A foamable cross-linkable thermoplastic material comprises a matrix polymer of any one or a mixture of two or more of polyethylene (PE), ethylene vinyl acetate copolymer (EVA) and polypropylene (PP), a cross-linking agent, and a foaming agent. A weight ratio of the cross-linking agent to the matrix polymer is 1-5:100. A weight ratio of the foaming agent to the matrix polymer is 1-5:100. A cross-linking foaming temperature of the thermoplastic material is equal to or higher than the melting point of the matrix polymer.

An injection molding device includes: a material storage unit storing a material; a drive motor; a plasticization unit including a rotor that rotates by rotation of the drive motor, a barrel facing the rotor, and a heater, and configured to plasticize and flow out the material supplied from the material storage unit; a nozzle through which the material after plasticization is injected toward a mold from the plasticization unit; and a material drying unit configured to collect waste heat of the drive motor and dry the material in the material storage unit.

A device for the cooling and extraction of preforms for the manufacture of plastic containers, including at least one grip assembly which forms a number of receptacles for respective preforms and a component for transferring the preforms that are still warm from an injection molding device to the grip assembly, and a cooling and extraction assembly which includes a cooling plate supporting a number of cooling channels. The cooling and extraction assembly includes an unloading plate which is arranged on the opposite side of the grip assembly with respect to the cooling plate, and supporting grip bodies which can be moved on command in order to pass through the cooling plate so as to engage selectively, with the cooling plate in the closer position, with a respective preform in order to allow its extraction from the respective receptacle.

A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.

An apparatus for the manufacture and unloading of preforms for the manufacture of plastic containers includes a device for the injection molding of preforms and a device for the cooling and extraction of the preforms from the molding device, and further includes a device for the selective extraction of a predetermined subset of preforms supported by the unloading plate in an orderly manner along at least one pickup direction. The apparatus also includes a component for the orderly transfer of the predetermined subset of preforms to a control and inspection device adapted to perform at least one control on the predetermined subset of preforms.
