As per ISO 9001:2008 certification and its instructions - Some tests, check and inspection -  we go through to pass the product before dispatch are listed as below:

  • All components is made only on the basis of the CADD drawings approved by the customers.
  • Design and drawing development is done by qualified draughtsman
  • Spectrometer to ensure the elements for Material test
  • Induction Melting Furnace  for special graded casting
  • Heat Treatment- Annealing process is done by the approved OEM vendor
  • Induction Hardening Process is done as and when special hardness is instructed by the customer
  • Structure of the material is checked with the help of Microscope
    • *CNC Machining Process for all component machining
    • *Grinding Process is done for OD grinding of all the components
  • Overall run out & concentricity checked by Roundness tester
  • Surface Roughness Tester for Ra Value
  • For internal dimensions, radius and various angles Contour machine is being used
  • Regularly calibrated Micrometres, Vernier Callipers and Bore gauge used for onsite inspection as well as finished components
  • Inside bore checking special air gauge is used
  • Hardness testing machine to check the hardness of the component as per the drawings


Induction Melting

This application refers to Industrial engines and stationary engines especially field of oil and gas, Power Generation. This is the only application in which the engines are stationed at a particular place not moving.


Molted material is poured in centrifugal die/cavity to get the required structure. Pouring process is done in two-stage big ladle pouring and indusial pouring according to product weight. Some additives are also added during pouring to get defect free casting.

Centrifugal Casting

Centrifugal casting process based on the centrifugal force principle. The required shape of the liner is achieved with particular die. We have in-house centrifugal casting die facility. The centrifugal casting process is so essential for liners and sleeves because it provides very dense structure, ultimately increase the life of liner and performance of the engine.

Fine Boring

Boring is the process which gives the final look of inner diameter. We perform boring operation on vertical machining center. Which is fully computerized control machine. We also use special purpose boring machine. Which maintains dimension accuracy, taper, ovality and surface finish.

Outer Diameter CNC Turing

We perform outer diameter of liner on CNC machine, which is computerized control machine, gives high accuracy in dimensional parameters, surface roughness parameters and geometrical parameters. A main benefit of OD CNC Turing is to minimize cycle time, repeatability of quality and consistency product.

Grinding & Stage Inspection

Grinding is the process where super surface finish can be maintained on products. We have two type of grinding process center less grinding and cylindrical grinding. Grinding controls dimensional parameters, surface parameters and geometrical parameters. The process indicators like Cp/Cpk is maintained in this process.

Plato Honing

Honing is the process where required hex pattern can be maintained in finish inner diameter. We use Plato honing process. The main benefits of Plato honing process is to achieve required quality parameters like surface finish Ra, Rt, Rmax, R3z, Rp, MR1, MR2 etc. with process control indicators like Cp/Cpk.,
