1) Production Process
Die Design & Fabrication :
The Design & Fabrication of all type of dies are done through exporting the 3D Model into our Die machining centre.
The crankshafts are forged in our 16000 T hammer / 4000 T Press as per requirement & customer specification.
Heat Treatment :
The crankshafts undergo a heat treatment process (H & T) & 100% Crack testing (Magnaflux) before we initiate machining of the same.
Material composition :
The material composition & properties are perfectly checked prior to machining in our R&D Laboratory & testing centre.
Rough machining :
Initially Facing & Centering, Turning & Milling & Oil Hole Drilling is carried out on the CNC Machines in the Rough Machining Unit.
Finish Machining :
The Finish Machining Unit consists of CNC grinding, dynamic balancing, post grinding operations, superfinishing & Accessory
Product and Assembly.
Quality Control :
The R&D Laboratory & Testing Centre consisting of metallurgical testing, Crack Testing, Fatigue/durability testing, Dimensional
testing, etc ensures that every crankshaft leaving our shop floor is 100% quality checked.
2) Concurrent Engineering
Customer Drawing :
Crankshafts of any applications can be made according to drawing or sample. Through these customer specifications we receive the relevant
data required for development.
CAD/3D Model :
The crankshaft drawings & specifications are developed in our CAD or 3D software.
Development Of Processes :
The company has gained expertise in manufacturing of crankshafts for more than 25 years in respect to process of material selection,
heat treatment, surface treatment,etc.
Testing of Material :
Material testing is done in our R&D & Metallurgical laboratory. The Use of materials is decided depending upon the chemical composition
as per engine running type or if specified in Customer drawing.
Development of Prototype :
We have a prototype division where entire process of manufacturing is done on a parallel & flexible line without affecting the series
a) Forging: The crankshafts are forged in our 16000 T hammers & up to a length of 2.5 metres. The crankshafts undergo a heat treatment
process (H & T) & 100% Crack testing (Magnaflux) before we initiate machining of the same.
b) Machining: All machining such as Turning, drilling, milling, threading, etc are done on our automated CNC machines.
c) Dynamic Balancing & Final Assembly: The crankshafts are dynamically balanced & finally Counterweights & gears are installed if required. Then the crankshafts
are ready to install on on the engine
Crankshaft Testing :
The company has an in-house testing centre & R&D laboratory where crankshafts are subject to various tests & the tests are then
collected to understand the future performance of the crankshafts
Preparation of Drawings/Layouts :
As the conclusion of our process of Concurrent Engineering, there is a complete documented solution in terms of drawings/layouts
for the production process
