When turning the key in the ignition of your car you immediately put heavy loads on more than 200 fasteners located in the engine. When driving out of the garage an additional 2300 screws and nuts in the axle and chassis are affected. The automotive industry is Nedschroef’s major customer, and as such the major influence for the development of our products.
With the signing of the Kyoto agreement, development trends within the automotive industry changed drastically. Since the day the car was first invented, features like horse-power and fast acceleration have been key selling arguments. Picking up any car magazine printed after 2008 will show that features like low emissions and modest fuel consumption are now in focus instead. Today, Image is measured in emissions performance, and the majority of the major car producing companies are concentrating their research on emission control. As the traditional combustion engine is likely to remain the volume engine on the market for the foreseeable future, emission reduction will mainly focus on reducing fuel consumption and making the engine cleaner. One of the key parameters identified to achieve emission reduction is weight reduction.
Weight reduction is achieved mainly via smart and efficient choice of the correct material for the correct application. A general change-over from steel and cast iron to aluminum and magnesium has been ongoing on a broad scale since the beginning of 2000 and today engine blocks and chassis components made from aluminum are common in the market.
- Development of ultra high tensile strength material to contribute to the design changes which are needed to meet future emission standards.
- Development of cost efficient temperature resistant material and products.
- Development of thermo-mechanical processes to achieve optimal mechanical properties of steel & aluminium products.
Reducing the overall weight in constructions is leading to different technologies for fasteners as:
- weight reduction
- less fuel consumption
- less CO² emission
