Even during the fitting, it should be 0.08 or less. It should not come apart when dropped from a height of 20 cm.

The material of the small hole is stainless steel, with a thickness of 0.15, and a flatness of 0.08 or less, intended for use in shield cases. The thickness of the dowel is 0.2, the material is stainless steel, the flatness is 0.08 or less, the width is 0.8, and the bending height is 1.4. When these two are combined, they will not come apart even when dropped from a height of 20 cm, maintaining a flatness of 0.08 or less during engagement. Kyowa Hearts specializes in processing thin, small, and fine plate springs, from handmade prototypes to precision press processing using precision progressive dies. We are particularly skilled in the production of compact plate springs for mobile phones, computers, connector parts, and more. *For more details, please contact us or refer to our catalog.*

Our company specializes in fine, complex, and precision press processing. *We also sell molds! We can handle everything from examining the shape of customer parts, prototyping, mold manufacturing, to mass production processing. 【Our Expertise Developed Over Time】 1. Deep drawing and flat spring processing 2. Fine processing (plate thickness: 0.03) 3. Complex shapes and high-precision bending processing 4. Processing of difficult materials (titanium, shape memory alloys, magnesium alloys, etc.) 【Proposal Power Supporting Quick Start-Up】 Many customers consult us during product development, asking if certain processing is possible, seeking advice during the conceptual stage, or wanting to start with prototyping. In the development phase, we provide comprehensive advice on material and shape decisions, as well as secondary processing, to fully support the launch of new products. We also believe that "refined products are a testament to stable quality," and we enter mass production only after sufficient adjustments (taking extra care). 【Efforts in In-House Product Development】 We are also engaged in in-house product development utilizing our cultivated precision press processing technology. We have developed a new type of file for binding documents, called "Nuke," which allows for easy insertion and removal of documents from the center, attracting attention as an item that enhances office productivity.
