DROFEN MACHINERY

DROFEN MACHINERY designs high-speed pen injector assembly lines and PP prefilled syringe (PFS) filling systems — concept through IQ/OQ/PQ validation.

Our pen platform: 160 PPM, cam-driven, 130-pallet architecture. Cam over servo because 16 servo axes exceed ±0.02mm positioning budget for Kistler force monitoring and Keyence LVDT verification. Every pen passes 100% inline inspection.

Equipment:
- Pre-assembly machine (8-13 components, vibratory feeding, RFID pallet tracking)
- Final assembly machine (2-cell: cartridge insertion + dose mechanism verification)
- PFS filling line (ISO 5 isolator, peristaltic/rotary piston dosing)

Engineering: 21 CFR Part 11 data integrity, Challenge Parts validation, cleanroom integration (ISO 7/5), full changeover for GLP-1, insulin, biologics.

On this channel: equipment demos, architecture comparisons, and technical white papers.
