Also provided herein is a thermoplastic composition, particularly intended to be extruded or injection moulded, having one or more copolymers of ethylene and acrylate(s) at a content ranging from 0.1 to 20 wt. %, and one or more thermoplastic polymers.

METHOD FOR PRODUCING GRAMOPHONE RECORDS BY INJECTION MOULDING

A method for producing gramophone records by injection moulding, comprises the steps of heating polymeric material to liquefy said material, supplying liquid polymeric material under pressure from a feed zone to a space between two mould parts via a nozzle. The liquid polymeric material is passed through a single passage located in one of the mould parts and forced under pressure through the nozzle into said space. Polyethylene terephthalate isophthalic acid modified copolymer is used as said polymeric material.

The skin (1) comprises at least an outer elastomeric layer (5) with an inner surface and an outer surface and at least one operating element (8A) which is adhered to the inner surface of the outer skin layer (5). The operating element (8A) is intended to be connected to an electric or electronic component to enable to control the operation of this component. In order to indicate the location of the operating element (8A) in the skin (1) with a minimal distortion of the visual appearance of the skin, the operating surface (9) of the operating element (8A) extends in a first area (11) of the visible surface of said skin (1), which first area (11) has a first surface texture which is different from the surface texture of the surrounding area (12) of the visible surface of the skin. Both textures may in particular produce a different gloss and the first area (11) may further be provided with surface relief elements (16, 17).

Plural ejector pins are made to project before a molten resin containing reinforcing fibers is injected into an inside of a cavity through pin point gates in a web forming portion in the inside of the cavity and at positions outside the pin point gates in a radial direction. The ejector pins are retracted from the inside of the cavity after a flow of the molten resin containing reinforcing fibers injected into the inside of the cavity through the pin point gates impinges on the ejector pins and is divided and before a tooth portion forming portion in the inside of the cavity is filled with the molten resin containing reinforcing fibers. Accordingly, weld lines which extend along the radial direction are formed at positions outside the ejector pins in the radial direction, and the molten resin is filled in portions formed after the ejector pins are retracted.

METHOD OF INJECTION MOLDING PREFORM

A method of injection molding a test tube-shaped preform for biaxial stretch blow molding includes supplying a major material resin from outer and inner flow paths to a combined flow path for a predetermined time and rate. For a period of time within a range of the predetermined time period during which the major material resin is supplied, the intermediate layer resin is simultaneously supplied from the middle flow path to the combined flow path at a second predetermined supplying rate. A columnar laminated molten resin is injected into a cavity of a metal mold connected to a tip of the nozzle through a gate to fill the cavity, the columnar laminated molten resin being composed of the major material resin and the intermediate layer resin formed in the major material resin in a laminated manner that are combined into a columnar shape at the combined flow path.
