VV American International are backed by a well-built infrastructure equipped with avant-garde technology and latest machines. Our manufacturing unit is spread over a wide area with adequate production capacity. Our production capability is rested on the latest machinery that not only enhances the production but also helps us meeting the ever rising demands of clients. Our unit is segregated into different section where various manufacturing process such as annealing, normalizing, stress relieving, hardening, welding and tempering are undertaken.
The presence of the extremely sophisticated machines and the workforce enhance the productivity, which in turn enhances us to lure huge profits. The segregation of the departments and the distribution of work among the skilled employees and labours. Both manual and machine workforce constitutes the infrastructure of a company and has their own particular importance in the organization.
hearing & Heating of Cropped Piece
- Using highly efficient eccentric presses the blank is cut according to the size of double open end spanner to be forged.
- Then the blank is heated up to the exact pre-selected temperature (1000-1200° C) in the pusher furnace before forging it to its form.
Hot Forging & Trimming Process
- The red hot cropped piece is pulled out of the furnace with the help of tongs and kept under lower and upper dies to give it a shape under tons of pressure from the blows of the drop hammer.
- Then the trimming process is carried out to remove the surplus steel.
The Grinding Process
-Using different types of grinding belts of special grain structure the burr on the outer surface of the head & shaft is removed using grinding process.
Broaching Operation to Dimensional Accuracy
- This is an important operation to produce the exact size of the jaws.
- The broaching tool is pressed through the forged jaw opening to produce the exact size in case of open end wrenches and the broaching tool is passed through the ring surface to give it profile in case of Combination & ring Spanner.
Over Drive Broach
- With our constant R & D we have developed the new profile in the ring wrench head.
- In this design the force is applied to the flanks of the bolt heads & not to the corners.
- This type is also suitable even for 50% worn rounded fasteners.
Hardening & Tempering Process
- Hardening & tempering is done in an automatic shaker hearth furnace in which both hardening & tempering temperature are controlled.
- By this process the structure of steel is made finer. The hardness achieved in this way guarantees the high value in the tools use, the great torque can be transferred, and service life of our tools.
The Plating Treatment
- Different kinds of surface protection is given to wrenches by the process of plating treatment.
- Here the tool is first degreased carefully, then nickel plated and finally chromium plated.
