Patent DE-4324724-A1 (DE)
Title: Feeding system
Inventor: BRUNS ALBERT
IPC: B29C70/54
Filed: 1993-07-23
Abstract: To provide a feeding system, in particular for LCM processes, specifically for RTM processes, in which it is not necessary for resin which has cured in the feed channel to be drilled out, which at the same time is of a simple construction, with which as little waste as possible and which allows the cured material to be removed from the mould without leaving any residues, it is proposed according to the invention to provide that the mouth of the feeding member for the resin mixture to be injected is arranged close to the mould cavity and for the sealing member to be sealed off, at least in the region of the mouth, from the feed channel. Arranging the mouth of the feeding member close to the mould cavity and sealing it off has the effect that no resin can solidify in the feed channel. The invention is essentially based on the idea that there are no moving parts in the resin flow.
