Bladder Failure / Burst During Cycle

Curing

Visual Symptoms Rupture or splitting of the curing bladder resulting in steam leakage into the green tyre cavity.

Root Causes Excessive bladder cycles, incorrect bladder compound selection, or uneven mold closing pressure.

Corrective Actions Track bladder service life limits, inspect mold centering, and ensure proper lubrication application.

Root Causes Excessive bladder cycles, incorrect bladder compound selection, or uneven mold closing pressure.

Corrective Actions Track bladder service life limits, inspect mold centering, and ensure proper lubrication application.

Blistering / Interply Delamination

Curing

Visual Symptoms Swelling or pockets of air trapped between carcass plies or innerliner after vulcanization.

Root Causes Inadequate green tack, trapped air during building, or too rapid pressure release at press opening.

Corrective Actions Increase pre-cure vacuum extraction time, optimize stitcher pressure during tyre building, and slow down the initial depressurization phase.

Blisters / Air Pockets in Skim Coat

Calendering

Visual Symptoms Trapped air pockets or bubbles forming between the fabric cords and the rubber skim layer.

Root Causes Roll temperatures too high causing premature localized scorch, or trapped air during calendar nip pass.

Corrective Actions Optimize calendar roll temperature controllers and reduce roll speed to allow air escape before nip entry.
