Centrifugally Cast
Centrifugal casting, also known as centrifugally cast, is a casting technique used to create cylindrical-shaped objects with a high degree of accuracy and structural integrity. It involves rotating a mold at high speeds while pouring molten metal into it.
AUTOMOBILE LINERS AND SLEEVES
REFRIGERATION ENGINE LINERS
HEAVY EARTHMOVER LINERS
SPECIAL PURPOSE LINERS
· All liners are made of Centrifugal
Casting and Shell Casting which gives Homogeneous structure and uniform
hardness.
· Free from casting defects like blow
holes, porosity and cracks.
· Highly qualified and dedicated
workforce to achieve zero defect components.
· Quick and in-time delivery due to
in-house hi-tech manufacturing facility.
