    • The present invention relates to a method of manufacturing a formed article comprising forming an upper surface of a forming material comprised of a thermosoftening substance into a desired shape by positioning the forming material on a forming surface of a mold and heating the forming material to a temperature permitting deformation to bring an entire surface of a lower surface of the forming material into tight contact with the forming surface. The positioning of the forming material is conducted by supporting the forming material with a support member so that at least a portion of a lower surface rim portion of the forming material is in tight contact with the forming surface and a center portion of the lower surface of the forming material is separated from the forming surface, and the support with the support member is conducted so that a lower portion of a lateral surface of the forming material is separated from the support member and at least a portion of an upper edge portion of the lateral surface of the forming material is supported by the support member. According to the present invention, a formed article with a desired shape can be manufactured with high precision by hot sag forming method.
    • 本发明涉及一种制造成形制品的方法,包括通过将成形材料定位在模具的成形表面上并将成形材料加热至一定温度,从而将由热软化物质构成的成形材料的上表面形成所需形状 允许变形使成形材料的下表面的整个表面与成形表面紧密接触。 成形材料的定位通过用支撑构件支撑成形材料来进行,使得成形材料的下表面边缘部分的至少一部分与成形表面紧密接触,并且下表面的中心部分 成形材料与成形表面分离,并且支撑件与支撑构件被导通,使得成形材料的侧表面的下部与支撑构件分离,并且至少部分上部边缘部分 成形材料的侧表面由支撑构件支撑。 根据本发明,可以通过热凹陷形成方法以高精度制造具有期望形状的成型制品。
