Vacuum casting is ideal for producing small quantities of parts, especially if aesthetics are important. The master part, typically produced by Stereolithography or CNC machining is dressed and textured as required before establishing parting planes, feeds etc. The master is then mounted within a frame and liquid silicone cast around it. After curing the master is cut out to leave a cavity into which a variety of polyurethanes can be cast under vacuum.


The silicone has sufficient flexibility that undercuts can be released by flexing the tool, although deep draws may require additional tooling splits.
Tool life varies with resin cast, but is typically around 20 parts by which time the tool surface has started to harden and the tool flexibility deteriorates. Using multiple masters and producing multi cavity tools can produce greater quantities, although cavity life will remain around 20 parts.
The process is relatively labour intensive and typically requires between 2 and 5 days to produce first off castings. This is on top of the time to manufacture and dress the master part. These times are dependent upon part size as this affects material curing times.
In evaluating vacuum casting, especially if quantities require multiple cavities, it may be worth considering RIM or injection moulding. Alternatively if quantities are low it may prove faster and more cost effective to make multiple laser sintered parts. These alternatives are dependent upon part size, complexity and time available.

Tolerances vary depending on material and supplier, however as a general rule using ± 0.25mm to 100mm and ± 0.25% thereafter will provide a 'safe' estimate. Note these are process tolerances and should be applied on top of any master part tolerance.
Minimum Feature Size: In a similar way to injection moulding, this is determined by the ability to get the polyurethane to 'flow' into small features. As a wall section, 1mm is about the minimum achievable, however if the area is small enough this can be improved upon.


AIRCRAFT MODEL STAR(INTERNATIONAL) CO., LIMITED founded in 2011,at DongGuang GuangDong, 2000 square meters',Specialize in,develop,produce,Foreign trade,rc model,plane model,quad copter UAV plane,precision component metal accessories process etc.

Aircraft model star( international) co., limited from ZXmade team. ZXTECH (HK) CO.,LTD was set up by Doctor Yang (Young) in March, 2005. ZXTECH started rapid tooling manufacturing since it was founded and got involved in rapid CNC prototyping one year later, after another year endeavor, ZXTECH decided to focus on rapid precision engineering for complex prototyping to improve its competitiveness, which has led the Chinese RP field since the second half year of 2007. Now, ZXTECH has combined rapid tooling, rapid prototyping and rapid precision engineering technologies in the rapid manufacturing field, which is unique in China. In September, 2008, a very famous western-owned prototyping company found ZXTECH and made ZXTECH as their key supplier for precision prototyping, metal forming and machined extrusion parts for exports. This has helped ZXTECH greatly in improving their quality standards and management to meet standards, international standard, but with 100% Chinese costing.
