Insufficient Infrared Welding Strength of PBT Products
Fenómeno do problema
After infrared welding of PBT products, the strength is insufficient and the weld line is fragile.
Análise das causas
The infrared welding parameters (heating time, pressure, weld depth) are improper; the welding surface is contaminated or oxidized.
Solução
Optimize the welding parameters; clean the welding surface before welding; use a suitable energy director structure.
Conclusão principal
PBT infrared welding requires optimized parameters.
