Specializing in sales types, we have a track record of producing over 10,000 molds! Contributing to improvements in quality and productivity by resolving technical issues! * * "I want to purchase molds from two companies as a BCP measure, could you provide some consultation?" Recently, we received such an inquiry from a customer. Molds are extremely important in factories, often being critical to production; therefore, it is essential to have multiple suppliers that can respond immediately when needed. "There was a situation where if we could reduce the part size by another 2mm, we could proceed with this design, but since the mold couldn't accommodate it, we had to make significant changes to the design, causing delays." I believe there are cases where the specifications of molds become a bottleneck in quality. Recently, I have heard that some clients are requesting dual sourcing for molds. Our company has a department specialized in technical development that will do its utmost to address our customers' technical issues, so if anything resonates with you, please feel free to contact us. *For more details, please refer to the related materials or feel free to reach out to us.*

The lifespan of punches has tripled thanks to milling technology for hard materials! Here we present a case study for a precision electronic components manufacturer. When processing hard materials using electrical discharge machining, micro-cracks occur due to heat during the machining process. These cracks penetrate to a depth of about 20μm, and no matter how much you polish the surface, they remain. These cracks can cause wear in punches that are subjected to strong loads. In contrast, milling does not produce any micro-cracks at all. Milling tools can go down to R0.1, offering very high flexibility in machining shapes. [Case Overview] - Customer Industry: Precision electronic components manufacturer - Inquiry: We want to improve the lifespan of hard carbide riveting punches. - Proposed Solution: Transition from electrical discharge machining to milling. - Technology Used: Milling technology for hard materials. - Results: The lifespan of the punches has tripled. *For more details, please refer to the PDF document or feel free to contact us.*
