Insufficient Infrared Welding Strength of PBT Products
Fenómeno del problema
After infrared welding of PBT products, the strength is insufficient and the weld line is fragile.
Análisis de la causa
The infrared welding parameters (heating time, pressure, weld depth) are improper; the welding surface is contaminated or oxidized.
Solución
Optimize the welding parameters; clean the welding surface before welding; use a suitable energy director structure.
Conclusión clave
PBT infrared welding requires optimized parameters.
