Re-engineering 24-Station PFS Filling Line to Eliminate Micro-Stoppages
Pre-filled syringe (PFS) filling and stoppering operations require extreme precision to avoid plunger tilt and glass flange fractures. This project study covers the overhaul of a 24-station nest transfer system. Challenges in Syringe Nest De-nesting Nest warpage caused gripper misalignment, resulting in frequent machine emergency stops and sterility breach alarms inside the RABS barrier. Vedax […]
Zero-Drip High-Viscosity Dosing System for Eye-Drop Suspensions
Ophthalmic suspensions containing polymers often form sticky droplets at nozzle tips during filling, creating exterior bottle neck contamination and cap sealing defects. Here is how Vedax solved the problem. Positive Pneumatic Shutoff Dispensing Needles Replacing open nozzles with internal needle-actuated positive shutoff tips eliminated droplet hang-up instantaneously upon dose completion. Viscosity-Matched Hydrodynamic Geometry The internal […]
Custom Anti-Scratch Starwheels for 400 BPM High-Speed Vial Line
A multinational injectable manufacturer was experiencing a 2.4% glass vial rejection rate due to scuffing and micro-fissures during high-speed transfer on a 400 bottles/minute line. Vedax re-engineered the complete infeed/outfeed handling assembly. Root Cause Analysis: Metal-on-Glass Friction Existing stainless steel transfer plates and rigid aluminum starwheels lacked elasticity during sudden line acceleration. High inertial impact […]
