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.”

Wallace Instruments, a globally recognised leader in rubber testing equipment, has expanded its United Kingdom-manufactured specimen preparation lineup with the launch of the WAS3 Pneumatic Cutting Press. The new device joins the company’s range of rubber testing equipment.

Unlike manual cutting methods, pneumatic systems apply consistent force on every cycle, eliminating operator fatigue and variability. Poorly prepared specimens with uneven edges or internal stress can compromise test accuracy, while the pneumatic approach also reduces repetitive physical strain, supporting technician wellbeing during long production runs.

The WAS3 prioritises safe single-operator use through a two-button activation system requiring both buttons to be pressed within half a second, preventing any hand contact with the cutting area. Additional three-sided protective guards further enhance operational safety.

Delivering 15 kN of cutting force, the press easily cuts through 10-mm thick, 95 Shore A rubber sheet using five bar of filtered air pressure. It works with existing Wallace cutting dies, so laboratories can integrate the unit without replacing current tooling, and its compact footprint suits both lab and production environments.

Chris Norval, Managing Director, Wallace Instruments, said, "Specimen preparation is the foundation of accurate rubber testing. With the WAS3, we focused on practical safety, dependable cutting performance and drop-in compatibility. Labs get a compact pneumatic press that fits the air lines already in place, uses their current Wallace dies and delivers consistent results for every operator – because when specimen quality is controlled, you can have confidence in the results that follow."

DUNLOP (company name: Sumitomo Rubber Industries, Ltd.) has teamed up with Fujitsu Limited to create an artificial intelligence (AI) surrogate model that predicts tyre performance rapidly and with high precision. The breakthrough was validated in a proof of concept tied to DUNLOP’s digital transformation strategy. When applied to tyre deformation upon road contact, the technology slashed analysis time by 90 percent, from 45 minutes to just 5 minutes while processing nearly 600,000 mesh elements.

Based on these results, both firms will build a design support tool, aiming for deployment at DUNLOP by April 2027. The system runs on FUJITSU MONAKA, a next-generation energy efficient Arm-based CPU.

Tyre design typically relies on finite element method (FEM) analysis, where finer mesh grids boost accuracy but increase calculation time and costs. To tackle this, the partners developed an AI surrogate model that solves FEM equations using past data. The model, based on the Graph Neural Network algorithm, predicted contact shape with 87.7 percent accuracy, enabling faster decisions and lower costs.

Select findings will be shared at the 31st Computational Engineering Conference starting 3 June 2026. By December 2026, both companies will test the model on a FUJITSU MONAKA prototype to refine speed and power use.

Under its long-term strategy R.I.S.E. 2035, DUNLOP seeks to provide new experiential value from rubber. Through this co creation, the tyre maker will enhance its analytical technologies and strengthen innovation. Fujitsu will promote this approach across large scale FEM analysis in automotive and other manufacturing sectors, contributing to carbon neutrality via an AI platform combining FUJITSU MONAKA and GNN.
