Abstract
(EN)
The present invention provides a surface cover-equipped component production method that can reduce costs. The invention is a production method for a surface cover-equipped component 6 including: a base body 50 having a front surface 50f, a back surface 50b at the back of the front surface 50f, and a side surface 50s connecting the front surface 50f to the back surface 50b; and a surface cover body 55 continuously covering the front surface 50f, the side surface 50s, and the back surface 50b of the base body 50. The production method for the surface cover-equipped component 6 comprises: dividing a chamber 16, the internal pressure of which is changeable, into a first sub-chamber section 17 and a second sub-chamber section 18, via a deformable partitioning member 4; placing, in the interior of the first sub-chamber section 17, an intermediate body 5 having the base body 50 and the surface cover body 55 laid over the front surface 50f of the base body 50, while orienting the surface cover body 55 toward the second sub-chamber section 18; and reducing the pressure in the interior of the first sub-chamber section 17 while raising the pressure in the interior of the second sub-chamber section 18, thereby causing the partitioning member 4 to deform and press the intermediate body 5, shaping the surface cover body 55 situated between the partitioning member 4 and the base body 50 in such a manner as to follow the side surface 50s and a portion of the back surface 50b, of the base body 50.

La présente invention concerne un procédé de production d'un composant équipé d'un couvercle de surface qui permet de réduire les coûts. L'invention concerne un procédé de production d'un composant (6) équipé d'un couvercle de surface comprenant : un corps de base (50) ayant une surface avant (50f), une surface arrière (50b) à l'arrière de la surface avant (50f) et une surface latérale (50s) reliant la surface avant (50f) à la surface arrière (50b) ; et un corps de couvercle de surface (55) recouvrant en continu la surface avant (50f), la surface latérale (50s) et la surface arrière (50b) du corps de base (50). Le procédé de production du composant (6) équipé d'un couvercle de surface comprend : la division d'une chambre (16), dont la pression interne est modifiable, en une première section de chambre secondaire (17) et une seconde section de chambre secondaire (18), par l'intermédiaire d'un élément de partitionnement déformable (4) ; le placement, dans l'intérieur de la première section de chambre secondaire (17), d'un corps intermédiaire (5) ayant le corps de base (50) et le corps de couvercle de surface (55) disposé sur la surface avant (50f) du corps de base (50), tout en orientant le corps de couvercle de surface (55) vers la seconde section de chambre secondaire (18) ; et la réduction de la pression à l'intérieur de la première section de chambre secondaire (17) tout en augmentant la pression à l'intérieur de la seconde section de chambre secondaire (18), amenant ainsi l'élément de partitionnement (4) à se déformer et à presser le corps intermédiaire (5), mettant en forme le corps de couvercle de surface (55) situé entre l'élément de partitionnement (4) et le corps de base (50) de manière à suivre la surface latérale (50s) et une partie de la surface arrière (50b), du corps de base (50).
