Small Radius Mold Insert Machining: Protecting Corners Before Polishing
Small radii and sharp internal corners can easily change during polishing. This article explains how machining strategy, tool selection, mirror EDM and controlled finishing help protect critical corner 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.
