METHOD FOR PRODUCING A COMPOSITE SEALING ELEMENT
20170355113 · 2017-12-14 ·

A method for producing a composite sealing element, in particular for forming a seal at a retractable pane of a vehicle window, wherein the composite sealing element is produced from at least one extruded element portion and at least one element part formed by injection molding in a mold cavity of a mold, with the element part being molded onto an end face, bounding the mold cavity, of the extruded portion. A change in the dimensions of the composite sealing element as a result of the length of the extruded element portion differing from the nominal value is counteracted by changing the arrangement of the end face of the extruded element portion with respect to the mold cavity.

TOOL FOR OVER-MOULDING AND/OR BACK-MOULDING A CURVED GLASS BODY, AND METHOD FOR OVER-MOULDING AND/OR BACK-MOULDING A CURVED GLASS BODY

A tool for overmoulding and/or backmoulding a curved glass body is proposed, the tool having a first surface for supporting the curved glass body. The tool comprises a plurality of pins, the pins each having a first end face at a first end of the pins, and at least one section of the first surface being formed by the first end faces of the pins. The pins are mounted to be displaceable in their longitudinal direction so that at least the section of the first surface can be adapted to a contour of the curved glass body.

Injection molding apparatus for inserting atypical stiffener

An injection molding apparatus for inserting atypical stiffener including an upper mold provided with an upper core and an under mold provided with an under core for manufacturing an injection molding product by receiving synthetic resin melt and curing in a state in which an atypical stiffener whose size is not constant is inserted, may include elastic clampers supported by the under mold, embedded in the under core, interlocked with the size of the atypical stiffener, and elastically pressurizing both sides to hold the atypical stiffener to be inserted into a correct position between the upper core and the under core by the atypical stiffener when the synthetic resin melt is introduced.

Apparatus and method for injection molding encapsulation

An injection mold for encapsulating a substrate comprises a lower mold component and an upper mold component adapted to form an encapsulation mold at an edge of the substrate when the upper mold component engages the lower mold component. The lower mold component comprises a substrate support and wherein the upper mold component comprises a recess. The injection mold includes a tiltable insert sized and shaped to slide within the recess to form a seal for the encapsulation mold, the insert having a substrate-contacting surface defining an area of the substrate contacted by the insert. The injection mold includes a plurality of pressure-exerting actuators connected to the tiltable insert and each being configured to independently apply pressure on the substrate via the insert, wherein the plurality of pressure-exerting actuators are adapted to equilibrate a total predetermined pressure exerted by the insert substantially evenly across the area of the substrate-contacting surface.

Forming Mold

The invention discloses a forming mold including a stationary half and a moving half matched with the fixed one. The stationary half including a stationary plate, a stationary base fixed on the stationary plate, and a slider and a movable traverse bar which are disposed on the stationary base. The slider and the movable traverse bar are movable on the stationary base in a vertical direction. The moving half is movable relative to the fixed one in a horizontal direction. A space for in-mold forming is created between the two mold modules. By moving the slider and the movable traverse bar in the vertical direction, the forming mold can adapt to different workpieces. The flexibility of the forming mold can be increased, and the cost can be saved by way of not having to change to another sized of forming mold.
