  • Patent number: 10974435
    Abstract: A method for producing a foamed blow-molded article, which includes extruding a physical blowing agent-containing foamable molten resin downwardly through a annular die to form a tubular foamed parison, clamping the foamed parison between split molds, and then blow molding it. At the latest before completion of the clamping of the foamed parison between the split molds, a gas is blown toward an inner peripheral surface of an upper portion of the foamed parison, the bottom portion of which has been closed, from a gas ejection outlet located within the foamed parison at a position immediately below the annular die to widen the foamed parison.

  • Patent number: 10850424
    Abstract: A method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring the mixture into a mold (20) an upper face being exposed; engraving the exposed upper face with a predefined precise pattern of grooves (30) coinciding with a pattern of thin veins to be obtained; impregnating at least the inner faces (31) of the grooves (30) with a moldable hardenable fluid mixture of a second material (12), the color of both materials being different; causing the collapse and closure of the grooves, a visible pattern of thin veins of a second material with a natural look being left behind; curing the artificial stone slab by subjecting it to vibration, compression and vacuum until the fluid mixtures of the first material and of the second material are hardened.

  • Patent number: 10780656
    Abstract: An apparatus for preparation of a continuous composite element formed of reinforcement fibers impregnated with a resin that includes photo-initiators for curing. Reinforcement fibers are pulled through a vacuum chamber (110) and then a vertical impregnation chamber (122) where impregnation with the resin occurs. The elongate composite is then deposited onto a rotating wheel of conformation (140). During rotation, a radiation source (146) such as e.g., LEDs (light emitting diodes) are used to activate the photo-initiators and provide at least partial curing of the resin. From the wheel of conformation, the continuous composite element is passed along a vertical course (148) where additional radiation sources (150) activate the photo-initiators and provided additional curing.

  • Patent number: 10766190
    Abstract: Additive manufacturing apparatus including a build module is presented. The build module includes a support structure; a powder supply chamber formed in the support structure; and powder applicator disposed on the support structure and located proximate to the powder supply chamber. The build module further includes a powder recovery chamber and a plurality of build plates spatially disposed around the powder recovery chamber, the plurality of build plates configured to move around the powder recovery chamber. The build module is configured such that during an additive manufacturing process step, a build plate of the plurality of build plates is disposed between the powder supply chamber and the powder recovery chamber, and the powder applicator is configured to distribute a required amount of the powder material from the powder supply chamber on the build plate and deposit any excess powder material in the powder recovery chamber. Related processes are also presented.

  • Patent number: 10751924
    Abstract: A method for making an activatable material having a handling film layer thereon, comprising the steps of providing a continuous mass of a polymeric material having a longitudinal axis and being capable of adhering to a metal surface; applying a handling layer (e.g., film) over at least one side of the mass; forming stress relief indentations in the mass, with the handling layer at least partially extending into the indentations, wherein the stress relief indentations allow a resulting part to be applied in conforming geometry with a surface to which it is applied. The teachings also contemplate parts made by the above method and use thereof to bond to surfaces having a non-planar portion.

  • Patent number: 10723080
    Abstract: A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.

  • Patent number: 10632667
    Abstract: A manufacturing procedure for ceiling trims for vehicles. The ceiling trims comprise at least one first coating sheet and at least one second coating sheet that extend along one of the sides of the first sheet, joined via a layer of heat-stable polyurethane adhesive, comprising a step of applying a gas-phase catalyst on such sheets through a thermoforming mould that starts before the mould is completely closed and ends before the mould is completely opened. As a result of the application of a gas-phase catalyst we prevent the use of demoulding agents to facilitate extraction of the ceiling trim formed inside the mould.
