Abstract…
A new generation of reinforced engineering thermoplastics is fast becoming the standard for Tier 1 automotive applications - from engines to airbags.

The newest application is a unique hybrid concept for oil pans - and oil sumps -that will enable the industry to reduce weight by up to 30-40% and system costs by up to 20% - whilst at least matching the overall performance of metals, as well as enabling a reduced carbon footprint.

This latest innovation is possible thanks to Akulon®, a revolutionary PA6 thermoplastic that not only outperforms many metals but also enjoys many superior qualities to PA66 (improved processing, long-term heat resistance and improved welding properties).

The coming years will see the introduction of a hybrid oil pan integrated with the structurally loaded bed plate that carries loads from the transmission system. Not only the pan will be made entirely from PA6, but also the main part of the bed plate.

The load of the transmission box will be carried by a small aluminium bracket. T the two plastic parts, meaning the pan and two-thirds of the bed plate, are joined together using different kind of welding techniques (vibration, hot air and infra red welding). These two weldedjoined parts together form the oil container.

It's been a huge engineering effort, totalling three years of extensive (and expensive) research and development, redesign and now the long-awaited moment of success.
