CategoryMold Design & Material Distribution
Oil Canning in Thermoformed Panels
Diagnose unstable flat panels that pop or rock after forming and correct geometry, thickness, cooling, residual stress, support, and trim conditions.
Thermoforming Wiki
Diagnose thermoforming defects by symptom, cause, process area, and material.
CategorySurface Quality & Contamination
Oil Contamination in Thermoforming
Identify oil and lubricant contamination that causes stains, adhesion loss, surface defects, smoke, or bonding failure and remove its source safely.
CategoryHeating & Sheet Temperature
Orange Peel Texture in Thermoforming
Diagnose orange peel texture on thermoformed parts and correct excessive heat soak, unstable sheet surfaces, uneven heating, or incoming-sheet defects.
CategoryMaterials & Sheet Quality
PET Crystallization Haze
Understand whitening and haze from PET crystallization and control resin history, sheet heating, dwell, forming speed, mold temperature, and cooling.
CategoryMaterials & Sheet Quality
PETG Overheating Haze
Prevent haze, bubbles, orange peel, and surface distortion in PETG by controlling heat exposure, sheet condition, temperature uniformity, and cooling.
CategoryMaterials & Sheet Quality
PETG Stringing During Trimming
Stop PETG trim strings, melted edges, burrs, and reattachment by correcting cutter sharpness, speed, feed, chip removal, support, and sheet temperature.
CategoryProcess Control & Machine Diagnostics
PID Temperature Overshoot
Correct heater and mold temperature overshoot caused by aggressive tuning, sensor lag, output limits, startup conditions, or changing thermal load.
CategoryMaterials & Sheet Quality
PVC Thermal Degradation in Thermoforming
Recognize PVC discoloration, odor, surface damage, and gas release caused by excessive heat, long dwell, poor ventilation, contamination, or unstable control.
CategoryCooling, Shrinkage & Demolding
Part Sticking in a Thermoforming Mold
Diagnose parts that stick because of insufficient draft, shrinkage, hot release, roughness, contamination, vacuum lock, or a true undercut.
CategoryPre-Stretch & Plug Assist
Plug Assist Misalignment
Identify off-center or tilted plug motion that causes one-sided thinning, contact marks, tearing, cavity variation, and uneven wall distribution.
