Lighter, tougher crankshaft covers - for Volkswagen
The replacement of aluminum in this crankshaft cover – part of the MDB modular platform for diesel engines across its Audi, Seat, Škoda, and VW brands - has been achieved with a 45% reduction in weight and system costs.
And of course lower fuel consumption and carbon emissions: EcoPaXX is 70% bio-based and made principally from topical castor beans and is 100% carbon neutral from cradle to gate.
High performance crank shaft covers
But KACO, didn’t just choose EcoPaXX for its reduced weight and biobased qualities: The material is ideal for crankshaft covers thanks to very good mechanical properties at elevated temperatures, along with excellent toughness.
Improved processing in crank shaft covers
KACO uses a highly-energy efficient production cell to boost processing efficiency by molding the crank shaft cover, but also integrating two separate seals. The first is placed into the mold by a robot with EcoPaXX overmolded onto it; the second is then molded directly onto the part using a 2K process.
The results: crank shaft covers with zero material waste and even greater energy efficiency.
