Unstable Dimensions in CMC Extrusion
Sorun Belirtisi
Cross-sectional dimension of CMC extruded products fluctuates ±10%, and there are also periodic changes in the length direction
Neden Analizi
Feeding amount is unstable and feed screw speed fluctuates; extrusion temperature fluctuates periodically ±5°C; haul-off speed does not match extrusion speed
Çözüm
1)Use loss-in-weight feeder to ensure stable feeding; 2)PID control accuracy ±1°C for each extruder zone temperature; 3)Closed-loop control of haul-off speed linked with extrusion speed; 4)Processing temperature controlled at 20-25±5°C
Temel Çıkarım
Extrusion dimensional stability depends on feeding accuracy, temperature control and haul-off synchronization
