Discuss this finishRPI / BLACK-ANODIZING
CONTROLLED SURFACE SYSTEM
Overview
A surface engineered around the part.
A premium sealed black finish balancing low optical reflectivity, uniform visual aesthetics, and robust environmental resistance across complex machined geometries.
Our process planning considers alloy series, machining condition, dimensional sensitivity, racking position, visual zones and service environment before production begins in our Rajkot plant.
