Feed Screw for Pharmaceutical Equipment
The feed screw is used in filling, capping, inspection, dosing, and labeling systems where synchronized container transport without displacement or product damage is critically important.
The optimized helical profile geometry creates a stable container movement path between machine stations, eliminating jerks, misalignment, and uncontrolled flow interruptions.
The solution is suitable for high-speed pharmaceutical equipment handling glass ampoules, plastic vials, cartridges, and syringes.
🔧 Manufacturing Technology
Precision CNC Machining
Each feed screw is manufactured using high-precision CNC machining combined with multi-stage geometric inspection.
The production process includes:
- precision machining of the raw blank
- generation of the helical groove with controlled pitch
- machining of transition areas
- polishing of the working surface
- runout and concentricity inspection
Precise profile synchronization ensures reliable feed screw operation even on high-speed production lines with minimal process tolerances.
Surface and Geometry Control
Final surface finishing is performed to: Ra ≤ 0.4 µm
The polished surface:
- reduces friction coefficient
- prevents contamination buildup
- minimizes wear of mating components
- facilitates sanitary cleaning procedures
