Proper heat control, and hence, accurate temperature monitoring, is essential for materials such as polypropylene, for which the forming temperature range is very narrow
Thermoforming is the process by which a thermoplastic sheet is made soft and pliable by heating, and biaxially deformed by being forced into a three-dimensional shape. It may take place in the presence or absence of a mold. Heating the thermoplastic sheet is one of the most crucial stages in the thermoforming process. Most thermoforming machines use sandwich-type heaters - panels of infrared heaters above and below the sheet. This type of heating is recommended to give even heat distribution across ...
