Manufacturing companies provide full solutions
for the vacuum casting of metals and plastic with
a wide range of machinery. The process of vacuum
casting uses rubber silicon tools. It has been
used for bridging gap between models that are
three dimensionally printed and production method
that is injection moulding, typically.

Turnkey Solutions
The companies present Vacuum casting services
whereby they not only make moulds of high quality
but offer full line finishing services inclusive
of pad printing, sanding and more. They help in
creating parts for display models that are
showroom quality crowd funding campaigns and
engineering-test sample. The process vacuum
casting using polyurethane is a process to make
prototypes of high quality or parts in low
volumes from silicone moulds that are inexpensive.

Works
Tools are produced from three dimensional printed
master with the help of SLA, so that no highly
priced hard tooling is needed. The Master gets
completed as per the requirement of the designer,
for instance it can either be for matte surface
or gloss surface finish. After the production of
three dimensional master it is vital that mould
is prepared. Firstly, the split line gets taped
around a moulds central point. Secondly, desired
material gets poured inside besides there is
removal of access of air from the tools, small
vents and central feed.

Use of Casting Process
The process of vacuum casting would be used when
prototype part has been required, normally. It is
made using the process of injection moulding but
can also be used for production at low volume.
The tools of vacuum cast are made of silicone RTV
rubber. This process of casting uses parts that
have fine level details and great quality of
surface.

Advantages
The advantages of this process are many and some
of them include lower costs for mould and
development of product that enables products in
being realized with in shorter time of lead. The
other advantages include manufacturing of moulds
within the nick of time and many kinds of
polyurethane resins that are available for the
process of casting, inclusive of over moulding.

Things to Remember
Designers can improved their computer aided files
for making the prototype of vacuum cast,
successful. However things that must be kept in
mind include, keeping the same thickness walls
and undercuts to minimum. This is because large
undercuts create issues on removal from moulds
