A halogen-free modified high-filling recyclable plastic board is provided in this disclosure, which includes a substrate layer and a printed layer and a protective layer disposed sequentially on the substrate layer from bottom to top. Raw materials of the substrate layer include, by weight in percent, 20 to 25% of PEAT resin, 70 to 75% of stone powder, 0.5 to 0.8% of chain extender, 1 to 2% of white mineral oil, 3 to 6% PE, and 0.4 to 0.8% stearic acid. The plastic board according to the present disclosure is formed using a hot press process, without glue bonding and with good integrity; and the manufactured board is large in surface tension, its surface is easy to be processed and a substrate layer thereof has good compatibility with a printed layer and a protective layer, which can be recycled as a whole.

Resin-molded articles, to which such advantages as strength, rigidness and light weight are secured thanks to kneading with fibers, and which has excellent surface characteristics such as smoothness of the surface and beauty in the appearance, and resistance against weather, ultraviolet rays and light are provided.

A method of recycling a PET-containing material comprises: (1) providing a polymer crystallizer comprising at least one heating element, and at least one blower; (2) providing an MRS extruder having an MRS section comprising a plurality of satellite screws; (3) providing a vacuum pump in fluid communication with the MRS section; (4) grinding and washing the PET-containing material; (5) heating the PET-containing material in the crystallizer to at least partially dry the PET-containing material; (6) shearing the PET-containing material in the MRS extruder to produce a PET-containing melt; (7) increasing a surface area of the PET-containing melt by distributing the PET-containing melt across a plurality of satellite screws in the MRS extruder; (8) drawing off vapors from the PET-containing melt by reducing the pressure in the MRS section with the vacuum pump; (9) collating the PET-containing melt in the MRS extruder; and (10) extruding a recycled PET-containing material.

A method of manufacturing a fuel tank includes: passing a hollow molten resin projection, that projects-out in a wall-thickness direction and is formed at a molten resin sheet that becomes a tank structural member structuring a tank main body, through a mounting hole of a part-to-be-mounted that is placed on the molten resin sheet; and pressurizing the molten resin projection from an inner side, and causing at least a portion of the molten resin projection to jut-out to a peripheral portion of the mounting hole of the part-to-be-mounted.

A formed film includes a first surface generally located in a first plane, a second surface generally located in a second plane parallel to and spaced from the first plane, and a third surface generally located in a third plane parallel to and spaced from the first plane and the second plane, in between the first plane and the second plane. A porous structure extends between the second surface and the third surface. A plurality of raised areas have sidewalls that extend between the first surface and the third surface, and top portions that define the first surface. The plurality of sidewalls, the porous structure, and the first plane define a plurality of gathering volumes.

A receptacle stabilizer for stabilizing a receptacle may include a cover portion defining a cavity and at least one weight portion disposed within the cavity of the cover portion. The cover portion may include a top wall, a plurality of sidewalls extending downward from the top wall, and a lip portion extending outward from the plurality of sidewalls. The cavity may be defined between the top wall and the plurality of side walls. A method of forming a receptacle stabilizer may include heating a material to be formed into a cover portion of the receptacle stabilizer, placing the heated material over a mold, vacuum forming the heated material into the mold and forming the cover portion, and disposing at least one weight portion into a cavity of the cover portion.

A composite material molding method is provided for forming a composite material. The molding includes disposing carbon fiber in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When a threshold value of the pressure inside the cavity is set to a pressure that is lower than the clamping pressure and the resin is injected into the cavity while exerting an injection pressure that is equal to or greater than the clamping pressure on the resin until the pressure inside the cavity reaches the threshold value. Then, after the pressure inside the cavity has reached the threshold value, the inside of the cavity is suctioned.

Thermal curing of a potting material within a hole in a surface of a composite material is described utilizing a flexible vacuum compression device that includes a chemical-based heating pack. The vacuum compression device includes an internal compartment within a cavity that retains the chemical-based heating pack, and a vacuum port having a passage into the cavity. An end of the vacuum compression device includes an interface that forms an air-tight seal between the cavity and the surface when applied to a surface of the composite material. Drawing a vacuum via the vacuum port collapses the vacuum compression device and positions the chemical-based heating pack proximate to the surface, enabling heat from the chemical-based heating pack to thermally cure the potting material.

Described are methods of two-dimensionally and three-dimensionally forming an article of wear using vacuum forming in an automated process. In the two-dimensional method, the article of wear comprises a generally flat shape with three-dimensional features molded into the first material layer.
