摘要： A method for producing a thermo formed part comprises the steps of: closing in a mould a heated sheet (L) made of thermoplastic material in such a manner as to deform the latter, then cooling it inside the mould until complete consolidation is achieved; during cooling, cutting the sheet along at least one edge portion (E) thereof, this cutting operation causing a bending of the edge portion against an abutment surface (1s) in the mould; and removing the upper half-mould from the lower half-mould once the consolidation of the deformed sheet has been attained. During the cooling of the sheet inside the mould, subsequently to the cutting operation a folding operation is performed, this folding operation comprising the steps of: moving the abutment surface away from the edge portion of the sheet, and operating on the edge portion in such a manner as to resume its bending towards a support surface (2s) of the sheet in the mould.
摘要翻译：一种用于制造热成型部件的方法包括以下步骤：在模具中将由热塑性材料制成的加热片材（L）以使其变形的方式封闭，然后在模具内冷却直至完全固化; 在冷却期间，沿其至少一个边缘部分（E）切割片材，该切割操作导致边缘部分抵靠模具中的邻接表面（1s）弯曲; 一旦达到变形片材的固结，就从下半模上取下上半模。在模具内的薄片冷却期间，在切割操作之后，执行折叠操作，该折叠操作包括以下步骤：将邻接表面远离片材的边缘部分移动，并且在边缘部分上操作以恢复其向模具中的片材的支撑表面（2s）弯曲的方式。
