An apparatus for molding a part having ferromagnetic pigments is provided by the present disclosure. A magnetic field, generated by an electromagnet, is set up adjacent a wall of the part cavity that will define an A-surface of the part. A ferromagnetic pigment is combined with the resin. When the electromagnet is activated, the magnetic field attracts the ferromagnetic pigment to collect near the cavity wall that will define the A-surface. The apparatus of the present disclosure includes a mold, a part cavity formed in the mold, and an electromagnet positioned adjacent the part cavity whereby a magnetic field can be exerted on the part cavity. The electromagnet may be of any of several types, including a coil or a wire grid. The electromagnet may be embedded in the mold or may be placed adjacent to the mold.

A feeding apparatus is mounted to an injection molding apparatus defining an injecting space for receiving multiple pellets, and includes a feeding device defining a feeding space that has a delivering space portion and a feeding space portion spatially intercommunicating the delivering space portion and the injecting space, a supplying device defining a supplying space spatially communicating with the delivering space portion and being operable to allow or interrupt spatial communication with the supplying space and the delivering space portion, and an air suction device mounted to the feeding device and being operable to draw air from the injecting space and the feeding space. The pellets move from the supplying device into the injecting space.

A gardening glove consisting of a glove liner defining a plurality of fingers, a thumb, and a palm is provided. The glove liner is placed on a first glove mandrel and received inside an injection mold configured to inject hot liquid PVC material on the glove liner's palm, fingers, and thumb, creating patterns of raised nodules that facilitate digging, for example.

The device for the suction of air in injection molds and the subsequent expulsion of molded pieces has a Venturi ejector connected to a first valve, that when the mold is closed causes the suction of air in a mold cavity, having at least one insert made from porous material through which and by means of a communication duct that defines a suction circuit, and a second valve, that after the solidification of the plastic material, causes the air to be blown towards the at least one insert made of porous material, cleaning the at least one insert made of porous material. The volume of air to be reduced in the second part of the injection cycle with the same empirical value of 90% efficiency of the Venturi ejector.

A molding process according to one embodiment of the present disclosure includes injecting a first molding material into a mold cavity of a mold, the mold cavity formed by at least a mold cavity portion of a first platen and a second platen when the first platen is in contact with the second platen; opening the mold by separating the first and second platens; placing a second molding material at the first molding material while the first molding material remains with the first platen or the second platen; sealing a space between the first and second platens; removing a gas from the space while the space is sealed; and closing the mold while the space is sealed.

A mold for a production device for production of fiber-reinforced components by means of an injection process is provided. The mold has a mold surface to form a surface of the fiber-reinforced component, the mold surface having a first partial area and a second partial area and in which the mold has an injection area for injection of matrix material into fibrous material situated on the mold surface through the second partial area of the mold surface and evacuation area for evacuation of a mold volume bounded by the mold through the first partial area of the mold surface.

An apparatus or assembly for forming injection molded magnets in permanent magnet rotors or laminations for such rotors. The assembly includes a plurality of platens defining an axial boundary of a die cavity and a plurality of support shoes that are radially moveable between a closed position defining a radial boundary of the die cavity, and an open position creating a gap between the rotor core and the plurality of support shoes. The assembly has an injection system for filling at least one of the plurality of voids of the rotor core with a magnetic slurry, and a plurality of alignment magnets configured to magnetically align the magnetic slurry.

A glove for grooming an animal may include a first surface having a first nodule, a second surface having a second nodule and a third surface having substantially no nodules.

The invention relates to a method for producing a surge arrester, comprising the steps of: providing a module 1 comprising one or more varistor blocks 3 and two end armatures 5; introducing the module 1 into a mould 7 in order to form a housing 21; evacuating the mould 7 in a vacuum chamber 9; introducing liquid silicone 11 into the evacuated mould 7 in the vacuum chamber 9; baking the mould 7 in order to crosslink the silicone 11; and removing the surge arrester from the mould 7.

A resin product wherein a resin B has pillar structures or lamellar structures inside a resin A is molded by kneading the resin A and the resin B that serves as a base material in an injection molding machine while heating both of the resins to at least a temperature at which both of the resins are melted at least partially. The resin product is soaked in a solution having higher erosion capability with respect to the resin A than the resin B, thereby dissolving the resin B and forming an uneven structure on the surface. As a result, an uneven structure having various shapes, densities or depths which are precisely adjustable can be formed at low cost. And provided are a resin structure and a production method thereof that can maintain wettability control or optical property control of the molded article over a long period of time.
