Manufacturing Process

Casting

The company has installed mains frequency channel type induction furnace from Induga and high-tech horizontal continuous casting equipment from SMS Meer- a world-renowned pioneer from Germany in casting technology, to produce superior quality billets with homogeneous chemical composition, consistent internal grain structure and good external surface. The chemical composition of billets is monitored periodically through metal analysis using optical emission Spectrometer from Germany.

Extrusion

The 2500T fully automated extrusion press from Ube, the world’s leading extrusion technology and equipment supplier from Japan, permits extrusion with a high extrusion ratio for production of extruded rods with uniform surface and core temperature and refined grain structure for further cold working. The extrusion press is fed by billets that go through billet planer; gas fired pre-heating furnace and induction heater.

Annealing and Straightening

For coil and bar annealing, the company has installed dedicated roller hearth furnace made by Daido, Japan. These furnaces are equipped with uniform temperature distribution and improved heat efficiency systems thereby providing uniformity in grain sizes and improving the mechanical working of the metal. Annealed bars of measuring in diameter between 15 mm to 40 mm are then processed through a fully automated Straightening Machine supplied by GOE of Japan.

Drawing of bars and wires

Drawn rods and bars measuring between 15mm to 43mm in diameters are produced in draw bench made by GOE of Japan, in which two bars can be drawn simultaneously. Precision brass rods measuring between 6mm to 15mm in diameter are produced in Tanisaka wire drawing machine with drawing speed of 150 meters per minute.

Rods measuring in diameter between 3 mm to 15 mm are produced by I-type Combine Drawing machines from Miyazaki that are equipped with facility for combined drawing, straightening, polishing, and double-end cutting.

Quality Assurance and Control

The company has invested in technologically advanced equipment such as Spectrometer from Spectro Germany, Instron Tensile Tester and Wilson Hardness Tester from USA, and high-magnification Metallurgical Microscope from Euromex, Holland for effective product quality monitoring and testing. The Metallurgical Microscope assists in the analysis of grain size and structure, phase structure and its distribution, as well as a probe for sub-surface defects while Fractography is used to check internal soundness of rods.

The company practices Total Quality Management and believes that it is every team member’s responsibility to ensure that standard of quality is upheld throughout the entire production cycle.
