Products Description
⚙️ I. Mechanical Structure Advantages
Ultra-Precision Clamping System
Micron-level clamping accuracy (±0.3%): Direct-pressure mechanism with high-rigidity platens eliminates flash on ultra-thin floss (Ø0.3~0.7mm), extends mold life by 30%.
Zero-inertia injection unit: Linear motor drive achieves ≤0.1s response, supporting 100+ cavity micro-molding.
Medical-Grade Clean Design
Fully enclosed dust-free guides: Stainless steel columns + IP67 seals block contaminants, compliant with FDA/GMP standards.
Tool-free quick-change: Mold and barrel zones allow full sanitization in ≤15 minutes.
⛽ II. Hydraulic System Advantages
Nanoscale Flow Control
Servo direct-drive pump: Flow fluctuation ≤±0.05%, enables 0.01g micro-dosing for floss diameter tolerance (±0.02mm).
Piezoelectric proportional valves: 5ms response enables 8-stage filling, preventing HMW-PE/PP melt fracture.
Aseptic Hydraulic Environment
USP Class VI hydraulic oil: Eliminates toxic migration risks.
Vacuum-sealed circuits: Dual FKM seals + negative pressure design ensure zero oil mist.
🔩 III. Screw & Barrel Design Advantages
Ultra-Low Shear Plastication
Ultra-low compression screw (1.2~1.4:1): Shallow flights (H/D=18~22) reduce shear heat, preserving PE/PP molecular integrity for floss flexibility.
Two-stage mixing: Barrier section separates unmelted particles; pin section homogenizes melt, eliminating "gel spots".
Medical-Grade Surface Treatment
Mirror-polished barrel (Ra≤0.05μm): Electropolished interior prevents residue, meeting Class 100,000 cleanliness.
Plasma-coated screw: AlCrN coating (HV3500) offers 5x higher wear resistance vs. nitrided screws (>5 million cycles).
Smart Temperature Control
8 independent zones: ±0.3°C PID control adapts to low-T processing (PE:160~180°C), preventing discoloration.
Electromagnetic heating: 60% less energy than band heaters, 8°C/s ramp rate, 50% faster material purge.
✨ IV. Floss-Specific Optimizations
Micro-tension in-line inspection: Laser gauges (0.01mm accuracy) monitor diameter with real-time process compensation.
Oxygen-free molding: Nitrogen purging (<100ppm O₂) prevents polymer oxidation embrittlement.
High-speed handling: Delta robot + vision achieves ≤3s cycle time, yield rate ≥99.8%.
