Eliminate burrs through mold manufacturing that meets the product requirements sought by customers! Introducing a case study from an electronic component manufacturer. When producing thin products, it is necessary to set an extremely narrow punch-die clearance, but achieving the specified clearance is difficult due to tolerance design. However, our company conducts component design from the design stage to realize narrow clearances, allowing us to manufacture both custom-made parts and purchased parts. As a result, we can produce molds that meet the product requirements sought by customers. [Case Overview] ■ Customer Industry: Electronic Component Manufacturer ■ Consultation Content: Desire to cut thin products sharply ■ Proposed Solution: Ultra-small clearance die ■ Technology Used: Improvement of mold structure and component precision ■ Outcome: Successfully eliminated previously unresolvable burrs. *For more details, please refer to the related materials or feel free to contact us.

Guaranteed shape measurement in the submicron order! We will provide quality assurance in line with the improvement of precision machining technology. We would like to introduce a case where we solved challenges by introducing a new machining center and wire electrical discharge machine to an automotive parts manufacturing company. The manufacturer was struggling with issues such as "despite producing punches and dies through three-dimensional machining to respond to the miniaturization and complexity of products, they could not produce high-precision products," and "not only were defects occurring, but they could not adequately measure shapes with conventional measuring equipment, making it impossible to guarantee precision." Therefore, we ensured shape measurement that could not be measured with conventional contact-type tracers by using a laser microscope. 【Overview】 ■ Customer's industry: Automotive parts manufacturing ■ Machining technology: Parts processing with a precision of ±2μm using the new machining center and wire electrical discharge machine ■ Quality assurance: Introduction of three-dimensional measuring instruments (Mitutoyo, OGP, TESA) and a laser microscope (KEYENCE), guaranteeing shape measurement in the submicron order. *For more details, please refer to the PDF document or feel free to contact us.
