Plastics/metal hybrid technology saves weight in airbag assemblies with integrated lead frames

A hybrid plastics/metal airbag housing with integrated lead frame, co-developed and produced by MCAM Plastics for an automotive steering wheel airbag assembly, reduces weight, packing space and costs.

Production is carried out fully automatically to provide high levels of quality and safety in the zero-defect environment of automotive passive safety. The assembly is being fitted on vehicles produced around the world.

The integrated lead frame activates the horn when the driver presses the airbag cover in the center of the steering wheel, completing an electric circuit. The module is a safety-critical component; therefor design and manufacturing requirements are very demanding. It is produced by injection molding a 40% glass fiber reinforced polyamide over a pre-coated stamped steel insert.
 
MCAM Plastics worked with its partners along the supply chain on the development of a fully automated production/assembly/quality control process.

The airbag housing contains the airbag itself as well as the gas generator, with its main function being to direct the airbag during deployment, while maintaining the integrity of the housing. The design of the housing, as well as the polymer processing technology used to make it, is of prime importance to this. The hybrid structure is created by combining the plastics housing with the metal lead frame. The overmolding process is carried out fully automatically in a purpose-built manufacturing cell at the main plant in Tielt, Belgium. Six-axis robots position the lead frames precisely into the molds. The reinforced polyamide is injected around it. After molding, the housing is removed from the mold and placed in a quality control station that carries out a 100% quality check. Once the part’s quality is assured, it is positioned on a conveyer belt that takes it to additional downstream assembly operations.

The plastic/metal hybrid molding has replaced an assembly of cables on a full steel housing that was more complicated and costly to produce, heavier, and which took up more packing space. It was first introduced on cars in 2012. The success of the design has led to introduction on many other vehicles. MCAM Plastics ships these parts from its plant in Tielt Belgium to locations in Europe, USA, Brazil and India for integration into complete airbag assemblies.

The hybrid integrated lead frame fits with the trend in the automobile industry to reduce weight  and also space. This to allow room for the growing range of increasingly sophisticated safety- and entertainment-related devices, especially in and around the steering wheel and of course, costs.
