Henkel and 4JET have joined hands to introduce a new process for producing silent tyres for electric vehicles (EVs). In the new LASER-FIT process, a tailor-made acoustic foam is produced directly inside the tyre from liquid starting materials, at the end of the tyre line.

The current process of making silent tyres carries along with it a number of overheads, namely a second logistics line to transport the lightweight but high-volume foam to the ‘tyre wedding’ at the end of the production line, multiple stages of intermediate storage for the foam and several additional manual or semi-automatic steps for logistics, cutting, adding adhesives and foam insertion into the tyre. Also, the appropriate foam must be provided ‘just-in-sequence’. This process increases the cost of production by up to 25 percent and leaves us with significant volumes of waste generated from the off cuts of the foam pieces.

The new direct-foam-to-tyre process aims to eliminate all these hassles. With the LASER-FIT process, you don’t need to worry about the ‘just-in-sequence’ complexity, time-consuming logistics and manual process steps. Moreover, it also provides greater freedom in adapting the foam’s geometry and volume to the tyre type, thereby reducing waste generation. This process is made possible using patented foam activation process using a laser after the application of foam. The foam forms an air-impermeable skin on the surface, which minimises the penetration of sound into the open-pored acoustic foam and prevents sound absorption.

The process concept was presented at TireTech in Hannover this March and the complete solution will be presented at RubberTech24 in Shanghai this month.

Dr Rainer Schönfeld, Global Market Strategy Head in Henkel`s Automotive Component business unit, explains, “Our new to market Loctite LASER-FIT acoustic foam achieves its sound absorption effect through a large inner surface and a pore design specifically tailored for tyre noise suppression. Without 4JET`s laser activation process, which precisely removes the foam skin, the majority of sound waves would be reflected off the foam surface instead of being absorbed. This great idea is a prime example of the innovative strength of German SMEs, which continue to be the engine of our economy!”

George Kazantzis, Global Head of Henkel`s Automotive Components business unit, adds: “This revolutionary direct-foam-to-tyre technology represents our joint commitment to innovation and sustainability. By eliminating the transportation of pre-fabricated foam and reducing cutting waste, we will enable our customers to lower their carbon footprint.”

Dr Armin Kraus, Co-CEO of the 4JET Group, stated: “In Henkel, we have found the ideal development partner for this innovation. Henkel combines expertise in the development of technically sophisticated PU foams with their mechanical application like few companies in the world. At the same time, Henkel has the necessary industry knowledge in the automotive industry as well as the global footprint required to reliably supply the tyre industry worldwide with products of consistently high quality. We witnessed this. What impressed us most was the passion and speed with which Henkel works. From the idea to the finished application in record time: we will be presenting our joint complete solution at RubberTech24 in Shanghai this month.”

NASA has launched a three-phase competition offering USD 155,000 in prizes to develop next-generation wheels for lunar rovers, as the US space agency prepares for sustained exploration missions to the Moon’s surface.

The “Rock and Roll with NASA Challenge” seeks lightweight, durable wheel designs capable of traversing the Moon’s harsh terrain of razor-sharp regolith whilst maintaining performance in extreme temperature variations and carrying substantial cargo loads at higher speeds.

The competition addresses critical mobility challenges facing future lunar missions, where traditional rover wheels have struggled with the Moon’s abrasive surface materials and temperature extremes that can plummet to minus 173 degrees Celsius during lunar nights.

“The next era of lunar exploration demands a new kind of wheel – one that can sprint across razor-sharp regolith, shrug off extremely cold nights, and keep a rover rolling day after lunar day,” NASA stated in announcing the challenge.

The programme unfolds across three distinct phases. Phase 1, which opened on 28 August and runs until 4 November 2025, will reward the best conceptual designs and analyses. Phase 2, scheduled for January through April 2026, will fund prototype development. The final phase in May-June 2026 will test leading designs through live obstacle courses simulating lunar conditions.

For the concluding phase, NASA will deploy MicroChariot, a 45-kilogram test rover, to evaluate top-performing wheel designs at the Johnson Space Centre Rockyard facility in Houston, Texas. The testing ground will simulate the challenging lunar terrain that future missions must navigate.

The competition remains open to diverse participants, from university student teams and independent inventors to established aerospace companies, reflecting NASA’s broader strategy of engaging private sector innovation for space exploration technologies.

NASA mobility engineers will provide ongoing feedback throughout the competition phases, offering participants insights from the agency’s extensive experience in planetary rover operations, including successful missions to Mars.

The challenge comes as NASA intensifies preparations for the Artemis programme, which aims to establish a sustained human presence on the Moon and serve as a stepping stone for eventual Mars exploration missions.

Current lunar rover designs have faced limitations in speed, cargo capacity, and durability when operating across the Moon’s challenging surface conditions, creating demand for breakthrough mobility solutions that can support extended surface operations.

The competition timeline positions Phase 2 prototype funding to commence in January 2026, allowing successful Phase 1 participants several months to refine their concepts before advancing to hardware development.

VMI will display its automated Strainer Plate Cleaning Station, a significant innovation designed to address a longstanding challenge within the rubber manufacturing industry, at the upcoming Global Polymer Summit in Cleveland. This comes at a critical time of rapid economic expansion in the United States, largely fuelled by construction and industrial renewal, which is driving increased demand for high-quality, efficiently produced rubber components.

These components are essential across a vast spectrum of applications, from microscopic seals and industrial machinery to pipelines and specialised products for extreme environments. To keep pace, US manufacturers are actively seeking advanced equipment that combines superior quality, shorter lead times and robust stateside support. For over two decades, VMI has met these exact needs from its Ohio operations, offering German-engineered solutions supported by responsive local service.

The new Strainer Plate Cleaning Station exemplifies VMI's pioneering ‘Hands-off, Eyes-off’ automation philosophy, previously applied to its industry-standard tyre building machines. This system utilises advanced robotics to completely transform what has traditionally been one of the most labour-intensive, unpleasant and hazardous jobs in a rubber factory. The automated Strainer Plate Cleaning Station will be demonstrated in operation at VMI’s booth, number 1430, during the Global Polymer Summit from 8th to 11th September.

The benefits of this automation are substantial. Companies can reallocate skilled workers to more value-added production roles, thereby boosting overall productivity and driving down unit costs. This enhanced efficiency allows businesses to become more competitive and responsive to dynamic market demands. The system integrates seamlessly with VMI’s extrusion and gear pump systems, which are backed by proprietary management software that enables the flexible production of both standard and highly specialised components on a single platform.
