   What kind of prototypes are suitable for Vacuum casting processing method to make?

     rubber prototype
     short run production of prototype

    Soft rubber prototype                       short run production prototype
                       soft rubber prototype                                 short run production prototype

The crafts process of low volume production:

Process a prototype by CNC machine or SLA machine, and then produce silicone mold by make use of this
prototype, put the silicone mold to vacuum casting machine and inject different performance PU material,
cooling to another prototype under vacuum. As show below:

Vacuum casting material and application:

Transparent PU- transparent prototype production

different hardness PU—produce all kinds of different hardness rubber prototype

Different performance PU-produce similar to the ABS ,PC,PP performance prototype

Transparent prototype rubber prototype low volume production prototype

remark: Can get a different surface color by adding different pigments during production process.

The advantages and disadvantages of Vacuum casting

The quantity only more than ten can saving cost when adopt vacuum casting process to make prototype,
as it will cost much to open silicone mold and one silicone mold only can copy twenty prototypes at most. If
more than that , due to the deformation of the silicone mold ,the copy prototype will deform and the size of
the prototype will imprecise
