Ultra High-Speed, High-Precision 6-Head Liquid Filling and Rubber Stoppering Machine for Large-Scale Pharmaceutical and Injectable Lines

The Harsiddh Six Head Liquid Vial Filling Stoppering Machine is an industrial-grade, ultra-high-speed monoblock packaging system engineered for high-throughput sterile manufacturing. Built for large-scale pharmaceutical facilities, contract manufacturers, and biotech processing plants, this machine combines six synchronized volumetric dosing nozzles with automated rubber stoppering on a heavy-duty, continuous-indexing frame. Delivering speeds up to 180 vials per minute without compromising fill accuracy or sterile cleanroom integrity, it provides an ideal high-output solution with a compact footprint.

High-Performance Engineering for High-Volume Sterile Operations

In high-volume pharmaceutical production, scaling output while satisfying stringent WHO and US-FDA cGMP requirements demands robust, efficient machinery. The Six Head Liquid Vial Filling Stoppering Machine delivers speed and repeatability through its synchronized 6-nozzle diving bridge, dual-feed vibratory stopper delivery, and high-precision indexing platform.

By organizing liquid filling and rubber stoppering on a unified monoblock platform, the machine reduces transfer time between filling and sealing. This significantly lowers contamination risk and optimizes valuable cleanroom space compared to conventional multi-machine lines.

Step-by-Step Operational Workflow & Technical Anatomy

[ In-Feed Rotary Turntable ] → [ 6-Head Precision Liquid Dosing ] → [ Automated Stopper Placement ] → [ Outfeed Conveyor ]

1. In-Feed & Starwheel Indexing

Sterile vials are automatically fed from an in-feed rotary turntable onto an indexing starwheel mechanism. The starwheel holds six vials simultaneously, moving them beneath the filling station with smooth, non-vibrational motion to prevent tipping or bottle glass friction.

2. Six-Head Diving Liquid Filling

Six synchronized volumetric piston pumps (or multi-channel peristaltic pumps) dispense precise liquid volumes using sub-surface diving nozzles. The nozzles descend into the vial necks and gradually rise during dispensing to prevent air entrapment, splashing, or foaming on the vial rim.

3. Automatic Vibratory Rubber Stoppering

Rubber stoppers are sorted through high-capacity overhead vibratory bowls and delivered via precision-machined stainless steel chutes. Synchronized pick-and-place stoppering heads seat the rubber stoppers into the vial necks immediately after liquid dispensing.

4. Continuous Outfeed Discharge

Fully filled and stoppered vials are indexed out through the discharge starwheel onto the outfeed conveyor, feeding directly into downstream aluminum cap sealing and labeling units.

Salient Features

• Drip-Free Diving Nozzles: Positively driven diving nozzles ensure clean liquid cut-off with zero dripping, keeping vial shoulders completely clean for tight rubber sealing.
• Sanitary Tri-Clamp Connections: All liquid contact parts use sanitary tri-clamp fittings and mirror-polished SS 316L for rapid disassembly during Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) routines.
• Fast Tool-Less Changeovers: Quick-release starwheels and height-adjustable dosing bridges allow efficient changeovers across various vial dimensions (2 ml to 100 ml).
• AC Variable Frequency Drive (VFD): Stepless speed adjustment enables seamless synchronization with upstream washing/sterilization tunnels and downstream capping machinery.
• Safety Enclosure: Transparent shatterproof acrylic/glass safety doors with safety interlocks automatically pause machine operation if a door is opened during a run.
