What are the most common extrusion blow molding defects?

Common defects include excessive flash, weak or cut pinch-off, uneven wall thickness, thin corners, parison sag or curl, melt fracture, bubbles, black specks, die lines, incomplete blowing, blow-outs, warpage and leaks.

What causes uneven wall thickness in blow molding?

Possible causes include profile position, die centering, parison sag, unstable extrusion or shot size, mold alignment, unequal cooling and the amount of stretch required by the part geometry.

How do you reduce flash in extrusion blow molding?

First check where the flash occurs, part weight, parison placement, mold-close completion, clamp behavior, alignment and pinch-off condition. Correct a closure or tooling fault before changing global part weight.

Why are there bubbles in a blow molded part?

Possible causes include condensation or moisture, trapped gas, insufficient melt uniformity, material leakage, degraded material and contamination. Check the resin requirement and material path before changing the process.

Can parison programming fix every thin-wall defect?

No. Parison programming cannot reliably correct die misalignment, unstable extrusion, damaged tooling, poor cooling, incorrect mold position or a malfunctioning actuator.

What should be changed first during blow molding troubleshooting?

First restore and verify the approved material, recipe, utility and machine-condition baseline. After identifying the most likely layer, change one controlled variable and repeat the same part measurements.

Why does the same defect return on another shift?

Recurring defects often return when recipe revisions, material changes, utility readings, alarms and corrective actions are not recorded consistently. A shared defect log and protected baseline make the process repeatable.
