Complete Manufacturing Process
01 NaCl Solution Preparation
Fully automated WFI-based sodium chloride solution preparation system. Stainless steel jacketed compounding vessel (200–2,000 L, configurable) with continuous stirring and temperature control (±0.5°C). Inline conductivity monitoring, pH adjustment, and 0.22 µm sterilizing-grade filtration ensure every batch meets USP <1>, EP 0193, and WHO TRS 961 specifications.
| WFI-Based | 0.22 µm Filtration | CIP/SIP |
02 Syringe Mold Development & Component Supply
In-house tooling division develops all injection molds for PP syringe components - barrel (3 ml / 5 ml / 10 ml), Luer-Lock tip cap, and plunger stopper. S136 stainless steel molds with 16–32 cavity configurations guarantee ≥1,000,000 shot service life. All components produced in ISO Class 7 cleanrooms from USP Class VI / ISO 10993-compliant medical-grade PP resin with 100% CMM dimensional inspection.
| S136 Steel | USP Class VI | ISO Class 7 |
03 Aseptic Saline Filling & Stoppering
Core filling station operates under ISO 5 (Class 100) unidirectional laminar airflow within an ISO 7 background cleanroom. Servo-driven ceramic pump filling system achieves ±0.5% fill accuracy at 220 syringes per minute. Integrated 100% in-process weight check (IPC) rejects any unit outside tolerance. Automated stoppering with force-feedback verification ensures complete stopper seating on every unit.
| ±0.5% Accuracy | ISO 5 Cleanroom | SAL 10⁻⁶ |
04 AI-Powered Light Inspection for PP Syringes
Polypropylene syringes present the most challenging inspection scenario in the industry - low optical clarity, conical shadow zones, and silicone oil droplets that mimic particulate matter. DROFEN's multi-spectral AI vision inspection system uses polarized LED illumination at multiple wavelengths, high-speed cameras (≥2,000 fps), and a deep-learning engine trained on 500,000+ PP syringe images. Detection accuracy reaches 99.5% for particles ≥50 µm with false rejection rates reduced by 40% versus rule-based systems.
| AI Vision | 99.5% Detection | USP <790> |
05 Plunger Rod Insertion & Serialization
Servo-electric actuators with force-displacement monitoring insert and verify every plunger rod assembly (5–20 N, ±0.5 N accuracy). Inline thermal transfer printer applies variable data at 200 labels per minute. 100% vision system verifies label presence, print quality, and barcode readability. GS1 DataMatrix and GS1-128 serialization supports EU FMD, India CDSCO, Saudi SFDA, and FDA DSCSA track-and-trace requirements.
| GS1 DataMatrix | EU FMD | CDSCO / SFDA |
06 High-Speed Pillow Packaging
Final station packages each labeled syringe into individual pillow packs at 220 packs per minute. Continuous film forming, optional nitrogen flushing (headspace O₂ <1%), and precision heat sealing (±1°C temperature control) ensure hermetic, shelf-stable packaging. 100% seal integrity verification and barcode scan with automatic reject diverter for any failed pack.

Core Technology
AI-Powered Light Inspection
for PP Syringes
The industry's most challenging inspection problem - solved. Polypropylene syringes have inherently low optical clarity, creating shadow zones that confuse conventional inspection systems. Our deep-learning classification engine, trained on over 500,000 PP syringe images, discriminates between true particulate contamination and silicone oil droplets with 99.5% accuracy.
