CASTING

The high degree of homogeneity inherent in the horizontal continuous casting process results in superior metallurgical properties in the finished products. Contemporary casting technology gives us the capability of producing long continuous unwelded coils of precise chemical composition. Computer-controlled direct reading spectrometer aids in monitoring the chemistry of the melt. Surface imperfections of the cast strips such as oxides etc. are then removed with the off-line milling machines.

COLD ROLLING

Our Griset, Achenbach Mino, and MKW mills can roll down the strips to a thickness as thin as 0.03 mm. Our automatic gauge control system ensures minimal strip thickness variation. The strict control of various parameters imparts excellent shape, surface finish, and mechanical properties to the strip.

ANNEALING AND PICKLING

Our annealing equipment (Ebner, Wesero and Radcon) is capable to meet the explicit metallurgical requirement of the customers. Alloy, strip thickness, final product specifications, and other factors are considered while applying the annealing schedules to semi-finished or finished rolled strips. Our 100 % Hydrogen furnaces are fitted with automatic controls for consistent batch-to-batch results. Our world-class Junker DAP (Degreasing, Annealing and Pickling) line provides uniform characteristics.

SLITTING and PACKING

Our slitting equipment like Sundwig, Guida, Ruesch having loop slitter provides closer widths, bow-free, burr-free and camber-free products. The up-coiler has the versatility to engage arbours of different diameters to meet the coil density and the inner diameter requirements of the customer. The slit coils are then placed in sea-worthy packages.

ELECTROPLATING

Electroplating creates a protective barrier to reduce friction and prevent tarnishing of a surface as well as protecting surfaces from wear and tear by applying a thin, durable metal coating.

Our dedicated Electroplating line has the capability to coat Tin Matte and Tin Bright, copper and Nickel on Brass material with a reflow process as per customer requirements.

PRESS SHOP

We have a dedicated Press Shop which houses cupping presses and allied infrastructure to manufacture Cartridge case and Bullet Jacket Cups for Small Arms Ammunition. We produce brass cups in various calibres viz. 9mm, 10mm, 5.56mm, 0.0338, 7.62mm, 44mg, 12.7mm (0.5 cal), and other customized calibres.
