The machines used in CNC plastic machining are milling machines with 3 axes with digital control. They are automated and controlled by a computer that determines the path of the cutter according to the 3D file to be created. In plastic CNC machining, no molds are needed, thus reducing the costs and startup times. The machines can design several identical copies and thus obtain the same quality for all copies of a lot, but few economies of scale are possible. The wide choice of thermoplastics and metals allows parts to be obtained with the desired physical properties.
CNC plastic machining can create very similar parts to series parts. It is often more efficient and faster than other rapid prototyping technologies for the manufacture of a quantity of plastic prototypes between 1 and 10 parts (low volume plastic parts production). We also recommend plastic CNC machining for parts with large sizes (greater than 600 mm).
