Abstract:
A tri-extruded molding for mounting within a vehicle roof ditch. The tri-extruded molding is produced as an elongated trim defining component and is constructed of a rigid substrate material, a first UV graded thermoplastic elastomer applied over the exterior of the rigid substrate, with a second thermoplastic elastomer formed as a pair of laterally projecting wings along exterior and outwardly opposite edges of the rigid substrate and in communicating fashion with the jointly extruded edges of the first thermoplastic elastomer. A plurality of fasteners are seated within the track for mounting the molding to the vehicle roof ditch. A single production line process is disclosed for tri-extruding the three components into a roof ditch molding and includes a handling operation with opposing dies surfaces for compressing therebetween an initial straight length of extrusion for forming into a desired final shape.
Abstract:
A pair of top and bottom caps associated with a geothermal pipe. The top cap has a body with a first end face matching an open end configuration of the pipe, the top cap including first and second conduit portions. A bottom cap likewise includes a body with a first end face matching an opposite facing open end configuration of the pipe and an enclosed bottom portion for redirection of downward fluid flow through a first passageway communicating with the first conduit portion to upward fluid flow through a second passageway communicating with the second conduit portion. Additional features include each of the top and bottom caps having first and second arcuate shaped lobes around a cylindrical shaped central sleeve. Each of the top and bottom caps can further be constructed from an injection molding process.
Abstract:
A process and related assembly for creating an extrusion molded article with a chemically applied outer film. An extruded base material is formed during a first extrusion operation, following which a multi-layer film is bonded to the base material while the base material still at an above ambient temperature. The multi-layer film further includes successive layers of each of a polypropylene (PP), an adhesive, a polyethylene terephthalate (PET), a coating and s subsequent surface PET. The step of bonding of the film further occurs during an intermediate step between the first extrusion operation for forming the base material according to a given profile section and a subsequent extrusion operation for applying additional material along an edge of the film, the additional material including profile wings as required for a given design.
Abstract:
A method for producing a thermoplastic panel, including the steps of providing a rotary injection tool exhibiting a die cavity and featuring at least one lifter component within the cavity. The tool is positioned to orient the cavity in a first configuration during which a first shot injection molding of a doghouse is conducted onto a receiving location of the lifter component. The cavity is open and the tool rotated to reposition the cavity in a second configuration, following which a second shot injection molding operation is conducted for forming a skin of the panel in communication with the first shot doghouse clip. Following this, the mold is opened and the finished part removed.
Abstract:
A method for producing and installing a fastener, including the steps of forming an engaging portion having a projecting stem which is interiorly hollowed over at least an intermediate extending range, the stem including a solid end most extending portion, and forming a receiving portion having a surface, within which is configured an inner rim defined edge, a diameter of an aperture between said rim edge being less than a diameter of the stem. Additional steps include pressing the solid end most extending portion of the engaging portion through the inner rim edge of the receiving portion and aligning with the inner rim edge a location of the interiorly hollowed portion of the stem, causing inward collapsing of the aligned location by the rim edge to secure the engaging portion to the receiving portion.
Abstract:
A ventilation module for a vehicle having a housing including a flap hingedly secured along an inner edge to the housing to extend across its open interior. The flap includes side edges and an interconnecting outer edge which contact, in a closed flap condition, support locations configured along the housing to define its open interior. One or more fingers extend from at least one of the side and outer edges of the flap so that the fingers abut standoff locations of the housing located in proximity to the support locations. Upon a sufficient positive air pressure condition created within the passenger compartment which overcomes a holding force exerted by the fingers against said stand-offs, the flap is allowed to open in a controlled fashion to vent to the exterior the excess air pressure, until reclosing upon achieving an air equilibrium condition.

Abstract:
A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.
Abstract:
A closure assembly incorporating a crush barb which is molded into a recess cavity defining surface of a first piece. The crush barb is engaged by an inserting portion projecting from a second piece, the inserting portion being subsequently actuated into a collapsing and retention forming undercut with the crush barb in order to secure the pieces together. A variety of closure assemblies are provided with variations of inserting portions associated with the second piece, such including the use of an action/installation inducing tool for creating an undercut within the crush barb. Alternatively, the inserting portion may be configured with an over-center pivoting hinge which, upon being actuated, creates the crush barb undercut in order to engage the pieces together.
Abstract:
An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.
