This transition occurs because of the change in volume with temperature. Generally, solids shrink as they are cooled.

WebMelt temperature 320-340 degC Mold wall temperature at least 140 degC A medium injection rate is normally preferred. All mold cavities must be effectively vented. Tool temperature of at least 135 degC is recommended for parts to achieve maximum crystallizable potential. WebGlass Transition Temperature (Tg) is the point at which a material alters state – going from a glass-like rigid solid to a more flexible, rubbery compound. Tg is normally measured on a Differential Scanning Calorimeter (DSC) piece of whizzy equipment. The DSC automatically plots a chart which you can calculate the approximate Tg from.
