摘要： PURPOSE:To separate composite material formed by integrally laminating a plurality of materials into each material CONSTITUTION:A rectangular body 12 obtained by cutting a plastic product is formed by laminating a skin layer 14 consisting of different plastic materials, an expanded layer 16 and a base layer 18. Firstly, the rectangular body 12 is beaten by charging it into a hammer mill. Small pieces consisting of the skin layer 14 are separated from small pieces consisting of the expanded layer 16 and the base layer 18. Furthermore, the small pieces consisting of the expanded layer 16 and the base layer 18 are charged into a cutter mill and thereby separated into the small pieces consisting of the expanded layer 16 and the small pieces consisting of the base layer 18. In such a way, since the rectangular body 12 is separated into the small pieces consisting of the respective layers 14, 16, 18 alone, plastic material is recycled by working only the small pieces of necessary material.

摘要： PURPOSE:To heat a mold uniformly in short cycle time by a method in which a slush mold is preheated by hot blast and is heated to prescribed allowable temperature range for molding by radiation heating and then its preheating temperature is controlled. CONSTITUTION:A mold 12 is one step-heated by hot blast in a first heating station 13, and the mold 12 is heated to prescribed preheating temperature in short time at less temperature-difference. The mold 12 is two steps-heated by a burner 42 in a second heating station 14 and is heated to the range T of the allowable temperature for molding in short time at less temperature difference. Then, the preheating temperature of the mold 12 heated by one step heating is set to be higher than the heating temperature T1 at the part where the time axis corresponding to the time t2 wherein radiation heating time(t) of second step is subtracted from the heating time t1 of temperature- raising curve D2 at the shortest heating time in which the mold 12 may be heated to the allowable temperature range for molding by only radiation heating, crosses the temperature-raising curve D2. Accordingly, the mold 12 is one step- heated to the set preheating temperature and then is radiation-heated exactly to the allowable temperature range T for molding through the two steps-heating.

摘要： PROBLEM TO BE SOLVED: To easily produce a windshield member for a vehicle wherein a film having a cured film layer poor in ductility is formed on the surface of a resin substrate without damaging the film. SOLUTION: Windshield glass for a vehicle is produced by integrating films 90, 92 fitted with cured film layers having scratch resistance with a resin 16. In this case, the respective films 92, 90 are fixed to only the upper parts of the respective cavity surfaces of a movable mold main body 60 moving in a horizontal direction and the fixed mold main body 4 opposed to the movable mold main body 60 in such a state that the cured film layers of the films are opposed to the respective cavity surfaces to be suspended. Thereafter, a predetermined amt. of the resin 16 is supplied to the gap between the films 90, 92 and the movable mold main body 60 and the fixed mold main body 44 are clamped to diffuse the resin between both films 90, 92 to fill the gap between the films to integrally bond the resin 16 and both films 90, 92.

摘要： PURPOSE:To efficiently and uniformly heat a molding die by a method wherein a slush molding die is rotated in a heating furnace and a process, in which the molding die is stopped at the predetermined angular position when necessary, and a process, in which the inner surface part and the outer surface part of the slush molding die are heated by the rediant heat emitted from burners, which are arranged so as to direct to a rotating axis center, are provided. CONSTITUTION:A slush molding die 12 is rotated in a heating furnace 42 and, at the same time, stopped for the predetermined periods of time respectively at the predetermined angles R1-R4. For this, the inner surface part 12b and the outer surface part 12a of the slush molding die 12 are successively heated over heating ranges H1-H7 by radiant heat emitted from a plurality of burners 44, which are arranged so as to direct to the axis center O acting as the rotating axis center of the slush molding die 12. Further, by selecting the angles R1-R4 and the heating ranges at the respective angles, the whole molding surface of the slush molding die 12 can be efficiently and uniformly heated in a short period of time. Thus, the efficient whole molding process of skin body is easily realized and the high quality skin body can be obtained.

摘要： PURPOSE:To heat a molding tool up to the desired temperature at all times and molding a molded body of high quality efficiently by computing the heating time of the molding tool from the feed-out temperature of the molding tool from an oven set preliminarily, the temperature of molding tool before feeding and temperature in the heating oven. CONSTITUTION:The feed-out temperature T1 of a molding tool 12 out of a heating oven 30 provided in a first heating station 14 is set based on the characteristics data such a the material quality and shape of the molding tool 12. Then, the temperature T2 of the molding tool 12 before feeding the same into the heating oven 30 is sensed by a radiation thermometer disposed in a first elevator station 24, and also the temperature T3 in the heating oven 30 before the molding tool 12 is fed is sensed by a temperature sensor, and all the temperatures are fed into a control device 29. Through the temperature information on the set feed-out temperature T1 of the molding tool 12, the temperature T3 of the molding tool 12 before feeding in and the temperature T3 in the heating oven 30, the heating time S (second) of the molding tool 12 is computed by the control device 29.
