A two-piece part may include a first portion defining at least one through hole and a second portion may be cast such that the second portion extends through the through hole thereby mechanically interlocking the first portion and the second portion together.

A vehicle body assembly includes a first body wholly or partly made of a first polymeric material. The first polymeric material includes a polycarbonate and has a 60-degree gloss that is equal to or greater than 80 gloss units. The first body defines an outermost surface of the vehicle body assembly. The first body may be an exterior trim component, such as a grille portion, and may have a black color. The vehicle body assembly further includes a second body coupled (e.g., chemically bonded) to the first body. The second body may be a support body configured to support the exterior trim component and is wholly or partly made of a second polymeric material. The second polymeric material is different from the first polymeric material, and the outermost surface of the first body faces away from the second body.

Low stress attachment for high gloss weatherable polycarbonate decorative applications

A stabilizer guide for guiding a stabilizer, having a material characteristic of fraying, through an extrusion die without fraying and melting the stabilizer during the extrusion of a thermoplastic body molding of a motor vehicle. The stabilizer guide is made up of two halves that join to form a parting line and a slot by which to guide the stabilizer through the extrusion die. The slot extends along the entire length of the stabilizer guide and is located in a different plane than the parting line of the stabilizer guide. By having the slot in a different plane than the parting line, the stabilizer is prohibited from wandering into the parting line. This prevents the stabilizer from fraying and shredding and causing the slot to be obstructed by pieces of the stabilizer. Obstruction of the slot hampers the stabilizer from being guided through the stabilizer guide.

Extrusion die stabilizer guide and method of extrusion

A method of using a plastic extruder equipped with an extrusion die and a gloss controlling auxiliary die to produce an extrudate of polymeric material having controlled gloss appearance comprising the steps of first extruding an extrudate of polymeric material through the extrusion die and then passing the extrudate immediately after exiting from the extrusion die through a gloss controlling auxiliary die which is kept at a temperature either higher or lower than the temperature of the extrusion die.
