Modellering van thermo mechanisch gedrag bij kunststofvormgevingsprocessen KU Leuven
In vacuum forming, thermoplastic polymeric sheets are moulded into complex 3D shapes by first heating the sheet above its glass transition temperature to soften the material and then shaping it by applying vacuum. The quality of a vacuum-formed part relates strongly to the final wall thickness distribution. The variations in the wall thickness are caused by non-uniform heating and local differences in thermomechanical properties of the ...
