Abstract
The invention relates to a workpiece having a shape produced by thermoforming from at least one sheet (3) of plastic material, such as polycarbonate, and at least one applied element (6, 8; 7, 9) that is applied to the at least one sheet and secured there, characterised in that the securing of the at least one applied element to the at least one sheet takes place at least partially by means of crimping.
Claims14
A part with a shape produced by thermoforming from at least one sheet (3) of plastic material, for example polycarbonate, and at least one detachable part (6, 8;
- 7, 9) being detachable from the at least one sheet being rigidly connected to it, characterised in that the rigid connection of the at least one detachable part to the at least one sheet is achieved at least in part by crimping.
A manufacturing process for a part comprising at least one sheet of plastic material, in particular rigid, for example polycarbonate, and at least one detachable part, which consists of stages in which:
- a mould is produced having an external surface corresponding to the shape of the desired final part;
- at least one detachable part which it is desired to connect rigidly to the sheet is positioned on the external surface, for preference on a flat part, this positioning being such at least one part of the detachable part is at a distance from the external surface of the mould;
- a sheet of plastic material, for example polycarbonate, heated to a temperature enabling it to be thermoformed is placed in front of the external surface of the mould;
- the external surface of the mould and the heated sheet are brought into contact to give the sheet its final shape, the sheet, when placed in contact, is introduced between the part of the detachable part at a distance from the external surface of the mould and the external surface of the mould to achieve crimping of the detachable part to the sheet after it has returned to a temperature lower than the bending temperature under load of the plastic material of the sheet, in particular to ambient temperature.
