Retread EquipmentVULCAN-VULCAP Retread Equipment VULCAN-VULCAP MV-50 SECTION REPAIR MOLD

Features and benefits

Designed for O.T.R. Equipment Tire Repair.
Handles tire sizes from 36.00 x 51 through 45/65/45 and new generation giant sizes 50/80/57, 54, 5/80/57 & 53, 5/85/55.
Handles up to 36" x 36" (91cm x 91cm) patch.
The Vulcanizer repair process allows the rubber to flow during curing in both the plug area and between the patch and inner lining of the casing to form a dense, sealed repair that will not leak or fail.
50" (127 cm.) Expandable Steel Cavity simplifies loading and unloading tire.
Built-in Automatic Air Differential Control cures plug and patch simultaneously.
Zero distortion on radial and bias ply tires.
Rugged low profile, self standing design.
Expandable High Tensile Steel Shell Cavity simplifies tire loading and unloading, and maximizes stability.
Outside Heatpad conforms to our tire profile.
No time consuming, tedious straps required to secure the curing process.
Available in Electric or Steam configuration and requires only 45 psi curing pressure.
Pressure and heat for maximum adhesion of patch to casing.
Energy and cost efficient for uniform, quality cures and lower operating costs.
400 cure hour or 6 month warranty on parts and Heatpads.
Total pressure at 58,320 lbs is applied on maximum patch size to produce a dense, long lasting compression cure that will outlast any open steam cure.

New Features

This latest model of our OTR Section Mold family allows the operator to quickly set up for 3 basic widths in order to easily accommodate various tire sizes.  This eliminates the use of bulky filler pads.  It also saves time and considerably shortens set-up.

 

Handles tire sizes from 36.00 x 51 up to 53.5/85/57 or Tire Cross Section of minimum 36" to maximum 59".


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!
