Method of manufacturing an article by molding

摘要

A method of manufacturing an article by molding is provided. The method comprises the steps of:
- providing a mould (1) with a mould surface (3) representing a negative image of the article to be manufactured, with openings (7) in the mould surface (3), with flow channels (9) extending from the openings in the mould surface (3) and being connectable to a suction means (11), and with a periphery (5) delimiting the mould surface (3);
- fixing a plastic bag to the periphery (5) of the mould (1);
- inflating the plastic bag to a pressure level above ambient pressure;
- releasing the pressure from the plastic bag (13) while sucking the plastic bag (13) to the mould surface (3) using the suction means (11);
- layering fabrics onto the plastic bag (13) while it is kept sucked to the mould surface (3);
- introducing a resin into the fabrics laid onto the plastic bag (13) and curing the resin.
