PCABS mold temperature
Problem Phenomenon
PC/ABS mold temperature differences between 60-80℃ and 70-100℃, balance between surface and weld line.
Cause Analysis
PC/ABS mold temperature 60-80℃ (Sales Plastics) or 70-100℃ (Textileus); high mold temperature improves weld line strength and surface gloss; low mold temperature shortens the cycle; internal stress management.
Solution
①Mold temperature 60-100℃ according to grade; ②high mold temperature for surface and weld line; ③low mold temperature for cycle; ④stress evaluation; ⑤uniformity management.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Grade differences in PCABS mold temperature must be confirmed; high mold temperature is the quality choice; balance and optimize the cycle.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
