The present disclosure relates to a process and article produced by injection molding. More particularly, a process and article produced by injection molding, that provides a part with one or more locations of a reduced density where such part competes in mechanical property characteristics with parts, such as vehicular components, otherwise produced from metallic materials.

A tool is disclosed for the production of foamed insulation boards with two side faces lying opposite one another and all-round end faces such as facade insulation boards for insulating buildings. The tool has two mold halves, each having a mold frame and a mold base. The two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced, with the mold frames defining or bounding the end faces of the insulation board to be produced and the mold base defining or bounding the side faces. A setting device sets the position of the two mold halves in a plane parallel to the mold bases. The setting device is designed for stepless setting of the position of the two mold halves relative to one another.

The present disclosure provides a resin seal member capable of reducing the cost while preventing a reduction in the sealing performance due to an influence of heat or pressure in accordance with a usage environment. The present disclosure provides a resin seal member (20) including a foamed resin part (13). This resin seal member (20) includes a convex part (12b) having a foaming ratio lower than that of the foamed resin part (13). The convex part (12b) is provided in an end part of the foamed resin part (13). The resin seal member (20) is able to reduce the cost while preventing the reduction in the sealing performance due to the influence of heat or pressure in accordance with the usage environment.

The present disclosure provides a mold of a resin body capable of reducing the cost of manufacturing a resin body including a resin base material and a foamed resin part provided on the resin base material. This mold is a mold of a resin body including resin base material molding die parts for molding a resin base material. The mold includes: a sliding part capable of sliding inside a foamed resin part molding cavity that communicates with a resin base material molding cavity of the resin base material molding die parts. The sliding part is swingably floated in a direction perpendicular to a sliding surface on which the sliding part slides. In the process of molding the resin base material, the sliding part blocks an opening part that communicates from the resin base material molding cavity to the foamed resin part molding cavity.

The present invention relates to an injection molded product, an expanded foam product, a method of injection molding a plastisol an expandable plastic embryo during which the foaming of the plastic embryo is suppressed throughout the molding operation. The invention further relates to a mold and an injection molding device.

There is described a method of creating a hinge in a body of expandable material, said body being substantially flat and having at least two planar regions connected by said hinge to facilitate folding of the planar regions about said hinge, comprising: expanding said expandable material to form said body; creating a region of excess expandable material in said body adjacent said hinge; and compressing said region of excess expandable material into the hinge of said body after the expandable material has fused to create a hinge having a concentrated volume of expanded material when compared to said at least two planar regions of said body.

A method for producing a molded part, in particular a component of a sporting good, includes providing a mixture of a polymer melt and a foaming agent and injecting the mixture into a mold. The method includes solidifying at least a first portion of the molded part without foaming and at least a second portion of the molded part after foaming inside the mold, wherein the mixture includes a polymer having an average molecular mass corresponding to a viscosity number 130 ml/g, preferably 170 ml/g, more preferably 190 ml/g and most preferably 225 ml/g, wherein the viscosity number is determined via solution viscometry according to the ISO 307 standard.

A method for manufacturing an insulation block, preferably an insulation plate, in which method the casting mold is adjusted to a desired size by moving at least one wall of the casting mold, the pre-expanded polystyrene, polypropylene or polyethylene beads are led to the casting mold, the pre-expanded polymer beads are steamed in the casting mold, and the formed finished insulation block is removed from the mold. In a method according to the invention at least one wall of the casting mold is moved during the steaming and/or during the cooling phase after the steaming.

A continuous forming apparatus for molding foam material into foam products that includes a first endless belt and a second endless belt that cooperates with the first endless belt to mold the foam material. The continuous forming apparatus may also include a first plurality of cleats and a second plurality of cleats opposed to the first plurality of cleats that support the first endless belt and the second endless belt respectively. The first plurality of cleats may include a three-dimensional abutment surface that provides transverse and lateral support to the first endless belt. Additionally, the continuous forming apparatus may include a first frame disposed to support the first plurality of cleats, a second frame disposed to support the second plurality of cleats, and a drive mechanism for imparting motion to the first endless belt, the second endless belt, the first plurality of cleats, and the second plurality of cleats.

A device for manufacturing a support for the human body, of the type including a mold including a lower female portion and an upper male portion capable of being coupled with one another so as to define at least one cavity between them inside which at least one material in the fluid state intended to make the support can be poured. The female portion of the mold includes at least one mobile block including at least two different surfaces suitable for making up respective different bottoms of said cavity for separate pouring steps of at least one material in the fluid state foreseen in the support. A process for manufacturing a support for the human body is moreover presented.
