Retread Process
This is how we work
1. Get Specifications
Before any retreading is done we gather the required specifications i.e tyre size.
2. Plan
Due to our work load in our, planning is imperative for faster turn around time.
3. Work
Here we carry out the actual retreading process with quick turn around times.
Quality Policy
We are committed to consistently strive to improve in all our activities
-Continuous upgrading of technology and processes used in tyre retreading.
-Motivating and training the workforce.
-Continuous business growth by complete customer satisfaction
The retread Process Explained
Initial Inspection
At first we do visual and tactile examination of the casing. Thereafter we perfom a non-destructive shearography test or scan. This test is to detect separations in the carcass that are otherwise difficult to detect with the naked eye. If accepted, it will then go through the complete retread process.
Buffing
The buffing process removes the remaining tread and sidewall rubber to predetermined dimensions by using high speed revolving rasps and brushes. The machine used for this process is computer-controlled so that the exact and accurate dimensions are achieved. This ensures that the buffed casing is an exact fit for the matrix of mould for which it is destined. The granular residue and dust that is produced during this process is extracted by high powered fans and collected in large hoppers for recycling. Most of this material is processed into cushion backing used in the carpet industry.
Preparations
To locate any minute holes in the inner wall, the casing is subject to a penetration detection process whereby high voltage electricity is passed through the tyre while it is rotated. If a minute hole is located, an arc will be produced which stops the machine and identifies the location for a repair to be made. Larger holes in the casing are filled with compound and patched to rebuild the integral strength. Finally, the prepared casing is sprayed with a water-based adhesive, ready for the building process.
Warranty Policy
Retreaded tyres supplied by 3G Tyres carry a 3-month warranty against all defects in material and workmanship. The warranty does not cover consequential damages caused by service hazards, vehicle defects, pothole defects, etc.
The liability under this warranty is limited to make good the defects arising solely from the use of faulty material or workmanship on a pro-rata basis. Casing burst and/or air in casing is not covered under this warranty.
