3.1 Thermoforming
The thermoforming technique uses semi-finished materials such as rigid thermoplastic sheets to transform them into three-dimensional objects with a wall thickness close to the thickness of the starting material.
This is a secondary transformation process, in which the plates or sheets are softened by heating before being shaped by application to a simple geometric mold.
The thermoforming process is divided into five stages:
a plastic plate is placed in a frame which holds it above the mould;
the plate is heated to the temperature required for forming;
the softened plate and the mould are brought into contact...
