DEMAND:

• Target output 230-250 kg/h
• Physical properties meeting current standards

Problem:

• Production output maximum ~200 kg/h. can not be higher
• Rough inner/outer walls, flow lines, and easily be degraded at high-speed extrusion
• Insufficient toughness and narrowed processing window
• Vicat softening temperature was below 110 degrees

Root Cause Analysis

• Original lubrication system:optimized for low-medium speed only,high-speed suitability is limited.
• MBS toughener:causing rapid internal temperature rise, increasing production complexity and difficulty.
• Original formula limitations: Not suitable for high-speed runs; higher line speed causes inner/outer wall roughness, flow lines, and degradation.
