COLD FORMING

We manufacture special cold-formed and machined components and work closely with our customers to design products and processes that are best suited for their application. Our extensive cold-forming capabilities range from 6mm to 20mm in diameter, and 15mm to 240 mm in length. The materials we currently work with include carbon steel, alloy steel, stainless steel, aluminum, copper and brass. We have a battery of multi-station cold forming machines from renowned manufacturers such as National, Hatebur, Jyoto and Waterbury Farrell.

MACHINING AND SECONDARY OPERATION

The forging blanks are finish machined on a wide variety of secondary operation machines. Our machine shop has 26 CNC lathes, centreless and cylindrical grinding machines, circular and flat thread rolling machines, Wickman multi-spindle lathes, Drilling and tapping machines and a variety of special-purpose machines that are used for manufacturing high-volume components.

DEDICATED TOOL ROOM

Our in-house dedicated tool room is equipped to manufacture all the critical tools that are required for our manufacturing process. The machinery list includes lathes, cylindrical and surface grinding machines, milling machines, tool and cutter grinding machines and lapping machines. We also have dedicated vendors for critical operations such as spark erosion, CNC wire cut, high-performance surface coating and tool steel heat treatment. We work closely with a number of specialty tool manufacturers to source the best quality carbide tools.

HEAT TREATMENT

Heat treatment is outsourced to our customer-approved suppliers. Hardening and tempering, case hardening, induction hardening, and Nitro carburizing ( salt bath and gaseous ) are some of the heat treatment processes that we currently offer. Our vendors have state-of-the-art furnaces to produce consistent components of the highest quality. Components are periodically tested at NABL-approved laboratories to ensure product quality.

SURFACE TREATMENT

Surface treatment is outsourced to our approved suppliers. Current surface treatment processes include trivalent Zinc, zinc iron , zinc nickel, electroless nickel and other inorganic coatings. SCADA-controlled semi- automatic and fully automatic lines are employed based on the component requirement. Salt spray tests are periodically conducted at NABL-approved laboratories. Plating thickness and other parameters are also periodically recorded using X-ray fluorescence spectroscopy.

QUALITY CONTROL AND INSPECTION

Advanced Product Quality Planning (APQP) is done prior to any new product development. This robust APQP process ensures that the customers’ requirements are thoroughly understood and communicated to all stakeholders. Process capability studies are carried out for critical characteristics or customer-specific requirements. We use standardized practices such as FMEA, MSA, SPC and PPAP to develop products and processes as per our customer’s requirements.
