Express Prototype

Introducing our strengths! We can accept prototypes solely for shape and functionality verification.

Kyo-Wa Hearts Co., Ltd. accepts "express prototypes" and contributes to accelerating our customers' development speed from prototyping to mass production. In particular, we specialize in the production of thin sheet spring products, which are difficult to simulate in terms of springiness, sliding properties, and durability. Additionally, when you request a prototype of a flat spring, we can quickly transfer data thanks to our rich variety of acceptance formats. Please feel free to contact us.
