About the Service

Precision Hard Chrome Plating for the Extrusion Industry

Aarti Extrusiontechnik provides precision Hard Chrome Plating services for extrusion screws, barrels, dies, mandrels, and tooling. Our advanced in-house finishing process enhances wear resistance, corrosion resistance, dimensional accuracy, and surface finish, restoring components to like-new condition while significantly extending their service life.

Our hard chrome plating is especially recommended for CPVC pipe extrusion applications, where higher processing temperatures and corrosive materials demand superior surface protection. The chrome-plated, diamond-polished finish reduces wear and friction, improves material flow, and ensures consistent performance.

Our Process

A Three-Step Precision Finishing Process

Diamond Polishing

Every product is diamond polished to prepare the surface and achieve maximum finish quality.

Hard Chrome Plating

A precision hard chrome layer is applied to improve hardness, wear resistance, corrosion resistance, and durability.

Final Diamond Polishing

After chrome plating, every product is diamond polished again to achieve a mirror-like finish, superior surface quality, and optimum dimensional accuracy.
