Mold Bridging in Thermoforming
Correct sheet bridging across recesses or between features by changing heat, pre-stretch, venting, cavity spacing, downholders, and contact sequence.
Thermoforming Wiki
Diagnose thermoforming defects by symptom, cause, process area, and material.
CategoryCooling, Shrinkage & Demolding
Mold Scuffing During Part Release
Eliminate drag and scuff marks caused by low draft, rough tool surfaces, contamination, shrinkage, misalignment, or premature release.
CategorySurface Quality & Contamination
Mold Surface Blemishes
Eliminate recurring spots, pits, scratches, and pickup marks transferred from damaged, dirty, corroded, or poorly repaired thermoforming tools.
CategoryCooling, Shrinkage & Demolding
Mold Temperature Drift
Diagnose gradual mold temperature change that alters cooling time, shrinkage, release, detail, gloss, and dimensional stability during a production run.
CategoryMold Design & Material Distribution
Mold Thermal Expansion Distortion
Control dimensional drift caused by nonuniform mold temperature, thermal expansion, cooling-circuit imbalance, weak support, or unstable startup conditions.
CategoryClamping, Sheet Loading & Tool Setup
Mold-to-Baseboard Seal Failure
Find leakage between the mold, baseboard, vacuum box, inserts, and mounting hardware that weakens local or overall thermoforming vacuum.
CategoryCooling, Shrinkage & Demolding
Multi-Cavity Cooling Imbalance
Correct cavity-to-cavity temperature differences that produce unequal shrinkage, release timing, dimensions, gloss, and cycle stability.
CategoryMold Design & Material Distribution
Multi-Cavity Material Distribution
Correct cavity-to-cavity thickness variation caused by thermal gradients, unequal draw demand, plug differences, sheet tension, and array layout.
CategoryVacuum, Pressure & Pneumatics
Multi-Cavity Vacuum Imbalance
Correct cavities that form at different rates because of unequal venting, manifold resistance, local leaks, thermal gradients, or cavity position.
CategoryTrimming & Secondary Operations
Multilayer Sheet Delamination During Trimming
Prevent layer separation at trimmed edges by checking tie-layer strength, moisture, forming strain, cutter condition, support, impact, and cut direction.
