For small series production of plastic parts with Injection Moulded finish.
Vacuum Casting (VC) is a manufacturing technique used for low volume production of aesthetic and functional parts. Using PU-based materials and silicone molds, Vacuum Casting is known for its fast production of good quality engineering prototypes for end-use applications.
Data That matters
Vacuum Casting is a relatively slower process than 3D printing/ CNC Machining. Average lead time for delivery varies from 7-21 business days.
Minimum wall thickness
To ensure that the mold is filled properly, a wall thickness of at least 1 mm is recommended. For best results, we recommend a wall thickness of at least 1.5 mm.
No. of moulds fabricated out of each pattern can vary from 1-3 nos. For better accuracy, we follow 1 pattern – 1 mould rule. Each mould is capable of producing 15-25 components (depending on the part geometry) before wearing out, eventually.
Since VC is a fairly skilled job, controlling tight tolerances is a bit tricky. We have observed that VC parts usually display accuracies in the range of ± 0.3% (with lower limit on ± 0.3 mm on dimensions smaller than 100 mm). Critical features can later be machined / finished manually to achieve tolerance of ± 0.2 mm or less.
Maximum Part Dimensions
The maximum part size that we can manufacture in VC is 600 x 600 x 600 mm.
