Vacuum casting is mainly used in small-volume product production and rubber prototypes production, which is one of the commonly used processing methods for rapid prototypes.
Steps for making Vacuum Casting prototypes:
Firstly, produce a master prototype by CNC or 3D Printing, put the master prototype into the simple mold.
Secondly, Pour the liquid silicone into the inside, the silicone mold with a sharp blade divided into two parts, remove the masterpiece from the cured silicone mold, empty out the cavity of the silicone mold and the silicone mold is ready.
Finally, Pour the liquid material(e.g. PU, ABS) into the silicone mold, and the liquid material is curved in the mold and reproduces the same product as the master prototype.
