VULCAN-VULCAP V37.5 Section Repair Molds previously were supplied with a Mechanical Air and Time Control System and with Heatpads controlled by internal built-in Thermostats.

Due to the future unavailability of internally built in Thermostats, we will rebuilt any older models of VULCAN-VULCAP Section Repair Molds and convert them to Thermocouple controlled Heatpads.  These Section Repair Molds can now be retrofitted with Thermocouple Heatpads which are externally controlled by a state-of-the-art Control System as described below:

    Ability to add tire number, tire size and customer name to data logging screen, thus providing repair history for each tire.
    All stored data can easily be downloaded via memory stick into an Excel Spreadsheet to a PC for further analysis and record keeping. 
  (Click here for Template of Excel Spreadsheet to download Repair Data to a PC from Memory Stick!)  
    Remote access capabilities.  VULCAN-VULCAP Technicians can remotely connect to your system via internet should you encounter 
operational questions.
    System measurements and indicators can easily be switched from English to Metric, touching appropriate button.

This new generation of VULCAN-VULCAP Section Repair Molds are light-weight and cost-effective.  If proper procedures are followed, repaired injuries can be guaranteed for the life of the tire.  The repair is a true vulcanizing repair, where the rubber flows during curing both in the plug area and between the patch and inner casing liner.  This is not the case with chemical pre-cured patch repairs.  All VULCAN-VULCAP models of Section Repair Molds are patented and are the result of over 50 years of successful research and development for the independent tire repair and tire retread industry.

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!
