    • The present invention relates to a method of manufacturing a formed article 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 a lower surface of the forming material into tight contact with the forming surface. As the mold, a mold having, on a forming surface thereof, a plurality of irregularities with a maximum height Rmax ranging from 0.1 to 100 micrometers and an average spacing S between local peaks ranging from 0.01 to 1.00 mm is employed. The present invention further relates to a mold and method of manufacturing the same. According to the present invention, a formed article with a desired shape can be manufactured with high precision and high productivity by hot sag forming method without the occurrence of the fusion between the forming material and the mold.
    • 本发明涉及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到允许的温度来制造形成由热软化物质构成的成形材料的上表面成形为所需形状的成形制品的方法, 变形使成形材料的下表面与成形表面紧密接触。 作为模具,具有在其成形表面上具有最大高度Rmax为0.1至100微米并且在0.01至1.00mm范围内的局部峰之间的平均间隔S的多个凹凸的模具。 本发明还涉及一种模具及其制造方法。 根据本发明,可以通过热下垂形成方法以高精度和高生产率制造具有所需形状的成形品,而不会在成形材料和模具之间发生熔化。

    • The present invention relates to a method of manufacturing a formed article 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 a lower surface of the forming material into tight contact with the forming surface. The forming is conducted while an exposed portion on the forming surface side of the mold upon which the forming material has been positioned is covered with a covering member. The present invention further relates to a covering member and a forming apparatus. According to the present invention, formed articles with a desired shape can be formed with high accuracy by preventing the contamination of upper surface of forming materials by foreign matter during forming.
