Title:
LAMINATION DEVICE, LAMINATION METHOD, AND MOLDED ARTICLE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/188715
Kind Code:
A1
Abstract:
In conventional lamination methods, it was difficult to achieve both removal of air bubbles and followability of embedded material. A lamination method for a lamination device having a first chamber and a second chamber in which an air flow within the chamber is blocked by a thin film member, a substrate material and a film material being transported in a superimposed state between a first press plate and the thin film member, wherein the lamination method includes implementing a pressurization step (S3) for depressurizing the first chamber and pressurizing the second chamber to press the film material against the substrate material using the thin film member, a pressing step (S4, S5) for pressurizing in a direction in which the substrate material and the film material are sandwiched between the first press plate and a second press plate to mold a molded article, and a detachment step (S6) for pressurizing the first chamber and depressurizing the second chamber to detach the thin film member from the molded article.
