I na pewno nie należy wstydzić się przed autorem tekstu, że nie rozumiesz, co napisał.

Mogę tylko powtórzyć: pytaj autora opisu, niech na rysunku technicznym zaznaczy, o co mu chodzi. To jest opis techniczny. Nie ma miejsca na zgadywanie.

Given the context - resin transfer molding - I believe this might be the lightweight upper mold form. Consider:
LIGHT RTM PROCESS (LRTM)
The Lower Cost Alternative Takes the Lead in the Closed Molding Industry

The LRTM process is founded on what would be considered minimal tooling structure as compared to the traditional RTM or other closed molding process such as SMC or BMC. The tooling structure needed for the LRTM process is similar to that of the open molding process since there is minimal internal cavity pressure. The typical LRTM mold has one rigid half normally for the “A surface” (typically the female cavity) of the mold, with then a lite weight “see through” semi flexible upper mold half. Each mold half is made from a thermoset polyester or vinyl ester tooling gel-coat surface having a fiberglass reinforced thermoset polymer laminate backing that is then normally supported by steel box tubing to retain the tooling shape and provide an ergonomic orientation.

How one gets from lightweight counterform to the lighthouse may remain a mystery.

The question refers to a specification of injection moulds (CNC, resin, infusion, etc.) and models. The original was written by a Frenchman.

The word "lighthouse" must be a translation of some technical French word, hence the need to decipher it in this forum.

Bonjour, vous posez une question sur un forum anglais-français, il serait donc utile de republier la question en formulant la demande en anglais ou en français afin que nous puissions mieux comprendre.
