TPE Product Demolding Draft Angle
Fenómeno del problema
Demolding drag marks.
Análisis de la causa
Insufficient draft angle; soft materials are more sensitive.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry information and should be confirmed first during troubleshooting
Solución
①Increase the draft angle; ②Polish the cavity; ③Balance the ejection; ④Evaluate the surface texture.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusión clave
Take the upper limit of the draft angle for soft materials.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
