Most of Defense jobs involve to great degree research through trial and error processes and development of prototypes.

Certain Special Purpose Machines were built based on our customer’s (Heavy Vehicles Factory, Avadi) requirements.

Some of the components such as hull of Submarine in Titanium alloy for marine applications were prototype developed by KRR and hence the manufacturing procedures established.

Radar Components for remote sensing purposes with intricate and complex shapes were developed with aid of CAD models and dies developed for accurate formation.

Heavy Shells for Marine application were formed out of special marine grade material.
