    • The invention relates to a method of manufacturing a sandwich panel (10). Such a sandwich panel consists of a foamed core layer (12) and at least one thermoplastic cover layer (14). The sandwich panel is made by in situ foaming. In a first assembling step a core web, comprising at least one sheet of a thermoplastic material (12) containing an amount of a suitable physical blowing agent is positioned between two cover layers (14). The assembly of core web and cover layers is arranged between two press plates. Due to heat and pressure applied in a subsequent foaming step, foaming of the core web and effective bonding thereof to the cover layers is achieved. Subsequently the foamed assembly is allowed to cool down. Remaining physical blowing agent is removed during a subsequent drying step at elevated temperature while the outflow of physical blowing agent via the peripheral edges of the panel (10) is restricted, e.g. by taping (24) or clamping by clamps (16, 20).
    • 本发明涉及一种制造夹芯板(10)的方法。 这种夹芯板由泡沫芯层(12)和至少一个热塑性覆盖层(14)组成。 夹心板由原位发泡制成。 在第一组装步骤中,将包含至少一片含有一定量物理发泡剂的热塑性材料片材的芯片定位在两个覆盖层(14)之间。 芯片和覆盖层的组合布置在两个压板之间。 由于在随后的发泡步骤中施加的热和压力,实现了芯幅的发泡和其与覆盖层的有效结合。 随后使发泡组件冷却。 在随后的高温温度下的干燥步骤中除去剩余的物理发泡剂,同时物理发泡剂通过面板(10)的周边边缘的流出受到限制。 (24)或通过夹具(16,20)夹紧。
