NA-Mfg has wide variety of Eco manufacturing production lines spread across its manufacturing locations. Na-Mfg is one of the pioneer manufacturer and suppliers of closed die hot forgings. All our forging lines are equipped with state of the art billet temperature control mechanisms. NA-Mfg, boasts of wide variety of production lines to cater to satisfy the variety of customer needs. NA-Mfg., has automated high speed production lines and also can take parts with small batch sizes. NA-Mfg, intends to be “One stop shop” for the custom make closed die forging requirements.

Our Eco manufacturing equipped with Mechanical Presses and Drop hammers, where we could able to produce high complex forging profiles ; Weight range from few grams to 100 kgs to the various applications .

Availability and Productivity of the forging equipment are the key to sustainability. Production and Process controls are monitored using state of the art online production monitoring system. Periodic maintenance is carried out on a systematic manner to continuously improve the availability and productivity of the production lines.

Our forging lines are supported by various types of billet cutting equipments , which include saw cutting machines, shearing machines, circular saw machines and high speed shearing machines. Raw material bars of input Round sections and Square sections from 10mm to 180 mm diameter can be cut to accurate lengths and weights as required.

We follow FIFO of material from incoming storage to dispatch. The raw material grades are tracker by using unique color code from the incoming stage. By doing this practice, the parts quality is ensure all the stage. This provides end to end traceability of the components.

We provide the forging parts in various process methods

We make parts from few grams to large precision components in a broad range of grades of

The hot forging manufacturing process is performed at extremely high temperatures (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys). This temperature is necessary in order to avoid strain hardening of the metal during deformation.

The cold forging manufacturing process is performed at room temperature, without any thermal treatment. Cold forging is a manufacturing process where a bar-stock is inserted into a die after phosphating and squeezed with a second closed die. The deformation starts at room temperature and changes the shape and size of the initial part until it has assumed the shape of the die.

Ring rolling is a category of metal rolling, in which a ring of smaller diameter is rolled into a precise ring of larger diameter and a reduced cross-section. This is accomplished by the use of two rollers, one driven and one idle, acting on either side of the ring’s cross-section.

Warm forging is performed with the workpiece heated to a range that is generally above the work hardening temperature and below the temperature at which scale forms. The process fills the niche between the closer tolerance, but sometimes expensive cold forging process and the somewhat lower precision hot forging process. It is being used to produce close tolerance components in steel alloys that were not feasible or impossible by cold forging. It is also being used to produce components very close to the final shape that was formerly made by hot forging with generous finishing allowances. Shafts, gears, and automotive front-wheel drive tulips are currently being warm forged.
