The Inflatable Mandrels are shaped to the inside of the tire. They are light weight, easy to use and come with a 400 hour pro-rata warranty. VULCAN-VULCAP Inflatable Mandrels are available in a variety of sizes. VULCAN-VULCAP MANDREL ADAPTORS The VULCAN-VULCAP Mandrel Adaptors are designed to secure the Inflatable Mandrel in the mold cavity. Mandrel Adaptors are installed between Mandrel and Mold Cross Clamp. Mandrel Adaptors are available for various tire sizes. These are important for the protection of the Air Mandrels from damage. VULCAN-VULCAP INSIDE HEATPADS VULCAN-VULCAP Inside Heatpads are constructed of flexible heat resistant rubber designed to give "feather edge" flow over the patch and right up to the bead area. An internal thermostat control ensures even heat distribution of 290øF over the patch area throughout the cure cycle. The pad can be plugged into the mold control panel or a normal wall socket. It is available in 110V or 220V (2/4 amps). (Two voltages available.) AIR DIFFERENTIAL CONTROL is available as separate retrofit accessory or "built in" to new molds. The Air Differential Control automatically inflates inside mandrel and outside Airbags simultaneously maintaining differential of 12-15 lbs. higher pressure on the inside of the tire (pressure is typically 45 psi inside and 30 psi outside). VULCAN-VULCAP OUTSIDE HEATPADS VULCAN-VULCAP Heatpads conform to the profile of the tire. With thermostatic control technology it provides precise set point temperature throughout the Heatpad and ensures maximum adhesion for a dependable repair. All VULCAN-VULCAP Heatpads are built to  and  standards and certified to .   VULCAN-VULCAP OUTSIDE AIRBAGS VULCAN-VULCAP Outside Airbags are constructed of heat resistant rubber and outside high tensile heat resistant, pre-shrunk nylon covers. They provide pressure to the outside of the tire during the vulcanizing process. The Air Pressure Differential Control System regulates the pressure in the air bag relative to the Inflatable Mandrel.     VULCAN-VULCAP BEAD FILLER PADS The VULCAN-VULCAP Bead Filler Pads are used on top of the tire beads, between the Mandrel Adaptor and the Heatpad, to protect the Heatpad and Air Bag when repairing low profile tires.   VULCAN-VULCAP SIDE FILLER PADS The VULCAN-VULCAP Side Filler Pads are used with narrow tires. They fill the space between the Side Air Bag and the tire.                     VULCAN-VULCAP REPLACEMENT PARTS VULCAN-VULCAP Industries Inc. stocks a wide range of replacement parts for VULCAN, NATIONAL, Flexible Systems and Spotters (C-Clamps). We will supply parts for all VULCAN and NATIONAL Molds, no matter how old the model. See our cross reference list to get the part number for the Section Repair Mold model you have.

HEATPADS AND AIRBAGS FOR Vulcaflex® AND OTHER FLEXIBLE SYSTEMS

VULCAN-VULCAP now manufactures a full range of Thermocouple Heatpads and Airbags for all Strap, Flexible, OTR and Truck Tire Repair Systems.  Our Heatpads are fully compatible with MONARCH, NATIONAL or VULCAN systems.  They are equipped with the proper plugs for each system they are ordered for.  These pads generally are more rugged than pads manufactured by other companies and have a reputation for outlasting others.  


For certain applications, we do have L-shaped Heatpads that conform to the shoulder of the tire to be repaired.  These pads are better than thin, flat pads as they are already contoured for the shoulder of the tire.

L-SHAPED HEATPADS FOR Vulcaflex® AND OTHER FLEXIBLE SYSTEMS

Unique to the Vulcaflex®  trademark series of Heatpads which are also compatible with other flexible systems such as Monaflex and National, are our L-shaped Heatpads shown below.  These L-shaped Heatpads are molded to shape to conform better to the tire when performing shoulder repairs.  They have been developed by  VULCAN-VULCAP technicians based on over 60 years of experience in the design and building of tire repair equipment.

VULCAN–VULCAP TREAD LUG FILLER BAGS

 A new and easy Method to protect Heatpads when
curing Repairs in OTR Tires

The Problem

 
Taking the time to correctly fill in the voids of an OTR tire will extend the life of your Heatpad.

When the lug voids of the tread design are not filled in properly, the Heatpad is distorted when pushed into the voids by the pressure of the Airbag.  The Heating Element inside the Heatpad is then damaged and may cause the Heatpad to overheat.  This can result in a fire starting in the tire.

In the case of strap type curing systems, it can also damage the thermocouple sensor wires.



Solutions

There are a few different ways in which to fill in the tread voids:

(1)        Plaster of Paris - this is a good procedure to use but is very messy and time consuming.

(2)        Aluminum foil - this is easy to use but very often not enough tin foil is used.  The void looks like it has been filled but when air pressure is applied, the foil compresses into the tread void and the heatpad then becomes distorted.

(3)        Other types of fillers - these are always messy.

The Best Solution

VULCAN-VULCAP’s new Silica Sand filled Tread Lug Filler Bags are the best alternative to the above.

§         The Silica Sand is very fine and allows the sandbags to take the shape of the tread void.

§         The Tread Lug Filler Bags come in sets of 20 bags in various sizes.

§         We realize that this may not cover all the different size Lug Void Configurations, therefore additional bags can be made to customer specifications.

 
Please note:  Heatpads that fail because Tread Voids are not filled in properly are not covered under Warranty as the sharp Tread Edges destroy the Heating Elements!

Below are pictures of VULCAN-VULCAP Heatpads that were used and damaged beyond repair due to failure of using lug fillers.  This damages the Heatpads unnecessarily and is not covered under warranty.  It is very important to avoid this kind of costly mistake!

Another graphic example how a Heatpad was irreparably damaged and burnt out because the customer did not use lug fillers.  You will note how the lugs are imbedded in the Heatpad, destroying and thus shorting out the heating elements completely.
