What are carbon composite bellows springs?

The Carbon Composite Bellows Spring (CCBS) from MW Components is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace coil springs or metallic Belleville disc springs. A functional spring is made from several individual elements paired and joined to make a stack. The stack spring rate is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, and high-performance activities.

One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

Study says switching from aluminum to zinc alloys could improve longevity, sustainability of automotive parts

A new research effort reveals that switching from aluminum to zinc alloys in the production of automotive parts could greatly enhance their longevity and sustainability.

The study, conducted by Cranfield University's Sustainable Manufacturing Systems Center in England, compared three different alloys (Aluminum-A380, Magnesium-AZ91D, and Zinc-ZA8). Over recent years, aluminum alloys have been favored by the automotive manufacturing industry for their lightweight properties and lower cost.

The study, published in the International Journal of Sustainable Manufacturing, suggests that aluminum is frequently chosen ahead of other alloys because of a failure to fully factor in the sustainability of the end product into material considerations. When examining sustainability alongside traditional factors such as time, cost, and flexibility, Cranfield's research demonstrated that the zinc rather than the aluminum or magnesium alloys offered the better choice for automotive manufacturers.

The zinc alloy proved to be a more sustainable and higher-performing option, when considering measures such as the environmental impact caused by the extraction of the metal and the quality of the parts it produces. Despite the aluminum alloy being a lower-cost option, the study found that the zinc alloy also offered better value for money because the parts it creates are likely to have a much longer life than the other alloys.

Previous Cranfield research has demonstrated that the automotive industry's focus on increasingly lighter-weight cars to increase fuel efficiency, often through lightweight aluminum, may not actually be a more environmentally sustainable option.

"Aluminum has become the favored material of the automotive industry for its lightweight properties and comparatively low cost," said Professor Konstantinos Salonitis, Head of Sustainable Manufacturing Systems Center at Cranfield University. "However, our study, which looked in depth at sustainability, alongside traditional factors such as time, cost, and flexibilty, showed that actually a zinc alloy can be better value for money as well as being more sustainable."

Professor Mark Jolly, Director of Manufacturing at Cranfield University, added, "With the pressing climate crisis and consumers becoming ever more interested in the impact that the products they purchase have on the environment, manufacturers need to have a greater understanding of not just how they keep costs down but how they find the more sustainable option."
