Cold patching is a quick fix using adhesive strips, but it often fails under high heat or pressure. High-temperature vulcanization, on the other hand, chemically bonds the repair material to the tire through heat (around 180°C) and pressure, creating a permanent, heat-resistant, and tear-resistant seal — ideal for high-speed or heavy-load driving conditions.
I. Gunard tire repair machine requires no molds for easier and more efficient operation, specialized for heavily deformed damages on tire shoulders and sidewalls (the biggest advantage over ordinary flat vulcanizers)Ordinary flat vulcanizers only come with flat heating plates that cannot fit the cur
Many vehicle owners and auto repair shops have the same question: small nail holes can be fixed with cold patch repair, so why must high-temperature vulcanizers be used to repair damaged tire shoulders and sidewalls? Today, combining the special tire shoulder and sidewall vulcanizer from Gunard, we
Not all sidewall damage is beyond repair. Small cuts, punctures, or cracks (typically under 3cm) may be candidates for vulcanization repair. However, if the steel cord is exposed or the damage is larger than 3cm, replacement is recommended. Always consult a professional repair technician for an accu
Many drivers believe that any puncture on the tire shoulder or sidewall means an immediate replacement. In fact, with high-temperature vulcanization technology, these "difficult-to-repair" areas can be effectively fixed. The process uses heat and pressure to bond new rubber to the damaged
