Bandag Process


Receiving

This is the point where all casings are dropped off and taken in for the retreading process.


Receiving
Initial Inspection NDT IIB
An electronic inspection designed to find all “through-the-tire” penetrations in the crown and sidewall areas.


Initial Inspection NDT IIB
Shearography

An inspection to determine the conditions within the casing. The casing is subjected to a vacuum while lasers measure surface anomalies (ie: expanding pockets of air). An animated visual of the anomalies aids in determining the casing's condition. At the end of the initial inspection, information like casing condition, casing age and fleet specifications are considered to determine if the tire can be retreaded.


Shearography
Buffer

The casing is inflated to operational pressure. The process removes the worn tread surface, trues up the roundness and prepares the surface for a new tread.


Buffer
Skive Station

The point where all penetrations found in the crown are cleaned out and prepared for proper repair.


Skive Station
Nail Hole Repair Station

Removing all injuries identified during Initial Inspection and replacing the material with structurally sound materials that will return the casing to a useful life.


Nail Hole Repair Station
Extruder (Applying Cushion)

In a one step process, an uncured bonding layer is extruded onto the prepared casing surface, all skives are filled, and the shoulders are stripped. The casing is now ready for its new tread.


Extruder (Applying Cushion)
Builder

Automatically applies a new tread so it is straight, centered on the casing, and the end splices match.


Builder
Envelope Spreader

Encases the uncured, built tire in an elastic envelope in preparation for curing.


Envelope Spreader
Arc Stand

Helps support the casing while an air tight lock ring is placed to help seal the envelope for the curing process.


Arc Stand
Air Evacuation

Vacuums all air out of the envelope for curing.


Air Evacuation
Curing Chamber

An autoclave-type device that applies heat and pressure, and over time, causes the bonding layer in the built tire to cure; permanently adhering the new tread to the prepared casing.


Curing Chamber
Painter

Paints the sidewalls on the finished tire.


Painter
Shipping

Area where finished tires are stored waiting to be shipped.
