INTEGRATED FLOOR BEDLINER DIVIDER

• OEM Make & Model:  2017 General Motors Co.   Chevrolet Silverado pickup

• Tier Supplier / Processor:  Penda Corp. / Penda/Durakon   

• Material Supplier / Toolmaker:  A. Schulman / Penda Corp. 

• Material / Process:  Polytrope TPP1026EU TPO / twin sheet thermoforming

 

Description: This first time twin sheet thermoformed bedliner divider is integrated into the bedliner as one piece. A $275 cost avoidance resulted by not having to manufacture a separate floor divider part.  The divider incorporates a molded in locking feature to secure the divider into the truck wall when it is raised.  It eliminates the need for a cargo net or separate divider allowing the customer to put smaller items in the bed without having the items move and slide around while the vehicle is in motion. Dual textures are achieved on both sides of the part and the design can be applied to different vehicle models and brands via an insert for different logos.

 

GRAND AWARD & CATEGORY:    Body Exterior

STRUCTURAL AGS WITH INTEGRATED LOOSE LAYER CONSTRUCTION

• OEM Make & Model:  2018 Ford Motor Co. Ford Expedition luxury sport-utility vehicle (SUV)

• Tier Supplier / Processor:  Magna Plastcoat / Magna Plastcoat

• Material Supplier / Toolmaker: Celanese / Integrity Tool

• Material / Process: Celstran 40-20 PP GF/ injection molding

 

Description:  This, possibly the largest 2-shot AGS in production today, was designed with an integrated locating and attaching system for consistent fit between the grille and headlamps, eliminating the need for FEM assembly, dunnage and shipping. In addition to reducing variable and piece costs by an estimated $5 with an entirely thermoplastic solution, the enhanced design achieved $16 internal assembly cost reduction per vehicle and eliminated around $45 auxiliary costs by negating the need for a FEM.  As a result, Ford avoided an estimated $2 million in dunnage, assembly plant line and handling costs. Improved parts consolidation also phased out the need for four separate fasteners and associated labor.  Using LFRT technology to develop a structure with polypropylene offset an estimated 3 lbs. of weight over alternative metal and nylon hybrid designs considered. An equivalent steel structure would weigh 18 lbs. more than the LFRT design, which delivers the required durability.
