Abstract:
An extrusion process for creating a roof ditch molding including forming a main body from a plastic material in a first stage extrusion, conveying the main body through a stacked array of die plates and into a first stage cooling tank, and communicating the main body from an outlet of the first stage cooling tank to a second stage extruder with crosshead die for applying a skim film bonding layer to the main body. Additional steps include applying a decorative layer over the skim bonding layer, communicating the main body to a third stage extruder with cross head die for applying wing portions in partially overlapping fashion along opposite side edges of the decorative layer and drawing the completed ditch molding through a second stage cooling tank prior to conducting one or more finishing operations.
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 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 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 filter box assembly for integrating into a bi-directional vent and air intake line associated with a vehicle fuel tank. The assembly includes an outer shell having an open inserting end and an opposite closed end. An inner communicable component is engageable within the open inserting end of the outer shell and collectively defines a plurality of continuous and reverse flow passageways extending between a plurality of inlet apertures defined upon a base surface of the inner component and a conduit attachment nipple extending from the inner component.
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.
Abstract:
An assembly for reshaping an elongated plasticized article includes a heated fixture upon which the elongated article is supported in adhering fashion to a contoured upper surface. Following heating, the article is transferred to a cooling fixture exhibiting a further contoured upper surface and, upon subsequent cooling, the article exhibits a final multi-dimensional extending profile matching the contoured upper surface of the cooling fixture. A further variation of the assembly includes an elongated and bowed track supporting a fixed jig at an end thereof. A slidable jig is traversable along the track and actuated by a ram in directions towards and away from the first jig. Upon a first length extending portion of the article being pre-secured to the slidable jig, a first forward feed direction of the article results in an end extending portion communicating within a multi-dimensional cavity establishing a contoured surface withing the fixed jig, subsequent rearward displacement of the slidable jig causes forcible reshaping of the elongated article as it is stretched and drawn against the contoured surface of the fixed jig.
Abstract:
A method for injection molding a pair of end muckets to a previously injection molded panel and prior to attaching a separately formed seal. The method includes the step of initially forming a vehicle panel from a first material in a closed cavity, following which a second stage injection molding process forms a pair of end muckets onto the panel. The separately formed seal exhibits an elongated profile and is inter-fitted between the end muckets, concurrent with being affixed to an extending surface of the panel, and to provide interface support between the seating ends of the seal and the adjoining vehicle fenders. Additional steps include injection molding a first plasticized materials into a closed cavity configuration established between assembled mold halves in order to initially mold the panel, following which a second plasticized material molds the end muckets along with additional wiper and windshield seals.
Abstract:
A baffle construction constructed of two or more individual sections, each exhibiting a two part/two shot injection molded material incorporating attachment details for establishing a structurally supporting framework mounting about the vehicle radiator. The baffle sections each include softer interconnecting hinges incorporating the attachment details which assist in creating the structurally self-supporting frame. The assembled baffle defines a four sided box-like structure mounted around a vehicle radiator for directing incoming air through a fascia opening and into a cooling module associated with the radiator.
Abstract:
A baffle construction constructed of a two part/two shot injection molded material having an integral and three sided body. Each of the sides including a panel section surrounded by a softer interconnecting hinge such that a plurality of living hinges are configured into the body and are located around and between each of a central panel and interconnected side panels. A secondary article is provided and includes an upper baffle assembled along with the lower baffle to define a four sided box-like structure around a vehicle radiator and in order to direct incoming air through a fascia opening and into a cooling module associated with the radiator.
