The VULCAN-VULCAP Section Repair Molds are light-weight and cost-effective.  If proper repair procedures are followed, repaired injuries can be guaranteed for the life of the tire.  The repair is a true vulcanising 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.

 

COVERED UNDER U.S. PATENT.

 

All VULCAN-VULCAP Heatpads are built to  and  standards 
and certified to .

VULCAN-VULCAP MV Series Section Repair Molds with Thermocouple Heatpads 

 

VULCAN-VULCAP MV Series 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 have to convert to Thermcouple controlled Heatpads.  The MV Series Section Repair Molds will now be supplied with Thermocouple Heatpads which are externally controlled by a state-of-the-art Control System as described below:

 

Vulcatouch®  OTR Control System for  VULCAN-VULCAP  MV Series 
Section Repair Molds 

VULCAN-VULCAP Industries Inc. is now offering our time proven and reliable MV Series Section Repair Molds with the latest development in control technology for the curing of repairs on OTR tires.  This is a PLC based Control System with many advanced safety features and data logging capabilities.  Reliable PLCs have long been utilized in automobile engines, robots and production machinery.  Now VULCAN-VULCAP has developed an easy to use control system using a reliable PLC.  This technology with a full colour touch screen, thus the name Vulcatouch®, is custom programmed to perform and monitor your OTR repair vulcanizing cycle.

Features of the
Vulcatouch® OTR Control System:

   

Easy to operate 8” full colour touch screen as operator interface.  Can also simultaneously be remotely displayed on PC via Ethernet.
    Curing temperature, pressure and curing time settings are done with a touch of a finger tip.
    Ability to attach 2 additional auxiliary thermocouples for extra monitoring of temperatures during the curing of the repair.
    Digital temperature controls and display of Inside and Outside Heatpads plus amperage indicators.
    Automatic control of Inside/Outside Airbag pressure.
    Audio Alarm – Continuous beep to indicate overheating.  Machine will shut off power to Headpads. 
    Audio Alarm – Continuous beep to indicate excessive air pressure in Airbags.  Machine will exhaust air until set air pressure is reached.
    Audio Alarm if one or both Heatpads malfunction at beginning or during cycle.
    Audio signal - Intermittent beeps to indicate end of curing cycle.
    Automatic storage of alarm history.
    Main control screen indicates curing time remaining.
    Data logging screen and data storage.  System will store automatically each curing cycle date, time, temperature and pressure.
    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.

New Thermocouple Headpads for VULCAN-VULCAP OTR Section Repair Molds 

Up to now the Heatpads in VULCAN-VULCAP Section Repair Molds were controlled by internal built-in Thermostats.  However due to the future unavailability of built-in Thermostats and in response to the latest market demands VULCAN-VULCAP will start supplying Thermocouple Heatpads controlled by an external Thermostat Control System.  We will continue to supply Heatpads with internal built-in Thermostats for a limited time only.  After this, Thermocouple controlled Heatpads only will be supplied.

How to convert a VULCAN-VULCAP Section Repair Mold 
to Thermocouple Heatpads?


A. The Air System will remain the same.
B. A VULCAN-VULCAP Basic Digital Thermocouple Heatpad Control Panel as described below will be required:

Overall view of Heatpad Control System

The VULCAN-VULCAP Vulcaflex® Basic Digital Thermocouple Heatpad Control Panel is an economical and practical  Heatpad Control Unit for all VULCAN-VULCAP OTR Section Repair Molds to control Thermocouple Heatpads.    This handy little, portable Control Panel is an excellent solution for repair shops who want a safe and reliable system to control Thermocouple Heatpads for Truck, Tractor and OTR Tire repairs.  These users are either controlling their Airbags manually or are using a VULCAN-VULCAP Section Repair Mold with existing Air Control Panel for Airbags.  The digital instrumentation is clear and easily readable.  The maximum Heating Temperature and Curing Time can be set quickly and easily.  (Maximum Curing Temperature is programmed to 300°F/140°C.)  The Audio Alarm will sound when Heatpads overheat

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!
