Abstract:
A process for manufacturing a wafer carrier including injection molding a wafer support structure. The wafer support structure has a plurality of wafer support shelves extending therefrom. The process further includes molding a wafer contact portion on each of the wafer support shelves. The wafer contact portions bond with the wafer support shelves without mechanical fasteners between the wafer contact portions and the wafer support shelves. The process also includes overmolding a shell over the wafer support structure to form the wafer carrier. The shell bonds with the wafer support structure without mechanical fasteners between the shell and the wafer support structure. The wafer contact portions define a plurality of slots for holding a plurality of wafers.
Abstract:
A problem in the manufacture of filters using tubular membrane bundles is keeping potting material from flowing into the openings at the ends of the tubes. A preferred embodiment of a method for manufacturing a tubular membrane filter employs a non-contact heat source such as radiant heating to melt the tips of the tubular membranes. This prevents the migration of potting material into the tubes when the potting material is flowed into the ends of tube bundles during the manufacturing process for a filter.
Abstract:
A composite wafer carrier according to an embodiment of the present invention comprises an operative portion formed of a first thermoplastic material and a support portion formed of a second different thermoplastic material. One of the operative portion and support portion is overmolded onto the other to form a gapless hermitic interface that securely bonds the portions together. The operative portion may be a transparent window, a portion of a latching mechanism or a wafer contact portion. Preferred embodiments of the invention include wafer carriers with said features, process carriers with said features and a process for manufacturing wafer carriers with said features.
Abstract:
A mould is described for moulding an elastomeric glazing profile in situ on a single major face of a sheet of glazing material, e.g. a glass sheet. The mould comprises a first mould segment and at least one further mould segment which are relatively movable into intimate contact, so that they define, together with the sheet, a mould cavity for moulding the profile on the single major face. The profile has a show face, (i.e. one which is visible in use), and the portion of the mould cavity that moulds the show face is entirely formed by a single mould segment to avoid mould lines on the show face. Also described are a corresponding moulding method and the glazing product thereby obtained, which may be used as a vehicle window.
Abstract:
The invention is related to a device (1) and to a method for the injection molding of articles (25) with several plastic material components. This device (1) comprises a first half mold arranged as fixed (3), a second half-mold (6) arranged as movable relative to the first half-mold (3) for the purpose of opening and closing the device (1). In addition, the device (1) comprises at least two further half-molds (10, 11), which are arranged as jointly movable relative to the first and second half-molds (3, 6), and which in the closing position of the device (1) are situated between the first and the second half-molds (3, 6), so that in two parting planes (32, 33), namely in a first and in a second parting plane (32, 33), cavities (20, 21) are formed. The two further half-molds (10, 11) arranged as jointly movable comprise means (22), which in the case of an opened device (1) serve for the transportation of the article (25) out of a first cavity (21.1) into a second cavity (21.2) in such a manner, that the article (25) is capable of being injection molded around with a further material component in the second cavity (21.2).
Abstract:
A window module has a fixed-pane window which is encapsulated by a molded trim piece having an integral portion which extends around an adjacent movable window opening. The integral trim piece is formed of EPDM. The window module is constructed by placing a window pane, a division post and an end of an extruded continuous EPDM trim strip and a header trim strip into a mold into which the EPDM polymer is injected to integrate and encapsulate the inserts.
Abstract:
A vent apparatus includes a tank mount made of a weldable plastics material and a fuel systems component such as a valve assembly. The valve assembly includes a valve housing made of a non-weldable plastics material and a valve movable in a valve chamber formed in the valve housing to open and close an aperture leading to a venting outlet. The tank mount supports the valve housing in a position in a mounting aperture formed in a fuel tank. The valve housing is made by injecting non-weldable plastics material into a mold containing the pre-molded tank mount.
Abstract:
A molding includes an attaching portion to be bonded to an interior side of a peripheral edge of a glass plate and an elastic portion capable of being in close contact with a window opening. The molding 11 is made of thermoplastic resin and has an electrically conductive member insert-molded therein, the electrically conductive member extending substantially parallel to a surface of the glass plate and generating heat by bringing an eddy current generator near thereto. The eddy current generator is brought near a surface of the transparent plate to generate heat in the electrically conductive member, thereby softening or melting the molding, and an external force is applied to the transparent plate to disassemble the transparent plate from the window opening of an automobile.
Abstract:
A device for foaming around a transparent pane for a motor vehicle roof, including a top tool having a top shaping structure mounted on a top carrier, and a bottom tool having a bottom shaping structure mounted on a bottom carrier. The shaping structures act as a boundary for the area to be peripherally foamed, and the top tool and the bottom tool are made adjustable relative to one another for inserting or removing the pane and the interchangeable bottom shaping structure. The top shaping structure is also interchangeable to enable matching of the peripheral foaming device to different size and shape panes to be peripherally foamed.
Abstract:
Methods for manufacturing panel units may include applying a cover tape to a surface of a panel in such a way as to substantially extend along a periphery of the panel. An extrusion molding die may be moved relative to the panel in such a way that the extrusion molding die moves along the periphery of the panel while at least partially contacting the cover tape applied to the panel. At the same time, a molten molding material may be extruded from the extrusion molding die, thereby integrally forming a molded article on the periphery of the panel. The cover tape may be then removed from the surface of the panel in order to produce a panel unit having the molded article disposed along the periphery of the panel.
