INDUSTRY NEWS/ਸ਼業新聞


should be possible with strong cooperation, but it will be simpler with common standards and more reliability. Due to the increased demand of cast parts of the


automotive industry, the global diecasting industry is doing well. For all car segments, the proportion of aluminum and magnesium is increasing, while trucks, buses and trains seem to be planning for more lightweight parts in the future. OEMs are investing in their plants, looking for more supplier capacities, and asking for higher requirements and more flexibility to achieve new designs which contain more aluminum and magnesium usage. Today´s limit of CO2 emission will drop from 123g/100km to 95g/100km in 2020, and to avoid strict penalties, the OEMs will have to meet the severe targets. Te history of the proportion of lightweight compo-


nents during the last 45 years shows exactly the engineer- ing reactions due to relevant factors. During the petrol crisis in the 70s the OEMs started to develop smaller and more efficient, aerodynamic cars. Te light metal share was about 30 kg in a medium car, mainly in wheels, smaller engines and gear components. Aluminum and magnesium usage increased dur- ing the 1980s up to 60 kg per car as a result of green economy duties, so cylinder heads were made of alumin- ium. Even more development and requirements in the 1990s, when passenger´s safety and comfort was a must, like ABS, all-wheel drive or air condition, which means more weight compensated by light weight parts up to 90 kg per car. Today the average aluminum, magnesium weight is about 150 kg per car in a medium class car, but the weight is still about 1 ton like in the 1980s. Te forthcoming CO2 emission limit will motivate


the OEMs to accomplish the legal requirements and there is a potential of more than 220 kg par car in light- weight constructions like not only wheels, engine parts and transmission, but also suspension components, body and white structural parts and seat and door frames. Frankly speaking, the OEMs are interested in the


most efficient processes and the best results and trend setting technologies. HPDC is in an excellent posi- tion, but they have to follow for instance the engine evolution from diesel gasoline engines to hybrid and full electric vehicles, with different engines and dif- ferent lightweight parts. Furthermore, plastic parts, carbon fiber elements and other aluminium technologies beside HPDC should be followed with advisable respect. Te International Forum was an excellent step in the


right direction to be prepared and was advantageous for the entire diecasting industry. Te exchange of ideas, requirements and future mile-


stones supports all participants from the production to the supply chain.■
