Thermoforming
or High Pressure Forming (HPF)
Shaping the printed film is a key stage in producing three-dimensional decorated plastics components using Makrofol and Bayfol films for Film Insert Molding (FIM). In particular, there are two processes - available to the processor - Thermoforming and High Pressure Forming (HPF). The latter method was developed by Bayer MaterialScience and involves the film being formed below the softening temperature using compressed air at a pressure of 20 to 300 bars.
If the printed symbols need to be positioned with high accuracy, the HPF process is at an advantage since distortion is constant and can be compensated by distortion printing. If matt and velvet films are being processed, HPF is preferable too as the texture damage is minimized through reduced heat compared with standard thermoforming.
Thermoforming allows a greater degree of stretching required for deeper draws. It is therefore particularly attractive for large-format components, where decorative features do not need to be positioned with pinpoint accuracy.
Bayfol® films are especially suited for HPF since the film is especially suited for forming at lower temperatures.
