A mold for in-mold foam molding of polyolefin-based resin that prevents the occurrence of burrs at the time of molding to control productivity reduction and labor cost rising caused by burr trimming. A mold is configured to mold an insert member including an embedded part to be embedded into a foaming molded body formed from a polyolefin-based resin and a protrusion part protruding from the foaming molded body integrally with the foaming molded body. The mold is provided with an accommodation concave part capable of accommodating the protrusion part and an opening/closing part capable of opening and closing a cavity-side opening in conjunction with insertion and extraction of the protrusion part into and from the accommodation concave part such that, while the protrusion part is inserted into the accommodation concave part, and the cavity-side opening is closed.

Described herein are helmets comprising at least one surface reinforcing component. In some embodiments the surface reinforcing component comprises at least one anchoring feature embedded in a structural feature of the helmet, such as a force absorbing element. In other embodiments, the surface reinforcing component comprises fasteners configured to mate with a respective fastener on a shell of the helmet.

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.

There is provided an insulation foam in a tubular form, comprising at least one seamless layer of crosslinked polyethylene (PEX) closed-cell physical foam. The tubular foam can favourably be used to thermally insulate tubes that convey water, refrigerants or other fluids, in particular, copper tubes for Heating, Ventilation, Air-Conditioning and Refrigeration (HVAC&R) applications, as well as plastic tubes for use in domestic plumbing systems, hydronic radiant heating and cooling systems. There is also provided a method for manufacturing a crosslinked polyethylene (PEX) closed-cell physical foam in seamless tubular form, an insulation foam material using the same and a polymer blend for its manufacturing.

A method for manufacturing an interior lining part, includes producing a skin; placing the skin in a foaming mold with a support layer; foaming an intermediate layer; cutting out an area of the skin producing a cutout area of the skin; placing a piece of adhesive tape or film in the cutout area, the piece of adhesive tape or film being placed in between the skin and the intermediate foam layer; and placing an insert in the cut out area of the skin. A method for manufacturing an interior lining part, includes producing a skin by rotational molding; placing a piece of adhesive tape or film in the cutout area, the piece of adhesive tape or film being placed in between the skin and the intermediate foam layer; placing the skin in a foaming mold with a support layer; foaming an intermediate layer; cutting out an area of the skin producing a cutout area of the skin; and placing an insert in the cut out area of the skin.

A formation assembly for use in manufacturing a reinforced insulation panel including a foam material and a reinforcing structure includes a back plate including a first surface configured to receive the foam material, and a first support sheet spaced from the first surface to form a gap therebetween, wherein the first support sheet supports the reinforcing structure. The formation assembly also includes a second support sheet spaced from the first support sheet, wherein the second support sheet defines an upper boundary of the reinforced insulation panel. A rigid structure is coupled to the second support sheet, wherein the rigid structure restricts movement of the reinforced insulation panel.

A padding assembly for a vehicle seat includes a foam mass defining a first side and a bladder unit recessed into the first side of the foam mass within an impression defined by the bladder unit. The bladder unit has a first surface adhered to the foam mass on the first side thereof and defines an impression along the first side of the foam mass. The padding assembly further includes an air line coupled with the bladder unit and extending at least partially through the foam mass.

Provided are a vehicle seat member in which even when a foamed resin molded body forming the vehicle seat member shrinks after being demolded, influence of the shrinkage behavior on a frame member embedded in the foamed resin molded body can be prevented, and thus a change in the position of a protrusion, which serves as a part to be anchored to a vehicle body, of the frame member can be prevented, whereby the vehicle seat member can be attached to the vehicle body side easily and reliably, and a vehicle seat including such a vehicle seat member. A vehicle seat member includes a foamed resin molded body and a frame member integrally formed therewith, the frame member including a body portion embedded in the foamed resin molded body and protrusions each protruding from the body portion and having a tip end protruding outward from the foamed resin molded body.
