1. "Special Treatment" for Molds in the Cleanroom
Independent Temperature Control System: Mold temperature control precision is maintained at ±0.5°C to prevent plastic degradation and particle generation caused by temperature fluctuations. For instance, in the production of medical infusion bags, keeping mold temperature fluctuations below 1°C can reduce extractables and leachables (E&L) in the product by 50%.
Regular Disinfection Protocol: After every 5,000 production cycles, molds undergo a dual "UV + Ozone" disinfection process (2 hours of UV irradiation and an ozone concentration of ≥50 ppm), achieving a microbial kill rate of >99.99%.
2. "Zero-Contamination" Control During Injection Molding
Positive-Pressure Dust Prevention Design: An airflow barrier (air velocity of 0.5 m/s) is established around the mold to prevent external dust from entering the mold cavity. Measurements show that this design reduces dust particles (≥0.5 μm) on the mold surface by 98%.
In-line Particle Monitoring: A laser particle counter is installed at the injection molding machine's discharge outlet to monitor impurities in the melt in real-time; the system automatically halts operation to clean the mold runners if the particle concentration exceeds 100 particles/m³.
