FAQ
Q Injection clamping force?
A
Projection area cm² × specific pressure (300-800 bar) = clamping force. Smartphone case 100-200 t; appliance housing 500-1500 t; auto bumper 2000-4000 t; battery box 5000-9000 t.
Q Extruder screw design?
A
L/D ratio: general 25-30; high mixing 30-36; very high 36-42 (twin screw). Compression ratio 3:1 for semi-crystalline (PE), 4:1 for amorphous (ABS, PC). Reifenhäuser and Coperion lead extruders.
Q Plastic recycling extrusion?
A
PCR and PIR recycling extrusion needs twin screw + vacuum devolatilization + multi-stage filtration. EREMA (AT) and Coperion lead recycling extrusion.
