Overview
The facility is equipped with 1750MT capacity of Water Hydraulic Hot Extrusion Press. The Hot Extrusion Press is the core strength of the Company enabling production of Mother Hollows with closer dimensional tolerances and good surface finish. Ratnamani is self-sufficient for manufacturing Mother Pipes with special chemistry.
The Hot Extruded Mother Hollows are used for manufacturing Nickel Alloy Seamless Instrumentation Tubes. The tubes are manufactured using High Speed Cold Pilger Mills, modern Draw Benches and heat treated in Off-Line Bright Annealing / Conventional Annealing furnaces.
