Unstable Weight of CMC Injection Molded Products
Problem Phenomenon
Weight of CMC injection molded products fluctuates ±3%, exceeding the ±1% accuracy requirement
Cause Analysis
Injection amount is unstable and screw back position is inconsistent; holding time fluctuates; feeding amount is unstable; CMC density varies ±2%
Solution
1)Displacement sensor to precisely control screw back position; 2)Stabilize holding time and pressure; 3)Precisely set V/P switchover point; 4)Inspect density differences between batches
Key Takeaway
Product weight stability depends on injection amount accuracy and holding consistency
