Melting is one of the beginning prominent process of the casting. Due care is taken while melting like charge preparation as per customer material requirements. We have three 500 kg medium frequency induction furnace. Induction melting is mainly used for critical quality material requirements in chemical, physical and micro-structure properties.
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 process based on the centrifugal force principle. The required shape of the liner is achieved with particular die. We have inhouse 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.
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 Turning
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, repeat-ability 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.
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
Final Inspection & Laser Marking
We are following visual step inspection method. Specially designed instrument are develop to act after rough machining & Honing, every piece is thoroughly inspected for casting defects or cracks and for sufficient material thickness, wherever further machining is to be done. After verification has been sent to the packing department.
Laser Marking & Packing
All process passes and finally comes the liner in the packing department.
Where visual inspection and packing are done under supervision.
