The revolutionary Direct-Foam-in-Tire technology with subsequent laser activation eliminates cost and many challenges related to bonding of preformed foam patches into tires (Foam-in-Tire bonding).
Traditional foam-in-tire bonding for silent tires comes with complexity cost related to many different preformed patch sizes, logistical challenges related to bulky foam patches of different sizes and limited real estate at the manufacturing line, raw material waste from cutting, automation constraints, and challenging quality control of the actual adhesive bond to the foam.
Henkel’s patented LOCTITE LASER-FIT™ Process transforms this workflow with a three-step innovation: Tire Cleaning → Foam Application → Laser Activation. By directly applying the liquid reactive foam formulation into the tire, where it immediately expands and cures at ambient temperature to form an acoustic foam, this solution eliminates preformed foam patches, manual handling, and the entire adhesive bonding process. In order to optimize the acoustic damping performance and to avoid excessive thermal insulation, the foam’s skin can be removed by a fully integrated laser process with a 4JET Laser System.
