Thread-forming screw for high-performance and bioplastics.

If we look globally at developments in the automotive industry, we can see that the weight of new passenger cars and light commercial vehicles in Europe has risen constantly in recent years from approx. 1,268 kg in the year 2000 to 1,360 kg in 2010 and to approx. 1,420 kg in 2020. The trend toward more hybrid and electric vehicles is likely to intensify this development because an electric vehicle weighs on average 300 kg more than a vehicle with a conventional engine due to the weight of the battery alone.

When joining plastics, light metals or steel together, press-fit screws are often used. Thanks to a new triangular-shaped quick fastening system, with locking threads on a triangular shaft, very high pull-out forces can now be achieved and clamping parts fixed rapidly.Thanks to a new triangular-shaped quick fastening system, with locking threads on a triangular shaft, very high pull-out forces can now be achieved and clamping parts fixed rapidly.

High production capacity utilization is a must for the industrial sector in order to remain profitable in the future.

When joining lightweight metals, the focus is on the installation space available and on optimising performance and cost, as well as on the reliability of the fastening. And in light of that, an important point is the optimisation of the fastening’s load capacity.

Bioplastics are increasingly used in industrial products like automotive, electronics, and building components. However, threaded connections in biopolymers require adapted screws for consistent fastening quality.

As many companies are now doing, ARNOLD Umformtechnik regularly draws up greenhouse gas balance sheets to keep a constant eye on the potential for climate protection measures across the whole company. Collecting data for a meaningful climate balance sheet is costly and complex, but it pays off: production at the manufacturer of high-quality fastening systems and precision parts has been classed as climate-neutral since 2021.
