Core Processes Infrastructure Tool Manufacturing & Maintenance

Supreme Grip At Engineering

Having a team of experienced professionals and infrastructure to undertake several processes gives us the benefit of taking over even the most complex lamination projects. Kumar Stamping is known for its customized services and the perfection in every project that it undertakes. Working from the past 38 years has bestowed us with an expert knowledge to provide customized attention to meet individual customer needs.

Core Processes

Stampings Punching

Progressive Stamping
Blanking
Notching

We efficiently cater to lamination requirements of its clients with the help of a number of high speed presses varying from 50 ton to 300 ton with speeds up to 400 SPM for lamination punching. Our fully automatic stamping lines are equipped with auto-skewing & auto stacking controllers , high tech de-coilers, S-type material straightener & geared feeders for running ultra-precise carbide progressive tools

Hysteresis Loss Decrease

Eddy Current Loss Decrease

Carbon Percentage Decrease

Grain Size Increase

Annealing

We have a state-of-art Hi Perming Facility for the decarburization of laminations in order to develop a uniform grain structure for the reduction of Watt Loss of the material so that the efficiency of motors could be enhanced significantly. Precise computer-controlled furnaces ensure proper grain structure growth for lower core loss and improved permeability. The laminations are heat treated in a specific atmosphere having a composition such that the carbon level is lowered to a few thousandths of a percent in order to minimize hysteresis losses. Another advantage is the production of a thin, adherent coating of iron oxide on the lamination, having a low electrical conductance. This effectively insulates the laminations from one another and prevents the flow of eddy currents which would result in large electrical losses..

Rotor Die Casting

We have an extensive in house die casting facility with numerous die casting machines (80T to 200T), both horizontal & vertical, capable of casting rotors of varied sizes. These high-tech machines have short shot cycle and have high quality imported multi-quality tools running on them for increased production.

These precise machines are well complemented by our high-tech furnaces which are very closely monitored to ensure high quality molten metal, which translates to both high conductivity and tight control of porosity.

Infrastructure

The company has invested significant capital in establishing state-of-the-art manufacturing facilities. The location is strategically chosen to be in close proximity to few of the top steel producers and to the inland New-Delhi port.

2 manufacturing facilities
100000 square footage of operation
ISO/TS 16949,
ISO 9001 & ISO 140001 certifications at both facilities
