Apparatus and methods for forming thermoplastic clamshell components are disclosed. In one embodiment, a method includes providing first and second spaced-apart mold members (102,104). Next, first and second half-body portions (118) are formed by a process including forming at least one sheet (106) of formable material between the first and second mold members. The first and second half-body portions are then coupled to form the clamshell component. In alternate embodiments, the coupling of the first and second half-body portions may include forming the flange portions between a pair of heated members, or crimping or welding the flange portions.
L'invention concerne un appareil et des procédés permettant de former des composants thermoplastiques en forme de coque. Dans un mode de réalisation, l'invention concerne un procédé consistant à fournir un premier et un second élément de moule espacés. Puis, une première et une seconde partie de demi-corps sont formées au moyen d'un procédé qui consiste à former au moins une feuille de matériau pouvant être mis en forme entre les premier et second éléments de moule. Les première et seconde parties de demi-corps sont ensuite couplées afin de former le composant en forme de coque. Dans d'autres modes de réalisation, le couplage des première et seconde parties de demi-corps peut consister à former des parties de rebord entre une paire d'éléments chauffés ou à fixer ou souder lesdites parties de rebord.
