Injection molding a blow moldable grade of HDPE to maintain compatibility with welding to fuel tank surface.
Weight Savings: None
Cost Savings: None
Most Innovative Feature: Mechanically locked non-bonding polymers using rotary 2-shot process. This part is comprised of a HDPE weld foot, and an acetal barb fastener that is used to secure fuel system components within a fuel tank.
Other Innovative Features: Injection molding a blow moldable grade of HDPE to maintain compatibility with welding to fuel tank surface.
Forming Process: Rotary platen 2-shot injection molding.
First time process used?: Yes
Previous Process Used: Traditional non 2-shot molding and insert molding.
Tooling Innovations: Developed a single mold to produce the product from two mechanically locked plastics.
New Material Developments: None
Weight Savings: N/A
Direct Cost Savings: N/A
Indirect Cost Savings: N/A
Direct Consumer Benefit: N/A
Translates to other Vehicles?: Yes, It can be applied to any other vehicle.
Safety Benefits: This component is part of a complete system that represents the next generation of fuel tanks.
Environmental Benefits: The use of this component allows for fuel tank to maintain increased level of hydrocarbon barrier resulting in meeting higher level governmental regulations (LEV II).
Additional Info: The fuel tank industry remains challenged to improve plastic fuel tanks to higher governmental emission regulations. The use of plastics continues to face competition from the steel industry and other technologies to meet these regulations. This product helps blow molded fuel tanks to meet LEVII requirements.
