Vacuum casting or silicone molding technology uses the model which produces by CNC machining or 3D printing method, to make the silicone mold in vacuum. And uses PU material to fill out silicone
mold cavity in vacuum, to form the exact same model as the prototype.
In rapid prototyping industry, Vacuum casting or Silicone molding is a very common method. It is mainly used in making plastic product at low volume.Usually, if prototype with quantity of dozens to
hundreds pieces, Vacuum casting or Silicone molding is the most economic way.Due to its fast turn over, low-cost, Vacuum casting or Silicone molding can greatly reduce the cost of product
development, cycle and risk.
