CategoryClamping, Sheet Loading & Tool Setup
Clamp Pressure Imbalance
Diagnose unequal clamp force that causes sheet pull-in, edge tearing, air leakage, asymmetric draw, or inconsistent material distribution.
Thermoforming Wiki
Diagnose thermoforming defects by symptom, cause, process area, and material.
CategoryClamping, Sheet Loading & Tool Setup
Clamp Slip During Thermoforming
Stop sheet movement in the clamp frame by correcting grip, pressure, parallelism, edge temperature, contamination, sheet damage, and forming load.
CategoryClamping, Sheet Loading & Tool Setup
Clamp-Zone Tearing
Prevent tears at the clamped sheet edge by correcting temperature gradients, sharp grips, excessive force, damaged edges, pull-in, and poor frame alignment.
CategoryMaterials & Sheet Quality
Coextruded Tie-Layer Delamination
Diagnose interlayer separation caused by incompatible structures, weak tie layers, moisture, excessive strain, overheating, poor sheet manufacture, or trimming stress.
CategoryVacuum, Pressure & Pneumatics
Compressed Air Pressure Drop
Diagnose pressure forming and pre-stretch losses caused by undersized supply lines, shared demand, low receiver capacity, filters, valves, or leaks.
CategoryCooling, Shrinkage & Demolding
Condensation on Thermoforming Molds
Stop mold condensation that causes water spots, haze, poor texture transfer, contamination, corrosion, and unstable part release.
CategoryVacuum, Pressure & Pneumatics
Contaminated Compressed Air
Prevent oil, water, rust, and particulate contamination from marking sheet, blocking valves, damaging seals, or creating unstable pneumatic motion.
CategoryCooling, Shrinkage & Demolding
Cooling Fan Imbalance
Diagnose uneven external cooling caused by failed fans, blocked airflow, poor aiming, variable speed, drafts, or asymmetric part shielding.
CategoryCooling, Shrinkage & Demolding
Cooling Jig Marks and Distortion
Correct witness marks, locked dimensions, uneven shrinkage, and residual stress caused by poorly fitted thermoforming cooling jigs or nests.
CategoryCooling, Shrinkage & Demolding
Cooling Water Scale and Fouling
Prevent mineral scale, corrosion products, biological growth, and process residue from reducing heat transfer and blocking thermoforming mold circuits.
