Tyre retreading tqm

  1. 1. TQM Of Tyre retreading co. Shrund Kalse
  2. 2. Mathematics and software: The mathematical support concerns the development of a statistical model that will determine the performance of a retreaded tyre based on characteristics of the tyre and the retreading process. The statistical model has been defined and properly validated
  3. 3. Retread Initial Inspection • Grazing Light Inspection: The first step is to verify the condition of the incoming casing. • Grazing light technique for inspecting sidewalls from shoulder to bead. This helps technicians detect subtle irregularities, which may indicate potential problem areas. • Retreading Plant have specific and measured lighting standards for inspection and trained technicians to accurately access each casing.
  4. 4. • Electronic Liner Inspection: Inner liner penetrations too small to spot visually can cause big problems. • Advanced X-Ray System: Suspected steel damage, identified during Grazing Light Inspection, is examined by X-Ray. • Buffing: uses an automated computer-controlled radial buffing system guided by a casing specification database & continuous undertread measurement to ensure optimal undertread depth.
  5. 5. Retread Process • Repairs: The proper preparation of the repair area and correct placement of the repair unit. All tools are inspected and replaced as needed. • Pre-Mold: using a computer-controlled Tread Builder to ensure the correct positioning of the new tread- reduces tread-building variables with the tread automatically cut to the correct length to optimize compression of the tread at the joint.
  6. 6. • Custom Mold: Cushion Extrusion and Tread Building: uses computer precision to control the extrusion of a single slab of tread rubber. This extrusion, which is similar to new tire construction, is strictly controlled for width and thickness for a proper fit of the casing and tread in the mold. • Final Inspection: The crown, sidewalls, beads, and interior are examined by a skilled technician to ensure new retread. CIA and x-ray are available to verify repairs and audit the final retread.
