Eliminate burrs through mold manufacturing that meets the product requirements sought by customers! A case study from an electronic components 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 designs parts from the stage of design to achieve narrow clearances, so we can custom-manufacture both manufactured and purchased parts. As a result, we can produce molds that meet the product requirements sought by customers. [Case Overview] ■ Customer's Industry: Electronic Components Manufacturer ■ Consultation Content: Desire to cut thin products sharply ■ Proposed Solution: Ultra-small clearance die ■ Technology Used: Improvement of mold structure and part precision ■ Outcome: Successfully eliminated previously unresolved burrs. *For more details, please refer to the related materials or feel free to contact us.

I have summarized the basic content regarding the impact of clearance variation due to plate thickness and the reduction of running costs achieved through uniform clearance. * * Clearance (CL) refers to the gap between the punch and die of a mold. CL is set at plate thickness × 4-7%. The range of 4-7% is determined by the plate thickness. In the PDF document, we introduce: - Examples of clearance settings by plate thickness for t=0.1mm/t=0.05mm/t=2.0mm - The impact of uneven clearance by plate thickness - The effects of achieving uniform clearance Table of contents: - What is clearance - How to set clearance - Examples of clearance by plate thickness - Effects of achieving uniform clearance

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 machining hard materials using electrical discharge machining, micro-cracks caused by thermal effects occur during processing. These cracks penetrate to a depth of about 20μm, and no matter how much polishing is done to create a smooth surface, they remain. These cracks can lead to wear in punches that are subjected to high loads. In contrast, milling does not produce any micro-cracks at all. Milling tools can go down to R0.1, providing a very high degree of flexibility in machining shapes. [Case Overview] ■ Customer Industry: Precision electronic components manufacturer ■ Inquiry: Wanted to improve the lifespan of hard material 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.
