PARA Clamping Force Configuration
Problem Phenomenon
Flash and mold expansion in PARA production; clamping force estimated at 1T/cm² is insufficient, and equipment configuration is improper.
Cause Analysis
PARA injection requires a clamping tonnage of 1T/cm² (4T/in²) of projected area; high-pressure injection processes have high clamping requirements; insufficient equipment capacity; mold strength matching.
Solution
①Calculate clamping force at 1T/cm² of projected area; ②Check equipment capacity; ③Recheck clamping margin for high-pressure processes; ④Mold strength verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PARA's 1T/cm² clamping standard is the basis for equipment selection; the safety margin of high-pressure processes must be rechecked; mold strength is verified in parallel.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
