Look Before You Mould
As Published in The Financial Express dated 07 Sep 1998
New innovations need large amount
of R&D expenditure and the chances that the end product
may not be up to the specific requirements are high. To do
away with such unwanted expenditure, prototype is made for
the purpose of verifying the form, fir and functional aspects
of the part or an assembly. This enables the designer to be
confident of the design before costly tools are manufactured.
Rapid Prototyping has been introduced
in mid-80's in USA. The parts produced have been used for
developing tools by way of investment casting, epoxy moulding,
spray metals etc. Variety of plastics or metals can be produced
depending upon the process followed e.g. Injection moulding,
press/vacuum forming, sand casting etc.
Various Industries have benefited
from prototypes and this include automotive aerospace, medical
implants & instruments, toys, electrical goods, electrical
switchgears, consumer durables, furniture, packing etc. It
is beneficial as it not only reduces costs but also valuable
time required to develop a new product.
Advances in the field of Computer
Aided Design (CAD) has further added value to this technology
and prototypes are now made at a faster rate. Protosys Technologies
Private Limited is the first commercial organisation offering
such a service in India.
Protosys uses 3D CAD models and
converts it into a prototype sample within few hours. Claims
