Based on the previously focused background on the compliance and high-precision management of Moldflow hot runner cases in the medical consumables field, the following are some mainstream implementation cases in the industry:
Medical Syringe Injection Molding Case: A 32-cavity hot runner mold, optimized using Moldflow simulation with a symmetrical flow distribution structure, controls the melt residence time to within 15 seconds, with filling deviations in each cavity ≤2%, ensuring product dimensional consistency and eliminating dead corners.
Medical Infusion Catheter Connector Injection Molding Case: For sensitive PVC materials, simulation was used to identify dead corners in the runner, optimizing the full-circular transition runner to completely solve the problem of PVC thermal degradation and blackening, increasing the yield to over 99%.
Medical Indwelling Needle Base Injection Molding Case: Simulation optimization of the hot-tip nozzle layout reduced the melt residence time at the gate to less than 3 seconds, preventing white fog defects in transparent PC materials and meeting medical-grade cleanliness requirements.
Medical Nucleic Acid Test Kit Injection Molding Case: A single mold features an 48-cavity ultra-thin hot runner system, with simulated and optimized runner volume, reducing total melt volume by 40%. Multi-cavity balanced filling ensures no product warpage or deformation, making it suitable for large-scale mass production.
These cases all meet the stringent compliance requirements for medical consumables and represent mature, practical applications within the industry.
