Highly qualified operators, using sophisticated equipment especially developed for this use, determine the characteristics of the casings and select the best ones.
In order to ensure the contour of the tire is at the correct radius, the casing is inflated to the proper pressure. This process removes the worn tread surface leaving a surface on the casing that provides the best possible adhesion value for the new treads application.
The removal of all injuries identified during the inspection process and replaces the damaged material with structurally sound materials that returns the casing to a useful life and allows the tires to run their full life cycle.
Skiving involves smoothing the rubber to further refine any imperfect areas. Those imperfect rubber and broken wire areas are smoothed in a belt package to prepare it for the rubber extrusion application. Those areas are left with a beautiful clean surface.
Precision Cushion Rubber Application uses a state-of-the-art computer controlled extruder that applies in a continuous splice-free strip. Matched tire diameters give you the benefit of even loading, smooth ride, even wear, lower cost per mile and improved fuel efficiency.
Precision Rubber Appplication
AcuTread® Precision Rubber Application uses a state-of-the-art computer controlled pin barrel extruder that applies a continuous splice-free strip. The benefit of this process is matching tire diameters that offers a smooth, even ride and wear, lower cost per mile and improved fuel efficiency.
Tread Molding and Curing
AcuTread® Tread Molding and Curing Technology uses segmented curing presses with three heat zones to ensure minimal heat exposure to the casings while in the presses. AcuTread® Molding uses high internal air pressure which results in superior adhesion values.
A thorough inspection of the retread follows the molding and curing process. This ensures the quality of the final product is at an unrivaled level. Each new tire is run one final time over the NDT, then the final visual inspection. Done.
