摘要： A method of molding an object with a mold having a transfer face includes the steps of filling, separating, re-melting, re-contacting, cooling, and removing. The filling step fills a thermoplastic material, having a temperature greater than a softening temperature of the thermoplastic material, into a cavity space in the mold having a temperature smaller than the softening temperature of the thermoplastic material. The thermoplastic material comes in contact with the transfer face and is cooled. The separating step separates the transfer face from the thermoplastic material to form a heat-insulating layer between the thermoplastic material and transfer face. The re-melting step re-melts the thermoplastic material with heat energy retained inside the thermoplastic material. The re-contacting step re-contacts the re-melted thermoplastic material to the transfer face. The cooling step cools the thermoplastic material to a temperature smaller than the softening temperature of the thermoplastic material. The removing step removes the cooled thermoplastic material from the mold.

摘要： In an aging device used to manufacture a plastic molded product, injecting and aging processes are separated from each other. Namely, a plastic base material is approximately processed in advance in a final shape by injection molding. Thereafter, the plastic base material is inserted into an aging die having plural cavities and attached to a press machine such that the aging die is clamped and opened. Next, the plastic base material is heated and melted until a temperature equal to or higher than a glass transition point so as to generate an internal resin pressure. Next, the plastic base material is gradually cooled to transfer a mirror face thereto. The aging device has a die cooling device having plural heat pipes for cooling the die and has a die heating device having plural heaters for heating the die. The heat pipes and the heaters are arranged in a die plate of the press machine. In this aging device, the aging die can be uniformly and rapidly heated and cooled and a cooling speed of the aging die can be easily controlled.
