Abstract

本发明涉及一种用于在热压机(1)中模制生胎(8)的方法,该热压机具有由至少两个机罩部分制成的机罩并且具有容器(7),该容器布置在这些机罩部分中的一个机罩部分中并且包含硫化模具(6),该硫化模具包括模制该生胎的外侧的模制部分,该方法具有以下连续步骤:‑ 将加热囊定位在生胎(8)内部,‑ 将气体引入到该加热囊的内部中,并且将该加热囊中的内部压力设定为0.10巴至0.70巴,‑ 在这些机罩部分(3,4)的若干增量移动中闭合该热压机(1),‑ 其中,第一增量移动涉及闭合这些机罩部分(3,4)以在该机罩的内部形成真空室(13),在该真空室中能够产生真空。在产生真空的同时,该真空室(13)中的压力(PV)与该加热囊内部的压力(PB)之间的压力差(PB)被设定为0.1巴至0.7巴,并且维持至多±0.2巴的偏差。
