May 13 (Wednesday) to May 16 (Saturday), 2026: Invitation to exhibit at 'EMIDAS Manufacturing Business Meeting 2026 in Bangkok'
Kyo-Wa Hearts Co., Ltd. will be exhibiting at the 'EMIDAS Manufacturing Business Meeting 2026 @ Bangkok' held in Bangkok, Thailand. This is an exhibition and business meeting primarily focused on "small and medium-sized manufacturing-related companies," held annually in Thailand and Vietnam. It is a trade show that boasts a top-class number of visitors from various countries, and matching through advance business meeting applications is possible. This time, we will be exhibiting in Bangkok, Thailand. We sincerely look forward to your visit.
We will thoroughly explain points regarding the use of stainless steel as a material for springs and joining technologies! *Free materials are currently being offered.

[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!
