Faida muhimu zaidi ya alumini ni urahisi wa uundaji

Hakuna uhaba wa ushindani kati ya vifaa katika soko la usafirishaji. Swali sio nyenzo gani maalum ya kuchagua; kwa ujumla, siku zijazo ziko na miundo mchanganyiko ya nyenzo. Swali kuu ni nyenzo gani ni chaguo bora kwa programu maalum, kiufundi na kiuchumi; inategemea na aina ya gari, the envisaged design targets, the planned production volume, the existing manufacturing infrastructure and – not least – the available know how and experience.

The crucial step is an integrated design and engineering approach, taking into account the specific properties of the different aluminium alloys and qualities of the various aluminium semis and finished products. Intimate knowledge of the material characteristics, including crash behaviour, enables rapid product development based on computer aided design and engineering methods. Quantitative simulation of the related fabrication processes ensures efficient production of aluminium components and structural modules with consistently high quality.

The most important advantage of aluminium for the design of lightweight and cost-efficient structures is its ease of formability. Elaborate sheet panels can be efficiently formed using different methods ranging from high productivity stamping processes to low tooling cost technologies for low volume production. An interesting aspect compared to competing materials is the availability of extruded, open and closed profiles, with intricate shapes, in different wall thicknesses. Net-shaped and near net-shaped aluminium parts can be produced using forging and other massive forming techniques, but in particular by various casting processes. Depending on the applied method, cast aluminium parts can exhibit a wide range of sizes, shapes and properties. Extruded and subsequently machined profiles ,as well as high quality, thin-walled pressure die cast aluminium components, are not only beneficial for load-carrying and/or stiffening functions, but can be applied simultaneously as joining elements. Their proper use enables the development of new, innovative structural design solutions and – as a result – significant weight and cost savings by parts integration and the incorporation of additional functions.
