Thermoplastic Composite Having One or More Inner Openings and Method for Moulding Said Composite
20230070857 · 2023-03-09 ·

The present invention relates to a method and mold (100, 110) for forming a thermoplastic composite (1) that has one or more inner openings (0). The present invention further relates to a thermoplastic composite (1) manufactured using such method. Typically, forming of a thermoplastic composite (1) is achieved using a mold (100, 110) comprising a first (100) and second (110) mold part that are moved towards each other for the purpose of forming the thermoplastic composite (1). According to the invention, the mold further comprises a third mold part (120) that is movably arranged around the one or more first mold parts (100). Furthermore, an additional step is used of clamping the outer part in between the second and third mold parts during the mutual movement of the first and second mold parts while allowing the one or more inner parts to move relative to the one or more first mold parts thereby increasing the one or more inner openings, respectively.
