PrecisionDesign
and construction concepts used in plastics injection moulding  machines
widely  differ.


Clamping
unit - Direct hydraulic clamp. Hydro-mechanical clamp. (toggle clamp and
other variants).

Injection unit Twin cylinder, in line injection cylinder.


Hydraulics Digital, Analog (proportional).


The
proponents of each concept spoke out its favour with missionary fervour to
win followers. Concepts did not stay as concepts, they became faith.


In the
early days of development, each design approach had its own advantages. With
the advancement in hydraulic and microprocessor technologies the margin of
difference in advantages reduced, boundaries vanished. Proponents mellowed
down.



Manufacturers of machinery left it to the customer to choose. Customer
became the ultimate arbiter.



However, all through these developments, there was one concept uniformly
accepted by all ad not contradicted by any: the fact that moulding a
quality component within a narrow band of deviation i.e. to a consistent
high precision requires closed loop control of
injection function.

The
dynamism of the market comes from the change, and, the people who embrace
that change will be very successful.





Globalization has made the world a single marketplace, and, intensified the
competition. Performance pressure- economic as well as social -have
compelled all of us to accept this change and make best out of the opportunities
offered. In this changing scenario  matter of immediate relevance to us is
the fast spreading trend in the industry - global sourcing, and, produce
where the market is.

It is now in vogue amongst OEMs to move the mould to different global
manufacturing locations and produce parts  for the local market needs, while
guarding the product quality fit to the brand image.

Here the advancement in technologies comes to our help. The
success of moulding process depends on the controllability and repeatability
of injection process to avoid drift of parameters. Machines clones make it
possible to produce identical quality components with least experimentation.
Function closed loop control clones the Injection  Moulding Machines and
help to produce consistent quality mouldings every time, at every location.
