Abstract:
The present disclosure provides a molding element for a mold used for manufacturing a tread of a tire having a plurality of contacting element, a plurality of grooves and a connecting member connecting two side faces of adjacent contacting elements, the molding element having a molding surface and a rib for forming the groove between adjacent contacting elements, at least two rib side faces, the rib having a notching portion, the guiding member having a guiding slit extending from one of the two opposite side faces to the other of the two opposite side faces through the guiding member and radially from the top face, at least one of faces of the notching portion is provided with a means for keeping the guiding member in place in the notching portion.
Abstract:
Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a mask adapted to increase depth of focus. The method of manufacturing the implant can include positioning the mask with an aperture on a protruding pin of a positioning mold portion. The protruding pin can be configured to center the mask in the intraocular lens.
Abstract:
The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.
Abstract:
A bottom chase and a top chase of a molding system form a cavity to house a molding carrier and one or more devices. The molding carrier is placed in a desired location defined by a guiding component. The guiding component may be entirely within the cavity, or extend above a surface of the bottom chase and extend over a contacting edge of the top chase and the bottom chase, so that there is a gap between the edge of the top chase and the edge of the molding carrier which are filled by molding materials to cover the edge of the molding carrier. Releasing components may be associated with the top chase and/or the bottom chase, which may be a plurality of tape roller with a releasing film, or a plurality of vacuum holes within the bottom chase, or a plurality of bottom pins with the bottom chase.
Abstract:
A blowing pad, a fabrication method of the blowing pad, and a blowing system using the blowing pad are provided. The blowing pad includes a main foam formed of a foamed porous synthetic resin, and a duct embedded in the main foam, wherein the main foam includes an air inlet to which an air inlet tube is inserted and a plurality of vent holes, each of which is connected to the duct, wherein the duct is formed of any one of natural rubber, synthetic rubber, and non-porous plastic, wherein the air inlet tube is connected to an external blowing pipe.
Abstract:
A developing blade 10 is insert molded by forming a rib portion 13 which projects from an end portion in the longitudinal direction of a blade body 12 in the transverse direction of the blade body 12, opposite to the contact surface 12a side of the blade body 12, on the blade body 12 in contact with the developing roll of the developing blade 10 and forming the gate 21G of a metal mold 20 in which a metal plate 11 as an insert member has been installed only in a cavity 21b corresponding to the above rib portion 13. Therefore, a developing blade 10 without burrs and recesses on its contact surface with the developing roll or without welds can be easily manufactured.
Abstract:
A method and apparatus for forming sealing and/or retaining elements on a wide variety of fastening devices is provided. The fasteners are conveyed on fastener nests each having a chamber, a fastener lock and a fastener release that are moveable relative to each other. The fasteners then have material applied to them which is cured while the fasteners are in the nests on the conveyor. The fasteners with the sealing and/or retaining element formed thereon are then removed therefrom. A novel fixture for holding fasteners to be processed and an element sealing device having a fastener with a resilient sealing element adhered to a portion thereof with a depression formed therein in close proximity to a portion of the fastener is also provided.

Abstract:
A molded article includes a rotationally-molded body of polymer material, formed in a mold, with an elongate reinforcing member, having an end, substantially encased within the body of polymer material during molding thereof. A slip zone, defining a void in the body of polymer material, is formed around the end of the reinforcing member, such that post-molding shrinkage of the polymer material imposes substantially no stress on the end of the reinforcing member.
