    • A molding die includes a die having a mold plane; and gloss control granules composed of 50 to 80 pbw of a shape retention fixation base material such as a thermosetting resin; 30 to 80 pbw of a diffuse reflecting surface formation core material such as a ceramic powder; and 5 to 10 pbw of a roughness enhancement material such as an inorganic fiber, adhered to the mold plane in a spaced-apart manner. The gloss control granules are each independently adhered in the spaced-apart manner to form gloss control projections on the mold plane of the die so that a surface of a molded product molded on the die forms a surface having a small specular reflection or a diffuse reflection, and the gloss control projections having fine, uneven surfaces with recesses and projections are formed on the mold plane at a coating rate of 40 to 80%.
    • 模具包括具有模具平面的模具; 以及由50〜80pbw的形状保持固定基材如热固性树脂构成的光泽控制颗粒; 30至80pbw的漫反射表面形成芯材料如陶瓷粉末; 和5〜10pbw的粗糙度增强材料如无机纤维,以间隔的方式附着在模具平面上。 光泽控制颗粒各自独立地以间隔的方式粘附以在模具的模具平面上形成光泽控制突起,使得模制在模具上的模制产品的表面形成具有小镜面反射或漫反射的表面 ,并且在模具平面上以40〜80%的涂布速度形成具有细小的具有凹凸的凹凸表面的光泽控制突起。
