Apparatus for Molding Hollow Workpieces
An apparatus and process for molding workpieces usable for consumer products. The workpieces may be injection molded with a cavity formed by a core pin and have an undercut, such as internal threads, in the cavity. The apparatus has a drive system with a stripper plate mounted for alternatingly forward and retracting axial movement. The stripper plate is axially driven and drives a stripper sleeve barrel cam and a core pin base barrel cam, each having respective cam followers. The respective motions of the cam followers are superimposed on a stripper sleeve insert, which drives a core pin sleeve. The core pin sleeve is subjected to responsive three dimensional motion, allowing an internally threaded workpiece to be unscrewed from the core pin sleeve. The system does not require separate drives for the core pin sleeve, a single stripper plate drive being sufficient and further allows each mold cavity/core pin combination in a mold half to be unique.
METHOD AND APPARATUS FOR INJECTION MOULDING OF PLASTIC MATERIALS
Method and apparatus for injection moulding of plastic materials using at least one nozzle with an obturator including a stem having a through hole and displaceable transversely with respect to the nozzle between a closing position and an opening position wherein the through hole opens communication between the nozzle and the flow path towards the mould. When the obturator is arranged in the closing position following injection, the through hole remains in communication with the cavity of the mould and a residual core made of plastic material present in the through hole remains joined to a residual core made of plastic material in the flow path and it is removed together with it.
SYSTEM AND METHOD FOR MAKING SOFT PROJECTILES
The present invention discloses a system and method for making soft projectiles for use with toy and recreational firearms, the system and method comprising of a mold and a projectile material, the mold comprising of a first plate with one or more protrusions and a second plate with one or more cavities, the second plate mated with the first plate to form one or more soft projectiles.
FORMING DEVICE AND FORMING METHOD
A forming device that forms a 3D object includes a head section including a plurality of nozzle rows, and a scanning driving section that causes the head section to carry out a scanning operation; where the head section includes a first nozzle row group, a second nozzle row group, and a support nozzle row group; in an operation of at least one of the forming modes, the forming device forms at least one part of the 3D object using the first nozzle row group and the second nozzle row group and forms a support layer in a periphery of the 3D object; and when a maximum value of a material dischargeable in unit time in one scanning operation is defined as a material discharging ability, the material discharging ability of the support nozzle row group is greater than the material discharging ability of the first nozzle row group.
Sealed cable passage for an exhaust-gas sensor
A cable passage for sealing and for electrically contacting an exhaust-gas sensor includes: a protective sleeve; and at least one connecting cable which is run out of the protective sleeve on at least one front side of the protective sleeve. At least one cross section of the space existing between the protective sleeve and the at least one connecting cable is filled with a thermoplastically workable fluoropolymer-containing material.
FUEL PUMP MODULE FOR IMPROVING RADIANT HEAT AND METHOD FOR MANUFACTURING THE SAME
Provided are a fuel pump module for improving radiant heat and a method for manufacturing the same, in which when heat generating components included in the fuel pump module are fixed by a potting process of injecting a liquefied resin, a guide is installed first, the liquefied resin is injected, and a heat radiating plate is inserted into the guide to increase a size of the heat radiating plate, thereby increasing heat radiating capability.
ELECTRO-PHOTOGRAPHIC 3-D PRINTING USING DISSOLVABLE PAPER
In 3-D printing a platen moves toward an intermediate transfer belt (ITB) to have a sheet positioned on the platen contact the ITB to electrostatically transfer a layer of different materials to the sheet, and then the platen moves to a heater to join the layer to the sheet. This processing is repeated to have the sheet repeatedly contact the ITB (with intervening heating at the heater) to successively form layers of the materials on the sheet. The sheet having the layers thereon moves to a rinsing station, where a liquid is applied to dissolve the sheet and leave a freestanding stack of the layers. The freestanding stack is fed to a platform to successively form a 3-D structure of freestanding stacks of the layers. Light and/or heat are applied to the 3-D structure to bond the freestanding stacks to one another on the platform.
MICRONEEDLE ARRAY
To provide a microneedle array which includes a sheet and needles, improves transfer of a medicament into the blood, and is capable of achieving high drug efficacy.
Provided is a microneedle array including: a sheet; and a plurality of needles present on the upper surface of the sheet, in which the needles contain a water-soluble polymer and a medicament, the sheet contains a water-soluble polymer, and the administration is performed such that 20 μm≦L2≦L−L1 is satisfied, here, L represents the length of a needle, L1 represents the length of a needle tip region, which contains 90% of the total medicament in the microneedle array, from the needle tip, L2 represents the average remaining length of the needle after administration using the microneedle array, and the unit of L, L1, and L2 is μm.
METHOD AND APPARATUS FOR APPLYING A LAYER HAVING A RELIEF ON A FLAT FACE OF A SUBSTRATE
A method for applying a layer having a relief on a substrate includes, steps of securing the substrate, applying a layer of a curable liquid on the substrate, bringing a mould having a relief being the negative of the relief to be provided on the substrate, into contact with a part of the upper surface of the liquid layer, curing the liquid layer while the mould is in contact with the liquid and separating the mould from the substrate. Initially the mould is brought into contact with the liquid in a bent position while the substrate is kept flat and subsequently the mould is brought into contact over an increasing surface area keeping the mould in a bent position until the complete liquid layer is in contact with the mould.
Hybrid organic-inorganic micromirror device and method of making a hybrid microdevice
A hybrid organic-inorganic micromirror device includes a micromirror comprising an inorganic material positioned above an elastomeric substrate. The micromirror is supported on an underside thereof by a conductive elastomeric support protruding from the elastomeric substrate. The conductive elastomeric support may function as a universal joint and is rendered electrically conductive by an electrically conductive coating thereon. A plurality of electrodes are disposed on the elastomeric substrate under the micromirror. The electrodes are spaced apart from each other and from the micromirror and are arranged around the conductive elastomeric support. Each electrode comprises an inorganic material and is in electrical contact with an elastomeric contact region protruding from the elastomeric substrate. When a voltage bias is applied between the micromirror and one or more of the electrodes, the micromirror is electrostatically actuated to move in a predetermined direction.
