Time, Temperature and Pressure – The Keys to Proper and Lasting Tire Repairs

Vulcan-Vulcap Industries Inc. – The World Leader in Section Repair Equipment supplies these important elements with their Section Repair Molds, MV Series, Vulcaflex® and VRC OTR and VTRC Truck, Tractor and Grader Tire Repair Clamps.

To successfully vulcanize a repaired injury in a tire, three things are needed: Time, Temperature and Pressure

Vulcan-Vulcap Industries supplies all three with our unique Section Repair Mold Systems. Molds are compact, rugged and light-weight. The unique Airbag System provides even pressure. The thermostatically controlled heating pads supply the correct curing temperatures. The experienced operator then must ensure proper curing times.

From the smallest passenger tire through to the largest OTR (earthmover) tire, we have a proven system for your tire repair operation.

We repair today’s radial tires distortion free by using our Vulcan-Vulcap Inflatable Mandrel System. A shaped air mandrel is utilized that grows to fit the tire you are repairing, using an air differential control panel, supplying the correct pressure both inside and outside of the tire, providing even pressure over the injured area.

Heating units for both inside and outside are provided with molded Heatpads, which are controlled at curing temperature for a good, solid cure. Time is very critical, as rubber cures at different rates. Follow carefully the instructions of the rubber manufacturer.

As all Vulcan-Vulcap Section Molds cure from both inside and outside generally, a curing cycle of approx. 4 minutes per 1/32″ of rubber thickness (depending on type of rubber) can be cured, temperature being held at approx. 280-300°F automatically. Please determine exact curing times for the rubber you are using from the manufacturer!
