How to Make a High Gloss Mold Insert With Less Hand Polishing
A high gloss mold insert does not always need a long EDM-and-polish route. This article explains how better machining can reduce heavy hand polishing, shorten the process and protect critical geometry.
Mirror Mold Insert Dimensions Changed After Polishing?
Mirror polishing can improve a mold insert’s surface while quietly changing small radii, edges or critical dimensions. This article explains where that risk comes from, how we reduce the finishing burden during machining, and why critical geometry should be checked again after polishing.
How to Prevent Edge Rounding During Mirror Polishing
Sharp edges can slowly become rounded during mirror polishing, especially when heavy manual finishing is needed to remove machining marks. This article explains how we reduce polishing allowance, protect critical boundaries, divide finishing zones and verify edge geometry after polishing.
