High Speed Ampoule Filling Machine for Continuous Washing Drying Filling and Sealing Production

This high speed ampoule filling machine is a continuous production line rated up to 15,000 pcs/h, combining washing, drying, filling and flame sealing stations on one synchronized frame. It targets large-volume manufacturers where output per hour directly determines capacity expansion cost. Every station is driven by independent servo motors synchronized through a master PLC, so speed increases do not degrade filling accuracy.

Growing market demand forces injectable producers to add capacity, but buying a second medium-speed line doubles floor space, staffing and validation cost. Simply speeding up existing equipment fails because washing dwell time and sealing residence time cannot be shortened without compromising quality. The result is a capacity bottleneck at the filling step while washing and sealing stations idle.

Conventional machines use one main motor with mechanical cam shafts, so all stations run at the same fixed ratio. Raising line speed shortens the time ampoules spend under washing nozzles and in the sealing flame, causing incomplete cleaning and weak seals. Operators compensate by slowing the whole line, which defeats the purpose of the upgrade.

This machine uses independent servo drives for the washing rotor, drying tunnel, filling pumps and sealing burners, all synchronized by the PLC. Washing water pressure and nozzle count are sized so that cleaning completes within the shorter cycle, and sealing burners use pre-mixed gas with forced air cooling to fuse the glass neck in under one second. The result is 15,000 pcs/h with the same ±0.5% accuracy and seal strength as a medium-speed line.

• 15,000 pcs/h output: 12-head filling turret with servo-driven ceramic pumps keeps pace at top speed
• Independent servo stations: washing, drying, filling and sealing run at individually optimized speeds
• High-efficiency washing rotor: 36 washing stations with 0.2 MPa jet pressure complete cleaning in the short cycle
• Fast flame sealing: pre-mixed gas burners fuse necks in under 1 second with forced-air cooling
• Automatic rejection: in-line check-weighing rejects underfilled ampoules without stopping the line
• Low noise operation: enclosed cam boxes and balanced rotors keep noise below 78 dB(A)

This line fits large pharmaceutical groups and CMOs producing high-volume basic injectables such as saline, glucose, WFI and multivitamins in ampoules. A single line replaces two medium-speed machines, reducing cleanroom area by roughly 35% and operator headcount per million units by half. It is also the preferred platform for seasonal products where manufacturers must compress annual output into a few months.

The machine handles standard 1–20ml ampoules and can be configured for non-cylindrical or low-profile ampoules used in specific markets.

Confirm your actual annual volume first: 15,000 pcs/h translates to about 90 million units per year on two shifts, so smaller producers should not pay for unused speed. Second, check ampoule supply quality, because high speed amplifies the effect of dimensional variation; we recommend requesting ampoule tolerance data from your glass supplier. Third, verify that your downstream inspection and packaging lines can absorb 15,000 pcs/h, otherwise the filling line will starve the line downstream. Finally, request a factory acceptance test at full speed with your own ampoules before shipment.

Q: Does higher speed reduce sealing quality?

No. The sealing station uses pre-mixed gas burners with a controlled flame profile and forced-air cooling, completing fusion in under one second. Seal strength is verified by a leak test sample taken every 30 minutes; typical rejection rates stay below 0.3%.

Q: What ampoule sizes can run at full speed?

Full 15,000 pcs/h is achievable for 1–10ml ampoules. For 20ml ampoules, output is typically 10,000–12,000 pcs/h because of the longer sealing residence time required for thicker glass.

Q: How long does a size changeover take on this high speed line?

Approximately 40 minutes, including star wheel and nozzle replacement. The servo stations re-synchronize automatically through the PLC after the new recipe is loaded.

Q: Can the line be integrated with an existing sterilizing tunnel?

Yes. The drying module can be replaced by a dry-heat sterilizing tunnel, or the line can be coupled to your existing tunnel through a synchronized transfer star wheel.

Every machine is test-run with water and dummy ampoules for 72 hours before packing, and a sealed calibration report is shipped with the unit. The machine is wrapped in anti-rust film and secured in an export-grade wooden case with foam inserts, suitable for sea or air freight. We supply CE, GMP and ISO 9001 documentation, a 12-month warranty on parts, and lifetime remote technical support. On-site installation, operator training and IQ/OQ/PQ validation assistance are available on request.
