[Notice] We have made an investment in the latest Aizawa-manufactured press brake!
In manufacturing, we don't immediately create molds for mass production; instead, we first produce a few prototypes, typically around 100. What we need for this is the press brake. It is a sheet metal machine used to bend thin sheet metal materials. The features of this machine include high repeatability precision, fine adjustment mechanisms that can be tailored to the product, easy clamp for one-touch mold attachment, quick change, CAD/CAM integration, and the capability for internet connectivity for IoT use! Trust Kyo-Wa Hearts not only for mass-produced items but also for prototypes!
Explaining the key points in selecting materials for springs. Please feel free to consult us about design concerns or prototypes!
