If the engine is considered to be the heart of any automotive part, the efficiency and health of the engine
depend on the functioning of the various engine components such as cylinder sleeve, cylinders,
crankshafts and flywheel. The engine components are known to outlive the engine; for which reason,
planning, designing, development and manufacture all play a very important role in defining engine
components. Cooper Corporation is a name that everybody is familiar with. As a manufacturing company
of over five decades, the company has been re-defining India’s manufacturing story by developing a
manufacturing portfolio consisting of generators, engines, engine components consisting of varied
capacity and ranges. Product Design and development, manufacture and distribution of engine and
engine components for markets within and outside India is their area of core competence.
Cooper Corporation is a market outperformer as a Cylinder Sleeve manufacturer supplying about
175,000 liners to Jaguar and to engine manufacturers like Cummins. Since the Cylinder sleeves form
the basis of engines, the company designs and manufactures sleeves depending on the engine
specifications; be it, by changing alloys, metallurgy, a thickness of material and accuracy of machining.
Since the cylinder sleeves are used for a wide range of applications such as in compressors, generators,
agricultural applications and other types of equipments, they are made available in a broad range of
bore diameter, length and thickness. So as a Cylinder sleeve manufacturer, Cooper ensures that
the sleeves are tailor-made keeping in mind the purpose, application and use and as per the exact
specifications that are given by its customers.
Quality control over engine components
Today, the company exports cylinder sleeves and other engine components such as crankshafts or
flywheels to equipment manufacturers and engine manufacturers across Africa, China, Europe and
Sri Lanka and has of late expanded its horizon to the US markets as well. From agricultural pumps to
high-capacity engines with capacity up to 1MW, all of them are manufactured at their own foundry in
Satara. Since most of the engine components used for their engines or for the use of OEMs are
manufactured indigenously by Cooper Corporation, quality control, standardization of products are
possible at every stage. For example: In order to achieve optimal levels of resistance even for
high-performance engines, crankshaft manufacturers ensure that the designing, production process
etc., is given a lot of consideration. The material used is made of high-quality ductile iron to suit the
various industrial applications. The functioning and structure of various modules of the crankshafts
such as the crankpins, crank arms or webs, supporting bearings etc., are micro-monitored to support
the large load cycles that the crankshafts operate on. To ensure standardization as per international
levels, Crankshaft manufacturers conduct stress test and strain analysis in accordance with the
load applied on the crankshafts.
The flywheels being the vital components of any automotive engine function as points of power supply
from motor to machine by storing rotational energy during the moment of inertia. So when the engine
faces loss of momentum, the stored energy is used up by converting into heat energy in the brakes.
While the material used for the manufacture of a flywheel depends on the application and industry of
use, cast iron, mild steel, composite material like carbon fibre and cast iron followed by a composite
material made by marging steel and E-glass fibre are used in the manufacture of flywheels. Since the
flywheels vary in diameter, weight and the quality of substance used, the design, manufacturing
process and marketing of flywheels to the right target audience plays an important role.
As one of the key manufacturer of engine components, Cooper Corporation has established itself as
a global player in the field of manufacturing be it generators, engines or engine components.
Today, if the generator sales have a critical user base, the engine component segment attributes to a
major chunk of company’s revenues. The company’s rapid expansion and capacity enhancement is
the testimony to high skilled labour, qualified personnel, technological advancement and above all
commitment to quality and in par with international standards.
