Silicone mold vacuum casting was used for production runs or duplicate prototypes and

models. Using the model or pieces produced via CNC,SLA or SLS or sculpture made by clay carving as a master mold to make the silicone rubber mold .This silicon rubber mold is then used via vacuum casting to produce accurate duplicates of the original products .

PS : The Maximum size is 1000mm×800mm×800mm ,and the tolerance can be controlled to 100mm/±0.20mm .

One silicone mold can be used 10 time , but 3~8 times is more better . And the thickness of duplication part is ≦2.5mm .

Step 1: Build mother model	Step 2: Build mold house	Step 3: Pour liquid silicone to build mold	Step 4: Cool down the mold	Step 5: Pour the liquid material to get copies
