What machine is used to repair sidewall cracks? What are the advantages of professional tire repair

Many car owners and auto repair professionals are aware that the most vulnerable parts of a tire are not the tread, but the sidewall and shoulder. In daily driving, crushing the road, high-speed gravel impact, low-speed scratching, and long-term heavy load bumps can all cause small cracks, scratches, cracking, delamination and air leakage on the tire sidewall. Compared to simple nail hole damage on the tire surface, sidewall cracks belong to structural damage of the tire, which cannot be repaired by ordinary tire repair methods. Forced repair will only bury safety hazards such as tire blowouts, leaks, and bulges. Many stores have encountered sidewall cracking problems and can only advise car owners to replace the tires directly, which not only increases the cost of car use for car owners, but also causes stores to miss out on a large number of profit opportunities.

In response to the industry challenge of repairing sidewall cracks, our Gunard tire repair machine has launched this safe, compliant, and long-lasting repair equipment, the high-temperature vulcanization repair machine (specifically designed for sidewall and shoulder vulcanization), which is also the core standard equipment for professional tire hard injury repair stores. Different from the traditional physical bonding repair mode of cold patching, rubber strips, and ordinary mushroom nails, the high-temperature vulcanization repair machine replicates the tire's original production process. Through an intelligent operation mode of precise temperature control, constant temperature pressure, and timed vulcanization, the specialized raw rubber material undergoes cross-linking chemical reactions with the rubber molecules in the damaged parts of the tire sidewall, achieving deep molecular fusion. After repair, the damaged parts are seamlessly integrated with the original tire body, completely solving the problems of repeated air leakage, cracking, and delamination of the sidewall cracks.

The core reason why ordinary tire repair equipment on the market cannot repair sidewall cracks is the limitation of the repair principle. Cold subsidy patches rely solely on physical bonding with adhesive, and the sidewall is the area with the largest bending and stretching deformation of the tire. During vehicle operation, the sidewall continues to stretch and bend, and adhesive patches are prone to detachment and delamination; Rubber strips are temporary emergency seals that cannot repair structural damage to the tire sidewall. They can also widen the damaged area, allowing rainwater and water vapor to seep into the interior of the tire body through the cracks, corroding the internal steel cord and accelerating tire scrapping. Conventional mushroom nails are only suitable for vertical nail holes on the tire surface and cannot fit the curved surface of the tire sidewall. After repair, they are subjected to uneven stress and are prone to further damage.

The Gunard high-temperature sidewall vulcanization repair machine has been specially optimized for sidewall repair, without the need for molds or precise temperature control systems, and can be adapted to cars SUV、 Small cracks, shallow cracks, scratches, minor delamination and other damages on the sidewall of various vehicle models such as light-duty trucks and explosion-proof tires. The equipment can accurately regulate the vulcanization temperature of 140-185 ℃, with constant pressure support and intelligent timing throughout the process, eliminating the drawbacks of old-fashioned fire repair temperature control, tire body damage, and rubber over sulfurization and brittleness. Novices can also standardize their operations.

From the perspective of repair effect, the sidewall cracks repaired by high-temperature vulcanization have flexibility, tensile strength, and airtightness that are close to the original tire standards. They are resistant to high temperatures, bending, and heavy loads, and can run on highways and long distances normally, completely eliminating the trouble of repeated repairs. For auto repair shops, equipped with this Gunnar tire repair equipment, they can undertake sidewall hard injury repair services that other shops cannot handle, significantly increasing the unit price and core competitiveness, and getting rid of the problem of low price and fast repair.

It should be noted that this tire repair equipment is only suitable for repairing superficial cracks, minor damages, and other repairable injuries on the tire sidewall. If the tire sidewall curtain line breaks extensively, the crack is too long, or there is severe bulging and deformation, it is considered irreversible serious injury. To ensure driving safety, it is not recommended to repair it and the car tire needs to be replaced directly.
