Use of Blow Molding to Improve Weight, Cost, Assembly and Performance Characteristics of UnderHood Components
As the global automotive industry continues to strive for improved performance at lower costs, the use of blow-molded thermoplastics in underhood components offers a wide range of benefits, including: 1. Cost reduction 2. Weight reduction 3. Improved recyclability 4. Multi-functional part design opportunities 5. Reduction in number of parts and materials in the engine compartment 6. Greater temperature resistance to handle increasing powertrain temperatures 7. Easier assembly/disassembly for productivity improvements and cost savings in the manufacturing process 8. Reduced noise 9. Improved engine performance (up to 2 percent) Underhood applications where blow-molded technology can provide these advantages include turbo- charge ducts, air ducts, crankcase venting hoses, resonators, coolant reservoirs, and pipes and hoses for oil cooling, air conditioning and coolant systems. This technology is now used in the European automotive market and in Japan.
