in a fully integrated in-house system.
