ServicesOur Retreading Process
Initial Visual Inspection
Highly trained specialists perform a thorough visual inspection of the tyre casing before any other process steps are allowed to be made. The Boston retreading process requires a sound starting point, so this initial inspection already rejects casings which are damaged too badly. This is the first step in ensuring that a Boston is a Boston, anywhere and always.
Buffing
A buffing machine then removes excess remaining rubber from the casing and restores it to its ideal dimensions, preparing it to receive its new tread. Thanks to the Boston technology, the process and the accuracy, our specialists can make sure that individual casings will be turned into identical Boston retreads.
Skiving
During the skiving process, any superficial damages to the casing are carefully cleaned out. This is also the moment when the Boston operator can “save” your casing asset from the scrap pile. This process step serves a double purpose. It ensures that the casing is totally clean and ready to be retreaded, but it also guarantees that your retread will stay in good shape until the end of its new life… ready for possibly yet another retreading process!
Repairing
At the Repair station, section repairs are done to ensure any openings made by the Skiving operator are tightly sealed. Precured rubber is then fed from a hopper into the barrel of the extruder, where it is gradually melted by mechanical energy generated by a turning screw and by heaters arranged along the barrel. The softened rubber is then used to assume the shape of the repair opening.
Building
At this stage, the Boston pre-cured tread, with its purposely developed pattern and compound, is applied to the prepared casing. After careful measurement and tread-preparation, the building process finally transforms the previously worn out tyres into brand new Boston retreads. A layer of uncured rubber, which is applied between the casing and the new tread, will ensure a permanent bond between the two after the curing process. Here again, a specialized operator uses high-tech Boston equipment to ensure perfect uniformity and top quality finishing.
Curing
The curing – or “vulcanizing” – process permanently bonds the new Boston tread to the worn out casing. After the tyre is wrapped in an air-tight envelope, pressure and temperature are applied to transform the layer of uncured rubber into a final and irreversible elastic state. This ensures that the casing and tread will never separate again… until the next Boston retreading process, of course.
Final Inspection
After completion and final inspection, be it visual or machine inspection, the Boston operator grinds and paints the tyre and then approves the retreaded tyre for sale. He ensures that the final product meets the requirements to be a real Boston and that it looks like one!
