CNC forms for vacuum forming
- [Narrator] As previously discussed, CNC is a versatile manufacturing method. It can make extremely precise final parts and is a method used to create most factory plastic forming dies, out of metal. Another capability of CNC is making volumetric, one-sided forms for heat-forming sheet plastic. Vacuum forming is a process, in which flat, extruded sheet plastic is shaped over a master form, with heat and suction. The plastic used in this process can vary, in thickness and texture, but calls for thermoplastic sheet, as it may need to be heated and formed multiple times. There are a few steps to vacuum forming. First, the sheet is clamped into a sturdy frame, to keep it square, and is then heated with coils, by an oven, until it reaches a right temperature and pliability. Once the sheet has reached the specified softness and sag, it will be immediately pulled over the form, capturing an impression of the detail and allowed to cool. After the plastic has cooled enough, to retain the…
