Polystyrene injection molding temperature
WebThe cooling time tla required until the average temperature of the molded product becomes 50°C is calculated using the following equation. t la = s 2 / (π 2 •α) ln (8 / π2• (θr - θm) / (θe - θm)), where, tla is the cooling time (sec) related to the average temperature of the wall thickness; s is the wall thickness 1.5 (mm) of the ...
