Programmable Logic Controller (Siemens or equivalent) manages filling cycle, conveyor speed, pump actuation, and fault detection. All parameters are stored in non-volatile memory - cycle programs retained after power-off.

Colour touchscreen Human-Machine Interface (HMI) for fill volume setting, speed adjustment, batch count programming, and real-time production monitoring. Recipe storage for multiple vial sizes and fill volumes.

Programmable batch count target - machine stops automatically when preset vial count is reached. Batch records logged with date, time, fill volume, and count for GMP documentation.

Automatic fault detection for low air pressure, jam detection on conveyor, fill volume deviation alarm, and E-stop. Audible and visual alarm with fault code display on HMI.

Volumetric fill accuracy of ±1% RSD across the fill range - validated across fill volumes from 1 mL to 50 mL. Accuracy maintained over consecutive 1,000-vial production runs without operator intervention.

Precision-ground stainless steel piston pump delivers controlled, repeatable fill volumes per cycle. Piston stroke length is adjustable via the HMI - no mechanical tool change required for volume adjustment.

Spring-loaded anti-drip nozzle design prevents liquid drip between fills - critical for lyo vial filling where product contamination of the vial neck would compromise stopper seating during stoppering. Nozzle retracts cleanly after each fill cycle.

Machine design supports nitrogen gas overlay during filling - a requirement for oxygen-sensitive drug products. N₂ purge nozzle attachment available as option for filling under inert atmosphere.

Fill volume adjustment is performed via HMI parameter change and piston stroke reset - no mechanical disassembly, no tool change. Volume changeover from 5 mL to 10 mL in under 2 minutes.

Machine filling head is designed for integration with lyo stopper insertion - fills the vial, then positions for stopper placement at half-seated position (vented) before the vial enters the lyophilizer. Compatible with manual, semi-auto, and inline stoppering systems.

Fill level control is critical for lyophilization - overfill prevents product sublimation; underfill wastes product. The ±1% fill accuracy and anti-drip nozzle ensure consistent fill-to-headspace ratio across the entire batch.

Pneumatic vial positioning system holds each vial stationary under the nozzle during the fill cycle, then releases for conveyor advance. Eliminates fill-on-the-move errors and vial tip-over during high-viscosity product filling.

All product-wetted components - piston, cylinder, nozzle, tubing fittings, and liquid contact surfaces - are manufactured from SS316L pharmaceutical-grade stainless steel. Compliant with USP Class VI and EU GMP material requirements for pharmaceutical-contact parts.

Liquid pathway is designed for Clean-In-Place (CIP) and Sterilise-In-Place (SIP) procedures. Quick-release sanitary fittings allow rapid disassembly for manual cleaning between product changeovers.

Machine is CE marked, confirming compliance with EU Machinery Directive 2006/42/EC, Low Voltage Directive, and EMC Directive. CE Declaration of Conformity provided with every machine.

Accessible E-stop buttons on all four sides of the machine housing. E-stop cuts power to all moving parts instantly - conveyor, pump, and pneumatics. E-stop circuit hardwired independently of PLC for fail-safe operation.

Pressure switch on compressed air supply - if air pressure drops below 0.4 MPa, the machine halts filling and displays a low-pressure alarm. Prevents underfill from incomplete pneumatic actuation.

Factory Acceptance Test (FAT) protocol, IQ/OQ documentation templates, calibration certificate for fill volume accuracy, and user manual provided with each machine. Site Acceptance Test (SAT) support available.

A:Computer Numberical Control (CNC) machining is a manufacturing process in which pre-programmed computer softeare dictates the movement of fact`ory tools and machinery. The process can be used to control a range of complex machinery, from girnders and lathes to mills and CNC routers.
