A method produces a foamed decorable support part for a motor vehicle, wherein a sheet with a base layer, an adhesive layer and a protective layer is laminated in an injection-molding process.

An injection molded thermoplastic preform for blow moulding to form a container, the preform base of a central part having a first, downwardly and radially inwardly tapering portion therebetween which increases in thickness from a radially outer end of the first tapering portion adjacent to the hollow transition portion to a radially inner end of the first tapering portion adjacent to the gate part and the middle part opposite the gate part can allow the injected resin to be urged back through the gate at the end of the injection moulding cycle at a lower fluid pressure in the vicinity of the gate which is associated with high resin temperatures. The technical effect achieved by the first tapering portion is that crystallinity in the gate area is minimized or eliminated, which avoids or minimizes partial blocking of the gate which would otherwise restrict the injected resin from being urged back through the gate at the end of the injection moulding cycle.

An injection molded part for a motor vehicle includes a film having a scratch-resistant layer, a plastic substrate molded to the film, wherein the plastic substrate is at least partially transparent or translucent, and a scratch-resistant coating molded to the plastic substrate on a side opposite the film.

A process of making a part with improved mechanical performance and improved impact performance compared to a solid part with a same weight by a disclosed foaming process. The process including introducing a glass fiber filled polymeric material to a hopper (128) of an injection molding machine, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit (100), and pressurizing the plasticizing unit (100) of the injection molding machine with a blowing agent. The process further including dissolving the blowing agent into the melt, injecting the melt into a mold cavity (408) of a mold up to 100% of volume, and reconfiguring the mold to increase a size of the mold cavity (408) after a predetermined time after a delivery of the melt. A part made by the process and the device for making the part are also disclosed.

An apparatus includes a mold. The mold has a first mold part with a first interior surface and a second mold part with a second interior surface. The apparatus additionally includes a movable member disposed proximate the mold. The movable member is movable between a first position and a second position. In the first position the movable member cooperates with the first interior surface and second interior surface to define a first mold cavity, and in the second position the movable member cooperates with the first interior surface and second interior surface to define a second mold cavity. The second mold cavity has a shape distinct from the first mold cavity.

The present invention provides a method for manufacturing a molded foam product which can reduce blisters on the surface and foaming failure in injection molding of a molten resin containing a fluid in a supercritical state even in the case of manufacturing a molded product designed to have a small thickness, thereby giving a molded foam product having excellent heat insulation. The method of the present invention is a method for manufacturing a molded foam product through injection molding of a molten resin containing a fluid in a supercritical state, the method including a step of injecting the molten resin into a cavity formed in a mold and moving a portion of the mold to increase the volume of the cavity before the molten resin injected into the cavity completely solidifies, the cavity being communicated only with a single resin injection port, the mold having a dimple which has a substantially hemispherical shape and is situated to face the resin injection port, the mold having a minimum gap size of 0.2 mm or greater in the cavity during injection of the molten resin.

An injection molded part for a motor vehicle includes a film having a scratch-resistant layer, a plastic substrate molded to the film, wherein the plastic substrate is at least partially transparent or translucent, and a scratch-resistant coating molded to the plastic substrate on a side opposite the film.

An injection moulded thermoplastic preform for blow moulding to form a container, the preform comprising a lower closed base portion, a hollow body portion, a hollow transition portion between the lower closed base portion and the hollow body portion, and an upper open end portion adjacent to an upper part of the hollow body portion, wherein the closed base portion comprises a central portion which extends over at least 50% of an internal radius of a lower end of the hollow body portion and is either substantially flat or has a shallow concave or convex internal curvature, and the transition portion comprises an upwardly and radially outwardly tapering portion extending away from the central portion to connect to the hollow body portion, the tapering portion being inclined at an angle of from 1 to 20 degrees to a longitudinal axis of the preform and the tapering portion increasing in thickness from the central portion to the hollow body portion. Also disclosed is a method of injection moulding the thermoplastic preform.
