摘要： In a machine for moulding of composite plastic material, in particular of foamed polystyrene coupled with rigid polystyrene sheet, the rigid material (2) is preformed at a performing station, with the preformed portion being simultaneously separated from the starting material, and the preformed shaped portion is transferred from the preforming station to a moulding station, in which the foamed material is moulded by sintering and pulsed steam action on the preformed rigid material. The resulting piece is brought back to the preforming station (1) and a further portion of rigid material (2) is preformed on the foamed material, and this portion is then thermoset inside the moulding mould (3) on the foamed material, thus generating an article with two opposite surfaces made of a rigid material, between which the foamed material is sandwiched.

摘要： An injection molding method for forming molded products of foamed plastics, in which molten resin mixed with foaming agent which begins foaming after being kept at a required temperature for a required time is injected into a metal mold wherein the foaming agent mixed together with the molten resin is solidified in a body in the metal mold under such conditions that the portion of the foaming agent molten resin mixture which is in contact with the inner surface of the metal mold is accordingly cooled rapidly such as to substantially prevent foaming thereof, so that the appearance of the molded product is finished neatly, while the foaming agent/molten resin mixture in the inner part of the mold is cooled gradually so that the temperature thereof is not rapidly decreased, under conditions wherein the foaming agent begins foaming and the inner portion of the molten resin is therefore expanded from inside owing to the foaming pressure, which expansion substantially prevents the occurrence of depressions in the surface of the molded product which might otherwise be caused due to shrinkage upon cooling of the resin.

摘要： A method for testing foam formulations for the quantitative measure of the effects of formulation and/or process variable changes on some kinds of surface problems of a molded part caused by different degrees of imperfection or voiding underneath the part surface. The molded part can be single component or composite, solid or foamed. One example of the surface problem is the so-called "measles or cellulite" problem observed on the vinyl surface of a vinyl/foam composite due to the voids or rattiness within the foam. To accomplish this result, the mold has various sized, spaced apart, aligned openings formed in each of the front and rear walls of the mold, but with the centers thereof at different elevations in the respective front and rear walls. Removable rods inserted through the aligned mold wall openings produce longitudinal openings through the part which is molded around the rods, permitting the effect thereof on the surface of the molded part to be evaluated.

摘要： A method and apparatus for forming large fiber-reinforced foamed plastic panels is disclosed. The panels are produced by a process comprising filling a flat mold with freshly mixed foam plastic precursors, including fibrous material for reinforcement of the panels, closing the mold until the plastic precursors have foamed and set, then opening the mold and removing the finished panel. The apparatus comprises a platen mounted for traversing under the dispensing outlet of a mixing device, whereby the platen is filled with foamed plastic precursors, and a press into which the platen travels before the mixture has begun to mold. The press is provided with a novel mechanism for closing the mold by placing a cover on top of the platen before the plastic begins to foam. The same mechanism is adapted to open the mold by lifting the platen cover. Thereafter, the platen is moved in a reverse of its entry movement, returning to its starting position for removal of the finished panel. The mechanism for opening and closing the mold is operated by hydraulic operators under the supervision of a sequencing controller which provides a tilting movement during operation, providing for expelling of air during closing of the mold and breaking the surface tension between the platen cover and the finished panel by first raising or peeling one corner of the platen so as not to lift the panel out of the mold.
