This skill comes only after years of experience of doing it every day. Only a regular service provider with expertise in vacuum casting has such specialized personnel. The Moulding Process A perfect piece emerges only when the right equipment’s are used with parameters set according to the polymer mix in use. For instance, PMMA PU has characteristics that differ from PU PC, the latter being chosen for strength and better transparency. Parameters such as time, temperature and pressure are controlled to suit polymer used for moulding.
This results in near-perfect components. Services specializing in vacuum casting are experts in this. Rapid Prototyping The vacuum moulding plastic part may be just one of the many components that form part of a sub-assembly or assembly. Companies cannot afford delays or errors that affect speed to market. Outsourcing short-circuits delays and errors and gives you perfectly moulded components right on schedule. If changes are necessary after trials, then it is trivial to create another master model and mould in no time at all. Cost Saving It proves more expensive to machine each component from scratch or to go in for plastic injection moulding when one needs quantity of only 10 to 100 or so.
Outsourcing saves costs. Quality is far superior and buyer does not have to invest heavily up front in equipment’s or raw materials. He pays only for the mould and parts. If he is likely to order more than the service provider may spread cost of mould over the moulded parts. Then there are other matters such as dimensional tolerances of interlocking parts and removal of flash and vent points as well as keeping undercut to a minimum.
The knowledge part is something one cannot ignore. Service providers specializing in vacuum casting do it day in and day out and are knowledgeable about various types of components and polymer resins that are in use. They can not only give the best recommendation but deliver the right product at the right price. Going down the road, if a company chooses to get injection moulding dies made for mass production then it will benefit from the fine tuning that vacuum casting allows.
