Feed Screw for 1–2 ml Ampoules in Pharmaceutical Lines
The feed screw for 1–2 ml ampoules is designed for controlled transport of glass ampoules between process stations in pharmaceutical equipment. The component provides synchronized container feeding during filling, dosing, capping, inspection, and packaging operations.
The screw geometry is specifically engineered for small ampoule formats, where positioning accuracy, vibration-free operation, and smooth container movement are critical.
📌 Stable Geometry and Smooth Container Transfer
The helical groove profile is developed according to the ampoule dimensions and production line speed. The feed screw geometry ensures:
- uniform spacing between ampoules
- stable container orientation
- elimination of misalignment during transport
- reduced impact loads
- smooth movement without jerking
The polished working surface prevents damage to glass ampoules and minimizes friction during transportation.
🛠️ CNC Manufacturing Technology
Production is carried out using high-precision CNC machining with subsequent inspection of geometry and helical profile parameters.
The manufacturing process includes:
- machining of the polymer blank
- formation of the helical groove
- machining of mounting elements
- feed pitch verification
- concentricity and runout inspection
- final surface polishing
Precision machining ensures seamless integration of the feed screw into the equipment transport system without additional modification.
✔️ Materials for Pharmaceutical Applications
The feed screws are manufactured from pharmaceutical-grade engineering polymers:
- POM (Delrin)
- UHMW-PE
The materials provide:
- high wear resistance
- dimensional stability
- low friction coefficient
- resistance to alcohols and disinfectant solutions
- compatibility with CIP/SIP processes
Each feed screw is individually manufactured according to ampoule dimensions, line productivity, equipment type, transport section geometry.
