Battery housing

Electrical system battery box in the VW Pluto convinces as a complete package

Hostacom G3 R05 105555 Used for Battery Housing in VW Pluto

Light but Still Strong

Volkswagen's own ride sharing provider MOIA launched the electrically-driven VW Plutos in Hamburg in early 2019. The model used for this purpose is called MOIA 6+. The battery box for the electrical system is manufactured by H & H Gesellschaft für Engineering und Prototypenbau mbH, based in North Rhine-Westphalia, and made of the PP Compound Hostacom.

K.D. Feddersen Supported During Component Release

H & H Gesellschaft für Engineering und Prototypenbau mbH was commissioned by VW AG to design the tool and manufacture the series components. Due to problems with warpage problem in the manufacturing of the components for release by VW AG, Business Development Manager Christoph Gerling from the Hamburg-based plastics distributor K.D. Feddersen came into play and supported the further sampling for the component and mould approval.

The machine parameters were optimised so that the components meet the requirements of VW standard 44045 PP10 and they could obtain VW release.

The distributor also provided support for the preceding choice of material. The processor requested a PP with 30 % glass fibre reinforcement, which had to meet the required standard of VW AG.


“With Hostacom G3 R05 105555 from LyondellBasell, we recommended a PP compound which is easy-flowing, has excellent mechanical properties and also presents very low warpage,”

explains Gerling.

According to the distributor, the material is also recyclable and offers a very good price-performance ratio.

Requirements of VW standard 44045

According to VW standard 44045, the components on the surface and the interior must not have any imperfections or manufacturing defects such as flow lines, cavities or tears. Sink marks in the base area of ribs and reinforcements are only allowed if they do not impact the functionality and appearance of the component. Flawless installation must also be guaranteed. Under the PP10 notation, it is noted that the application area for highly thermally stressed parts has high requirements in terms of strength, stiffness and shape retention.

“We are very grateful for the support from K.D. Feddersen and for Mr Gerling's commitment to the implementation of the project and the solution to the delay problems,” says Udo Heckt, Project Manager at H&H Gesellschaft für Engineering und Prototypenbau mbH.

Apart from their application in the VW Pluto/MOIA 6+, the components will also be used for the VW E-Crafter. These vehicles are currently being built in various VW AG factories.
