Common Problems and Solutions in the heat Sealing process of canopy fabric

Welding Spark

Cause: Mold not level or high-frequency current setting too high.

Solution: Recalibrate mold level and adjust current to a reasonable range.

Weld Air Bubbles

Cause: Heat sealing temperature too high or membrane material damp.

Solution: Control temperature and ensure membrane material is dry.

Insufficient Weld Strength

Cause: Insufficient heat sealing pressure or time.

Solution: Increase pressure and extend heat sealing time.

Poor Sealing

Cause: Weld not fully fused or impurities present.

Solution: Clean membrane surface and ensure the heat-sealed area is flat.

Membrane Deformation

Cause: Uneven heat sealing temperature or insufficient cooling.

Solution: Heate evenly.
