Why a Replacement Mirror Mold Insert Doesn’t Fit Like the Original
A replacement mirror mold insert can meet every drawing tolerance and still fail to fit the existing tool. Learn how seating surfaces, locating datums, pocket conditions, and drawing revisions affect interchangeability, and what to verify before ordering a replacement.
UK Medical Optical Insert Machining Case Study: 0.002 mm Tolerance & Ra 10 nm
A UK medical optics customer approached YISHUN to verify our capability for small high-accuracy inserts requiring tolerances up to 0.002 mm and Ra 10 nm optical surfaces without polishing. This case shows how we evaluated the machining, metrology and lead-time risks before the project moved forward.
