A method and apparatus for a continuous compression molding machine. The continuous compression molding machine comprises a tooling die, extending through a heating zone and a cooling zone, a tooling sleeve, and a biasing system. The tooling sleeve corresponds to the tooling die and is for use in forming a thermoplastic composite part from a thermoplastic composite charge when the tooling sleeve with the thermoplastic composite charge is moved with respect to the tooling die through the heating zone and the cooling zone. The biasing system is configured to hold the thermoplastic charge at a first angle within the heating zone and hold the thermoplastic composite charge at a second angle within the cooling zone, as the tooling sleeve moves through the heating zone and the cooling zone with the thermoplastic composite charge. The first angle is different from the second angle.

A compression molding system includes a first extruder to output melted plastic, and a second extruder downstream from the first extruder to mix the melted plastic with wood chips to output a composite material. A transfer valve alternately directs the composite material between inner block molds and outer block molds. Each inner block mold has an inner block press associated therewith to press the composite material into a desired shape of an inner block having an opening on one side. Each outer block mold has an outer block press associated therewith to press the composite material into a desired shape of an outer block having an opening on one side. A press assembly presses one of the inner blocks into the opening in one of the outer blocks to form a double wall block.

A process is capable of producing a high-quality fiber-reinforced plastic with good yield in a short molding cycle time despite being atmospheric pressure molding. The process characterized uses local contact heating to give different temperature conditions to produce a fiber-reinforced plastic by atmospheric pressure molding from a fiber-reinforced material which contains a reinforcing fiber impregnated with a thermosetting resin composition.

A manufacturing device for an optical sheet according to the present invention includes a first belt 34 extending on a first heating roll 31 and a first chill roll 32 and a second belt 44 extending on a second heating roll 41 and a second chill roll 42. The first heating roll 31 presses, from the surface of the second belt 44, a second belt non-contact portion PT2 of the second belt 44 facing the first belt 34 where the second heating roll 41 is not in contact with the second chill roll 42. The second chill roll 42 presses, from the surface of the first belt, a first belt non-contact portion PT1 of the first belt 34 facing the second belt 44 where the first heating roll 31 is not in contact with the first chill roll 32.

The invention relates to an apparatus (1) for laminating a substrate (12) with a thermoplastic film (11), the apparatus (1) comprising the following: —a laminating unit (2) for laminating the substrate (12) with the thermoplastic film (11), —a feed device (4) for the thermoplastic film (11) to the laminating unit (2), wherein the feed device (4) for the thermoplastic film (11) has devices (14) for heating a first side (16) of the film (11) and devices (15) for cooling a second side (17) of the film (11), as well as a number of controllably driven rollers (10) via which the film (11) is guided past the devices (14) for heating and the devices (15) for cooling, wherein a tension of the film (11) can be regulated via the speed of the driven rollers (10).

A method of moulding (10; 20) and apparatus (108; 208; 308) therefor, in which a workpiece (100) is preheated and/or post-cooled before and/or after a moulding process, allowing optimal use of the tool for high precision moulding operations.

The present invention relates to a cooling method and a cooling device of molded resin products which are made from a synthetic resin as a raw material and are ejected from a press molding apparatus. An object of the present invention is to shorten a molding time and ensure product quality. A molded resin product M which is ejected from a die in a still hot state is supplied on plural jigs 30 on a rotational stage 26 in a cooling chamber 24 from an inlet 34. Dry mist F is sprayed from nozzles 60 of spraying units disposed at upper portions of the cooling chamber 24 to the molded resin product M. The dry mist F sprayed from the nozzles 60 to the molded resin product M is vaporized under a heat amount in which the molded resin product M has. Thereby, the heat is removed from the molded resin product M, and the cooled molded resin product M is ejected from the outlet 38 without adhesion of a water droplet. The dry mist is sprayed in a state that the cooling chamber 24 is closed. The molded resin product M during cooling is mounted on the jig 30 for preventing deformation due to gravity.
