1.Material Issues: High recyclate content, moisture, or poor flowability cause unstable feeding and plastication.
2.Suboptimal Extruder/Die: Screw design (compression ratio, mixing) mismatched with material, or poor die design, limits efficiency.
3.Downstream Limitations: Inefficient sizing/cooling (low vacuum, poor water flow) or haul-off slippage cap maximum speed.
4.Unoptimized Process: Parameters (temperature, speeds, draw ratio) not fine-tuned to the optimal window.
5.Poor Line Synchronization (Core Issue): “Mixed-fleet” equipment from different brands lacks control compatibility, preventing stable high-speed operation.
The Midtech Solution: Opt for Suzhou Midtech Machinery’s turnkey line. We ensure seamless synergy—from material handling and custom screw/die design to integrated downstream and unified controls—guaranteeing maximum output through expert commissioning.
