Abstract

Oppfinnelsen vedrører en fremgangsmåte for fremstilling av massive, hule eller åpne profiler, særlig profiler som har skarpe hjømer og er fremstilt av polystyren. Fremgangsmåten innbefatter de følgende trinn: dosering av polymerer som innbefatter polystyren og, eventuelt, andre additiver og tilsetninger, plastifisering av komponentene i en ekstruder for oppnåelse av en homogen blanding, injisering av en tiykksatt gass via en injiseringsåpning, bearbeidelse av denne homogene blanding og gass og tiykksetting av dem helt til det er oppnådd en fullstendig løsning av gassen slik at det oppnås en enfaseblanding, progressiv kjøling av enfaseblandingen med bibehold av det trykk som er nødvendig for løsingen av gassen, overføring av enfaseblandingen til et formeverktøy for dannelse av et skum, overføring av det dannede skum til et kalibreringssystem med en eventuell temperaturstyring, og motortrekking av det kalibrerte skum.
