In order to be capable of reliably supplying a prescribed amount of fiber materials into a heating cylinder for each cycle and continuously manufacturing a homogeneous composite material, a plasticizing unit is provided with a fiber supply device 3 that supplies prescribed amount of fiber materials A2 having a prescribed length into the heating cylinder 1. The fiber supply device 3 is provided with: a cutting section 12 that cuts off a long fiber material A1 pulled out from a reel 11 into a prescribed length; a pressure-feeding section 13 that presses the fiber materials A2 having the prescribed length cut off by the cutting section 12 into the heating cylinder 1; and a fiber transfer device 45 that forcibly transfers the fiber materials A2 accumulated in the cutting section 12 to the pressure-feeding section 13. The pressure-feeding section 13 is constituted by a press cylinder 41 and a press piston 42, and the fiber transfer device 45 is constituted by a vacuum device.

A decorative panel comprising a plate-shaped carrier made of a wood plastic composite (WPC) material, wherein the plate-shaped carrier comprises a profile and/or a cut edge in at least one edge region, and wherein the profile and/or the cut edge has a substantially sealed surface. A method for producing such panel including a step of subjecting a surface of a profile and/or cut edge to a thermal treatment to at least partially melt the WPC material in the region of the profile and seal the surface.

A composite panel configured for use with a sidewall of a trailer includes an outer metal sheet, an inner metal sheet, and a core member positioned between the inner and outer metal sheets. The core member includes a plurality of apertures formed therethrough such that each aperture extends from an inner surface of the core member to an outer surface of the core member. Illustratively, the plurality of apertures is covered by the inner and outer metal sheets.

A method uses retrofitably-attachable pre-formed shell to cover exposed areas of existing stamped/formed chrome or painted truck bumpers, providing a unique re-useable decorative/protective plastic shell cover, the edges of which are tucked under the existing trim pieces of the bumper as a main attachment mechanism. The formed shells can be used to cover existing minor damage on the bumper. Light-passing images can be incorporated on the bumper shells, and backlit without changes to the bumper or deviation from the original surface profile of the bumper. Methods of forming the shells include vacuum forming, and include forming a raised perimeter guide, allowing the molded parts to be trimmed using a rotary cutting tool that follows the perimeter guide, thus reducing capital investment and tooling costs.

A device for producing a mold part. The device includes a first tool component and a second tool component. The first tool component has a first pressing surface and a first cavity. The second tool component has second pressing surface, a second cavity, and a nozzle configured to supply a liquefied synthetic material. The first and second cavities are configured to overlap at least partially in a cross-section perpendicular to the first and second pressing surfaces when the first and second pressing surface face each other. At least one of the first and second tool components is configured to be movable relative to another.

A process for preparing a composite part, the process comprising: recovering unsaturated resin prepreg scrap; combining the recovered unsaturated resin prepreg scrap with a second resinous thermosetting component; and co-molding the prepreg scrap and resinous thermosetting component together under a pressure of 25 to 4000 psi and at a temperature of 100-400 F.

A procedure wherein a tubular high molecular weight polymer film which has been longitudinally stretched and therefore is longitudinally shrinkable, is converted by helical cutting to second polymer film, which then is heated and relaxed in order to partly or totally eliminate the shrinkability, whereby one edge of the helically cut film, inevitably becomes longer than the other edge, referring to a relaxed stated, characterised in that second film is converted to third film by continuously advancing second film in a first direction towards a lineary zone which extends perpendicularly to the edges of the cut film, while heating the film to a temperature lower than but close to its melting range, and in direct succession hereto moving the heated film at velocity (v) in a second direction which forms a small angle (a) to the first direction, the velocity (v) and angle (a) being selected to reduce or totally eliminate the difference between the lengths of the edges.

The present application discloses a preparation method of SM non-woven fabrics for roof anti-slip, which belongs to the technical field of roofing materials, comprising preparing spunbond non-woven fabric raw materials, preparing spunbond non-woven fabrics, preparing meltblown non-woven fabric raw materials, preparing primary SM non-woven fabrics, and post-processing; the spunbond non-woven fabric raw materials are prepared by uniformly mixing polypropylene with a low melt flow index, polypropylene with a high melt flow index, sodium alginate, antioxidant 1010, zinc stearate, ultraviolet absorber UV-531, polyvinyl alcohol, reinforcing agent, adhesive agent, and nano titanium dioxide. The present application can avoid the problem that the SM non-woven fabrics cannot be fully bonded together and are easy to delaminate when being combined, can also solve the problem of fabric breakage during high-speed production, and can also improve the wear resistance, strength, and stiffness of SM non-woven fabrics. The prepared SM non-woven fabrics have low production costs, are easy to recycle, and have good environmental performances.

A method of manufacturing a custom sized plastic tote lighter in weight than heretofore known custom sized plastic totes is provided. The method comprises separating an injection molded tote into upper and lower portions by cutting the injection molded tote. A sleeve or middle portion of plastic material is secured to the upper and lower portions of the injection molded tote to create a custom sized plastic tote of a desired height. Alternatively, portions of different injection molded totes may be used to create a custom sized plastic tote. The sleeve may be made from different materials and may be made of multiple pieces.
