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.
