CONTROLLED SURFACE SYSTEM
Overview
A surface engineered around the part.
Micro-porous oxide is developed under controlled bath chemistry and precisely dyed before sealing to create expressive finishes that remain engineered for demanding service environments.
Our process planning considers alloy series, machining condition, dimensional sensitivity, racking position, visual zones and service environment before production begins in our Rajkot plant.
