PCABS Mold Deposit
Fenómeno do problema
[Problem Phenomenon] PC/ABS long-term production causes mold surface deposit and venting blockage
Análise das causas
Flame retardants and additives precipitate and deposit; more obvious in flame-retardant grades; high mold temperature accelerates migration; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
Regularly clean mold venting; analyze deposits and adjust the formula; shorten the cleaning cycle for flame-retardant materials; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusão principal
PC/ABS mold deposits are cleaned regularly, more frequently for flame-retardant materials; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
