Eta Technology [P] Ltd manufactures a wide range of special purpose machines, electrical upsetting machines, assembly machines and test rigs for auto components. Electrical Upsetting Machines for Engine Valves is used for the manufacture of flanged components from bar stocks [e.G. Engine valves, half shafts].

Features and functions of the Electrical Upsetting Machines for Engine Valves includes -

• The bar is held near one end between two Cu jaws with the end firmly, butting against an anvil.

• The secondary of a resistance transformer is connected to the anvil and jaws.

• The Portion of the bar between the Cu jaws and anvil short circuit the transformer, a heavy short circuit current passes through this section and consequently, heats up this section.

• An upsetting force is applied axially on the job from the other end and the plastic material in the heated section deforms into a bulb shape.

• When the required volume of material is thus gathered in the bulb the operation is stopped, the job is transferred to a forging press and the bulb is forged to the desired shape.
