Abstract:
A method and assembly for forming a multi-shot panel for a vehicle including the steps of providing a mold and forming therein a main body of the panel from a first rigid material, the step of forming the main body further including forming a multi-sided recess. The rigid material is transferred to a second reconfiguration of the mold for forming thereupon at least one second softer material. The panel is then transferred to a third reconfiguration of the mold for forming the heat deflecting shield. Alternative, a two shot injection molded panel can be removed from the mold and a previously formed heat deflecting shield can be attached along edges of the main body defining the multi-sided recess. In either variant, locking features are designed into the interface geometry between the heat deflecting shield and rigid main body.

Abstract:
An assembly and process for forming a two stage extrusion of an elongated marine dock from a plasticized material, such as including but act limited to extruding a first generally “L” shaped bracket from a first more rigid thermoplastic, following which a cross head die arrangement is utilized in order to extrude a secondary arcuate and flexible material in extending fashion from a lower side of the “L” bracket. The secondary/flexible elastomer is extracted in an open flexed position relative to the first extruded bracket, and further such that, following completion, can be flexed into a closed engagement with an upper perpendicularly extending side of the bracket.
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:
A retaining feature incorporated into a mounting surface of a plasticized article which is adapted to receive and retain a fastener prior to final assembly. The retaining feature exhibits an irregular and three dimensional shaped closed profile defined along an interior perimeter configured within the mounting surface and which establishes a degree of flex or bend upon insertion of the fastener with minimal loss of material. The insertion force can be any of lesser, equal to or greater than the extraction force, in combination with providing a rated side load breaking/shearing strength of the bolt from the material defined retaining feature.
Abstract:
The present invention discloses a fastener assembly having an engaging portion with a projecting stem which is interiorly hollowed over at least an intermediate extending range. The stem includes a solid end most extending portion. A receiving portion is provided with an inner rim defined edge, a diameter of an aperture between the rim edge being less than a diameter of an inserting portion of the stem. Upon forcible passage of the solid end of the fastener past the narrowed rim edge, an intermediate hollowed interior portion of the stem aligning with the narrowed rim edge and exhibiting a controlled collapse against said rim edge in order to anchor the portions together.
Abstract:
A process and assembly for producing a two stage injection molded article encapsulating an oriented glass strand mat substrate. A rotary press is incorporated into the injection mold assembly and which enables repetitive repositioning of an intermediate injection molded article into a second mold defining cavity for second stage molding and simultaneous with first stage molding of a subsequent glass strand composite positioned within the first mold cavity.

Abstract:
A method for forming a component exhibiting a sealed interior, including providing first and second mold halves, foaming 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.
