Vacuum casting is suitable for the production of templates due to its lower cost and shorter production time. By using this technique, the original model can be perfectly made. Vacuum casting is suitable for the production of 10 to 100 units of products for mechanical testing or visual testing.
Parts that are identical to the original model can be obtained from the silicon mold, even when working with models in complex geometric shapes.
The application of resin allows your choices for the selection of materials to be as accurate as possible, with options for the degree of hardness, whether it is soft or rigid, and the final appearance (are the parts colors, or transparent like crystal?).
When compared to the aluminum mold or steel mold, production cost can be lowered with the use of silicone mold. Furthermore, economies of scale can be achieved from 10 parts approximately and thus it is cost saving as compared to 3D printing. Lastly, it takes only 7 to 10 days to produce 30 to 50 parts. Clearly, this method is able to satisfy customers with tight turnaround deadlines.
Lifespan of the mold
Silicone molds have a shorter lifespan than injection molding, and can only manufacture limited quantities.
As original model and creation of silicone mold are required, this approach requires a lower cost when compared to 3D printing.
