Manufacturing Process
Controlled 4-stage melting and vertical continuous/semi-continuous casting process ensuring dense grain structure with zero central pipe defects.
Melting & Composition Charge
Pure Copper Cathodes, Zinc Ingots, Lead, and sorted brass scrap charges are weighed precisely according to target alloy specifications.
Mains Frequency Induction Furnace
Melted under protective cover to restrict zinc volatilization and ensure homogenous liquid metal distribution throughout the bath.
Vertical Continuous Casting (VCC)
Molten alloy is passed through water-cooled graphite dies, solidifying into solid cylindrical logs with a uniform fine-grain structure.
Billet Cutting & Surface Peel
Cast logs are cut to specified press length billet sizes (e.g., 500mm - 1200mm) and billet ends are bevelled for extrusion press loading.

Primary Industrial Applications
Key downstream processing and extrusion applications using solid brass billets.
Hydraulic Extrusion Presses
Direct raw material feedstock for hot extrusion presses to manufacture brass rods, hollow pipes, profiles, flats, and wire rods.
Hot Forging Press Plants
Billet cut-pieces are reheated and press-forged to produce plumbing valve bodies, water meter housings, and pipe fittings.
Plumbing & Sanitaryware
DZR brass billets are extruded into corrosion-resistant rods and tubes for potable water valves, faucets, and brass fittings.
Electrical & Switchgear Components
Extruded into high-conductivity brass profiles, earthing neutral bars, pin terminals, and transformer busbars.
Automotive Fasteners & Inserts
Extruded rods are precision machined on CNC/Automats to produce brass threaded inserts, nipples, fuel jets, and brake hose fittings.
Marine & Industrial Hardware
Naval and High Tensile brass billets are converted into corrosion-resistant shaftings, marine pump components, and heavy wear plates.
