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.

Described are methods for the manufacture of a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such a method, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. According to an aspect of the invention, a method for the manufacture of a plastic component, in particular a cushioning element for sports apparel, is provided which includes loading a mold with a first material which includes particles of an expanded material, and, during loading the mold, pre-heating the particles by supplying energy, wherein the energy is supplied in the form of at least one electromagnetic field.

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.

Described herein are expandable foaming molds. The foaming molds described herein permit mold boundaries to expand along with the expanding polymer and thereby conform to the foaming dynamics of the polymer material. By modifying the temperature and pressure applied to the mold devices described herein, the properties of the resulting foamed polymer can be fine-tuned for specific applications.

An interior part for a vehicle is formed by core-back expansion molding. The interior part includes a foamed plastic body formed by injecting a foamable plastic resin into a mold and separating the mold portions of the mold to allow foaming expansion of the foamable plastic resin. An edge portion of the foamed plastic body includes a projecting freeze section and a core-back expansion radius located adjacent to the projecting freeze section. The projecting freeze section is formed in a freeze seal area of the mold adjacent a parting line to help prevent excessive flashing of material at the parting line during separation.

The invention relates to a crack-split moulding tool for producing a foam particle part, having two mould halves (2, 3). The mould halves (2, 3) are pivotably mounted relative to one another such that they can be arranged at a varying distance from each other in certain sections when being filled with foam particles and when pressing together, are moved together at a varying distance until in a closed position, due to a pivoting movement. As a result, it is possible to homogeneously compress areas of the moulding cavity (6) having a different thickness and to compress in a different manner, area having the same thickness.

The invention relates to an apparatus for the manufacture of a particle foam component, said apparatus comprising a molding tool limiting a molding space, wherein, adjacent to the molding space, at least two capacitor plates are arranged which are connected to a radiation source for electromagnetic radiation, wherein the radiation source for electromagnetic radiation is designed for emitting electromagnetic radiation, and wherein the molding tool is formed of at least two molding halves, wherein at least one of the molding halves is made from an electrically conducting material and forms one of the capacitor plates.

Described are methods for the manufacture of a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such a method, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. According to an aspect of the invention, a method for the manufacture of a plastic component, in particular a cushioning element for sports apparel, is provided which includes loading a mold with a first material which includes particles of an expanded material, and, during loading the mold, pre-heating the particles by supplying energy, wherein the energy is supplied in the form of at least one electromagnetic field.

A method of molding a collapsible, foam plastic container; the method employs two half-molds defining a molding chamber negatively reproducing the container in an erect work configuration, and forms a hinge for each lateral wall of the container when molding the container; each hinge being formed by a parting member which is inserted through the molding chamber at the hinge to be formed, and by a compression member opposite the parting member and which is moved towards the parting member to form, on the lateral wall, a small-section, higher-density portion defining the respective hinge.

The invention relates to a foaming and punching tool for producing foamed products from structural foam, and to a method for producing such foamed products.
