Abstract
Provided is a process for forming a sheet of thermoplastic material into a three-dimensional shape, the process comprising the steps of (i) forming the sheet at a temperature below its glass transition temperature to produce a first formed shape in the sheet, followed by (ii) raising the temperature of the first formed shape () to above its glass transition temperature whilst a male former (), having at least a portion of its profile being substantially the same as that of the first formed shape (), is positioned to substantially align at least a portion of its profile with that of the first formed shape (), thereby restricting the first formed shape from shrinking back towards its original sheet form, followed by (iii) further forming the first formed shape () at a temperature below that of the glass transition temperature, to form a second formed shape (), followed by (iv) raising the temperature of the second formed shape () to above its glass transition temperature whilst a male former (), at least a portion of its profile being substantially the same as that of the second formed shape (), is positioned to substantially align at least a portion of its profile with that of the second formed shape (), thereby restricting the second formed shape () from shrinking back towards its original sheet form.
