Uneven wall thickness of PET thermoformed products
Fenómeno del problema
After '2079851475616104458 of PET sheet, product wall thickness is severely uneven, with corners too thin or even ruptured.
Análisis de la causa
Uneven sheet heating causes local temperature differences; forming mold temperature distribution is uneven; forming speed is too fast without full stretching.
Solución
Optimize zone control of the heating oven to make sheet temperature uniform (100-120°C); adjust mold temperature distribution; use plug-assist forming.
Conclusión clave
PET '2079851475616104458 wall thickness control depends on sheet heating uniformity and the forming process.
