Servo-Driven HSL-120 Prefilled Syringe Filling Line 12000 Pcs/Hour Delivering ±1% Volumetric Accuracy

• Servo-driven precision: four independent servo axes position the nest, filling needles, stopper inserter and cap press with a repeatability of 0.02 mm, eliminating the drift that mechanical cam systems develop after long production runs.
• Volumetric accuracy of ±1 percent: a closed-loop piston pump with in-line mass flow verification checks every fill and automatically rejects out-of-tolerance syringes into a dedicated reject chute, so no short or overfilled unit reaches the downstream line.
• 12,000 pieces per hour output: the parallel filling head carries up to twelve needles and fills an entire nest in a single stroke, delivering three to four times the throughput of a single-needle machine on the same floor space.
• Recipe-based format changeover: syringe size, fill volume, stopper depth and capping force are stored as digital recipes, so switching from a 1 ml long format to a 10 ml format takes under 20 minutes without tools.
• Low product loss: the positive displacement pump and closed transfer path leave less than 30 ml of residual product in the system per batch, which matters when a single batch of dermal filler is worth several thousand dollars.
• Audit-ready control system: a Siemens PLC with a 10 inch colour touchscreen logs every batch, alarm and parameter change with a user ID and timestamp, satisfying 21 CFR Part 11 style data integrity expectations.

The HSL-120 is deployed in aseptic filling suites for hyaluronic acid dermal fillers, botulinum toxin diluent, heparin and saline flush syringes, veterinary vaccines, insulin pens and dental composite delivery. Because the filling head can be configured with either a rotary piston pump or a peristaltic path, the same platform serves both viscous gel products and water-thin solutions, allowing a contract manufacturer to run several product families on one validated line. The machine integrates with upstream tray denesters and downstream labelling, inspection and blister packing modules through a standard handshake interface, and it can be placed inside an isolator or a restricted access barrier system when full barrier separation is required.

Each unit is assembled, wired and run for eight continuous hours with customer product or placebo before shipment, and the factory acceptance test report includes fill weight statistics, reject rate and a full input and output verification sheet. The machine is packed in a seaworthy plywood case with a vacuum moisture barrier, rust preventive coating on all bare stainless surfaces and shock indicators on the case panels. A twelve month warranty covers all mechanical and electrical components excluding consumables, and remote support through a secure VPN tunnel is available within 24 hours of a service request. Spare parts kits for the piston pumps, silicone tubing and stopper tooling are kept in stock for five years after delivery.
