Wire Drawing

Omax Auto has vertical integrated manufacturing plant with a production capacity of more than 6000 metric tonnes per year.

All manufacturing processes are carried out in-house with latest technology and most suitable machines with best in class Quality Management System.
• Wire Rod Processing: The process of Wire Rod Processing comes after detailed & thorough inspection of 100% raw material received for chemical compositions and forgeability.
• Wire Drawing: Wire Drawing is carried out to get the required wire size for cold forging the parts depending upon the size of fasteners to be manufactured. Generally, the percent reduction in area is maintained between 7% to 15% so that there is not much resistance for deformation during cold forging wherever high percentage of reduction in area is required during wire drawing. Spheroidized Annealing of wire rod is carried out and its spheroidization value is maintained at greater than 90%. All wires are drawn from wire rod which is spheroidized annealed so that after spheroidized annealing, the wire rod is acid pickled and zinc phosphate which will act as lubricant during a skin passing in the wire drawing machine. This wire is now ready for cold- forging

Annealing Process

• Low Temperature (Stress Relieving) Annealing(500° C to 650° C): It is carried out at 500° C to 650° C for stress relieving the product before next operation. Furnaces used are PIT furnaces and Continuous Tempering Line.
• Vacuum Annealing(800° C): The purpose to carry out this operation is to achieve extra low hardness in vacuum to have decarburization free product working range up to 800° C.
• Spherodized Annealing(700° C): This type of annealing is done to change the lamellar pearlitic structure to Spheroidised structure in order to achieve suitability for Cold forging. Company has a facility 300 Tonnes per month for spherodized annealing.

Forgings

Using the state of art machinary for Cold forging processes & Hot forging process can manufacture a wide range of Industrial Fasteners like Bolts, Studs, Screws, Nuts, Special fasteners etc.

Heat Treatments

• Hardening & Tempering Carburizing
• Nitriding
• Carbonitriding

Secondary operations

Omax Auto Secondary Operation is carried out after the initial first operation Cold and Hot Forged. The operation that is carried out within its premises for the competition of the certain tasks may include some of the operations as mentioned below:-
