The disclosure is directed to a solid part, and a device and process of making the solid part. The process includes introducing a glass fiber filled polymeric material to a hopper of an injection molding machine, where the glass fibers have a pre-molding length, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit, pressurizing the plasticizing unit of the injection molding machine with a blowing agent, dissolving the blowing agent into the melt, injecting the melt into a mold cavity up to 100% of volume, and forming the solid part.

Embodiments of the invention are directed to a molding system and kit for molding a modeling compound. The molding system is generally comprised of an openable interlocking molding device, the openable interlocking molding device is configured to cast external features onto a modeling compound surface by securing the modeling compound within a molding cavity of the openable interlocking molding device. Further, the molding system includes a substrate with movable joints that is configured to be enveloped by the modeling compound prior to casting the external features onto the modeling compound by the interlocking molding device.

Methods and systems for designing and manufacturing a mathematically fair N-sided die are disclosed. An example method can comprise selecting an irregular polyhedron to serve as a die, and determining a center of mass of the selected irregular polyhedron die. In an aspect, a size of each face of the irregular polyhedron can be selected such that a solid angle subtended by each face from the center of mass of the selected irregular polyhedron can be equal. In an aspect a system comprising an injection molding apparatus can be used to form the die.

The invention discloses a recyclable toy and the manufacturing method thereof, the method comprising the following steps: S1, according to the designed shape of the toy, manufacturing a pulp sucking molding die and a hot press shaping die with a corresponding shape, and conducting trimming by a die cutter; S2, placing the pulp sucking molding die in a pulp containing tank so that the pulp sucking molding die sucks the pulp, and demolding to obtain a toy wet green; S3, using the hot press shaping die to hot press the toy wet green for shaping by a hot press machine so as to obtain the recyclable toy. The invention provides a toy and a method using pulp as a raw material. The manufactured toy has good quality, contains recyclable material and is environmentally friendly, which is firstly seen in the field of toy manufacturing.

A method, composition and kit that enable the creation of a three-dimensional object by the action of placing at least one molding composition of at least one color or type into a mold, and then subsequently placing the mold within a liquid hardening agent to cure and solidify the molding composition enough so the three-dimensional object can be removed from the mold and become an object of display or a toy to be played with.

Scratch resistant polymer composition, in particular for the manufacturing of rigid, scratch resistant and dimensionally stable building bricks, comprising: a) a bio-based HDPE granulate, produced from ethanol or ethylene obtained from biomass; b) an amorphous polymer and/or (semi)crystalline polymer; c) optionally a mineral filler and optionally a colouring pigment; Furthermore, a method for manufacturing an injection moulding article from the scratch resistant polymer composition is disclosed.

The present invention relates to toy building elements made of a biopolymeric material. The present invention also relates to a method of manufacturing said toy building elements.

The present invention relates to a method for the manufacture of a toy building element made of a polymeric material using an additive manufacturing technique as the manufacturing process. The present invention also relates to a toy building element produced by said additive manufacturing process.

A magnet is embedded in a flexible elastic material, providing a means of temporarily connecting the flexible elastic material to ferromagnetic objects. A rigid cup provides a container for anchoring the magnet in the flexible elastic material. The cup also provides a structure to bind with the flexible elastic material. The magnet rests in the base of the cup, which extends past the surface of the material, allowing the magnet's forces to extend outside the base of the cup. The remainder of the cup resides within the material.

A plastic article is recited having a plastic shell including walls defining a cavity. Within the cavity is an in-situ foam core including expanded polymer beads. A layer of the expanded polymer beads includes a layer of distorted beads adjacent to the walls. The in-situ foam core has a thermal bond to the walls.
