    Abstract: Disclosed is a method for producing a resin film or a resin sheet comprising a step of cleaning resin pellets and a step of forming the resin film or the resin sheet by using the cleaned resin pellets. The step of cleaning the resin pellets comprises a step of introducing the resin pellets and water into a first tube body, and a step of conveying the resin pellets and the water toward a discharge opening in the first tube body, and cleaning the resin pellets by removing foreign matters from the surfaces of the resin pellets by water flow.

    Abstract: In a conventionally used injection molding apparatus, undried resin pellet is put in a drier of a predetermined temperature and water and gas in the undried resin pellet is completely removed, and the dried pellet deprived of water and gas is thrown into the injection molding apparatus. It is therefore necessary to carefully control quality of water and gas of pellet before pellet is thrown into the injection molding apparatus. In injection molding of undried resin pellet, evaluate injected resin, control operation conditions such as the feeding amount of pellet and the decompression degree, and determine the best operation conditions and the best accumulation amount wherein excellent articles are obtained. The accumulation amount of pellet fed in an injection molding chamber is detected, and feeding to the injection molding chamber is controlled upon the detection information. In the process of melting of the injection molding chamber, water and gas vaporized from pellet is discharged to the atmosphere under decompression.

    Abstract: The invention relates to granulates based on at least one polymer that can be thermally treated, said granulates having a content of concave points of less than 10 % and being convex at all other points. Said content is determined using the average value of the ratios of the contour surface to the total contour surface for a group of granulates, by means of reflection interference spectroscopy.

    Abstract: Reinforced plastic pellets comprise thermoplastic material and reinforcement particles that are less than 15 % of a total volume of the pellets, and at least 40 % have a thickness of less than 50 nanometers. A manifold (56) has at least two spaced valve gates (64) that are independently opened and closed as directed by a controller (68) to selectively communicate the manifold to a cavity. A primary injection pressure is applied to the plasticized pellet material in the manifold (56) to fill the cavity through sequential opening and closing of the gates (64). A lower secondary injection pressure is applied to the material in the manifold to continue filling the cavity. The gates are closed to seal the manifold from the cavity when the cavity is filled. The material is held within the manifold in compression by the valves while the cavity is open to prevent expansion of the material.
