Processes
Spherodise Annealing
For the better formability of material during cold forging we have developed in-house spherodized annealing process which is programmable & automatically controlled by controller.
Wire Draw
To achieve the required size of wire for cold forging we have developed the in-house wire draw process along with the set-up of acid pickling & coil Phosphating.
Cold Forging
We have a high speed & extra long bolt formers with multi stations to produce special fasteners like Hub Bolts, CR Bolts, flange bolt, Round head square neck bolt, etc.
Also We have a capability to design the carbide toolings for standard fasteners as well as special fasteners & robust tracebility system for the same.
Machining
Modernized machine operation set-up is well equipped with CNC & VMC turning centres which ensure high accuracy & precision.
And for conventional operations like grooving, slotting, drilling & Pointing we have a special purpose machines as well as lathes, drills, slotting machines, milling machines etc...
Centre Less Grinding
To Control the Ra value in special fasteners like Connecting rod bolt we have a line-up of centre less grinding machines having accuracy within 10 μ.
Thread Rolling
We have well equipped in-house thread rolling shop having automatic tangential thread rolling machines equipped with an auto loading & unloading conveyor system.
We also have a line-up of circular thread rolling machines for the special & extra long threaded fasteners having thread rolling after heat treatment.
Special Processes
Heat Treatment
Regarding part performance, reliability & durability we have developed in-house heat treatment facility. which covers two continuous mesh belt heat treatment furnace having accuracy 2-3 HRC.
For the better process control we have also installed the "SCADA" (Supervisory control and data acquisition ) in both of the set-ups.
Surface Treatment
To provide the Corrosion resistance during part application into different weather condition as well as to fulfill the asthetic aspects of the customers we have in-house platting as well as phosphating plant.
Platting process plant is having fully automatic & semi automatic setup as well.
Hydrogen De-embrittlement
Hydrogen embrittlement is a phenomenon that causes loss of ductility into high strength material having platting as a surface treatment, thus making it brittle.
To remove the hydrogen from the surface of the fasteners we are doing hydrogen de-embrittlement process immediate after platting OR Phosphating with continuous conveyor type backing furnace.
