Auto Gauging

All automated lines are equipped with the facility of auto gauging the components and giving feedback to the machine for corrective action in case the part doesn’t conform to the prescribed specifications. The robot picks the element from the machine or intermediate station and puts it on the gauge, the gauge inspects it with the electronic probes & plc-based system for its dimensions. Having the auto gauge in the line has increased the quality and the consistency in the component dimensions, which helps avoid manual interventions, reduces manpower dependency and provides maximum output. The component which doesn’t conform to the specifications is pulled out of the system automatically. This is an entirely unmanned operation.

Robotic Lines

All the lines are automated with robots or gantries where the complete pick & place is done with the robot. The entire line is handled with the robots from the input component to the completely finished component & extended to packing. All the robots are integrated with machines and equipment in the line with the input & output signals through PLC. The robots are from Gudel, Fanuc, Kuka, ABB and the gantries are from Gudel & Felsomat. Also, the Kuka robots are used in foundry equipment to do the work of pick & place of the casting. Key benefits of robots include higher output with reduced manpower & consistency.


The cylinder liner is the most important part of the engine & the inner diameter of the cylinder liner is the most critical parameter of the cylinder liner. The inner diameter surface of the liners is developed with the super finishing operation called honing. In honing, the surface is created with cross hatch, valleys, picks where the actual oil retention is done which is most important for engine performance. The plateau honing is established for all cylinder liners to get the desired bearing ratio. This operation is performed on CNC Nagel honing machine in three steps rough, base & plateau. All CNC honing machines are having the facility of the auto sizing in which the machine stops when the size of the component is as per the specification.

Tool Room

Own tool room facility where all type of the jigs, fixtures, dies are designed & manufactured in-house. Tool room is well equipped with the machining centers, grinding machines, milling machine, drilling machines, turning machines, etc. Also, the required inspections facilities are provided in tool room. Staff & workmen in the tool room are well-skilled, trained & have exposure and expertise to make the tooling. CAD/CAM Unigraphics Nx-10.3 software is being used for design & manufacturing of tooling, dies, patterns, cores box, etc.

Laser Hardening

For high performance engines, the cylinder liner inside the diameter is fortified with the laser hardening process. The inside diameter of cylinder liners is hardened to 50 ~55 HRC & 0.5~3.0mm depth by using laser. Equipment is fully automated & controlled by PLC.

Heat Treatment

Heat treatment consists stress reliving, hardening & quenching, tempering & annealing, etc. We perform relieving on all our components. It is carried out for the component to release residual stresses in castings to improve machinability, dimensional stability and increase the life of the component, without change in mechanical properties. This is being done by using the special stress relieving auto controlled furnaces. We have 8 such furnaces with total capacity of 48mts / day.
