Improper LCP Mold Temperature Setting Affects Performance
Problem Phenomenon
【Problem Phenomenon】When the mold temperature is too low, the product surface is rough and weld lines are weaker; when too high, demolding deformation occurs and the cycle lengthens
Cause Analysis
Mold temperature affects LCP crystallization rate and surface layer orientation: low mold temperature makes the skin freeze quickly with strong orientation and weak weld lines; high mold temperature improves surface and welding but extends cooling; the MEMS textbook recommends a mold temperature of 70-130℃
Solution
Set the mold temperature in the 70-130℃ range, taking the upper or lower limit according to appearance and strength requirements; control the mold temperature difference across cavity points within 5℃; extend cooling at high mold temperature to prevent deformation
Key Takeaway
Mold temperature 70-130℃ is the performance adjustment knob of LCP; take the value by weighing appearance against strength; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
