Domanda: domanda

• Simultaneously meets compression and 5°C low-temperature bend requirements
• High capacity, fast production speed
• Cost-competitive formulation

Problem:

• Compression, hand-bend, and low- temperature performance cannot be satisfied simultaneously
• Production speed limited to only 10-12 m/min
• Non-continuous stable production,narrow processing range
• High material costs

Root Cause Analysis:

• Formulation trade-off conflict: Tuned stiff for compression, but needs toughness for hand- bend and low- temperature bending. The balance is off, so all three can’t be met at once.
• Narrow processing window: Thermal stability and fusion control are weak; once speed increases, the process becomes unstable, capping the line at 10-12 m/min.
• High cost: Expensive package plus slow runs and more scrap drive up cost per meter.
