Slow extrusion speed of ETFE insulated wire
Problem Phenomenon
Low production efficiency of ETFE wire coating
Cause Analysis
ETFE melt produces melt fracture at excessively high speed, limiting line speed
Solution
Optimize die design to reduce melt fracture tendency; precisely control temperature
Key Takeaway
In ETFE cable extrusion, a balance must be struck between high speed and surface quality
