Abstract

Det er beskrevet en fremgangsmåte for fremstilling av en støpt gjenstand som innbefatter innføring av en herdbar epoksyharpikssammensetning i en form som befinner seg ved en temperatur som er høy nok til å initiere herding av harpiksen og det tilføres ytter- ligere harpiks under trykk for å kompensere for krympning av sammensetningen, epoksyharpiksen inne- holder grove dekorative partikler, hvorved epoksyhar- piksen innføres i formen gjennom en åpning (6) som har en lengde (2) som er 30 til 100% av den dimensjonen av det formgitte produktet som befinner seg nær åpningen og en bredde (10) som er minst to ganger den maksimale størrelsen av de dekorative partiklene.
