Intro
Injectable pharmaceuticals, vaccines and lyophilized preparations are mostly packaged in glass vials, whose filling, rubber stoppering and sealing procedures are the most strictly regulated links under GMP guidelines. Even tiny contamination or inaccurate dosing will lead to batch product scrapping and hidden medication safety risks.
As a one-stop pharmaceutical machinery supplier, Shanghai Reliance Machinery has focused on the R&D and manufacturing of automatic vial filling and stoppering equipment for years. We deliver standalone machines and fully integrated turnkey production lines, covering bottle washing, depyrogenation, filling, stoppering, capping, visual inspection and end-of-line labeling. This article elaborates on our core equipment strengths, applicable scenarios and customized service advantages for vial packaging.
1. GMP-Compliant Aseptic Structure Design for Cleanroom Production
All parts in direct contact with liquid medicine adopt 316L medical-grade stainless steel, with mirror polishing and seamless welding to eliminate dead corners where residue and bacteria may accumulate.
- The whole machine reserves interfaces for Class A laminar flow hood installation, realizing fully enclosed aseptic operation from bottle feeding to finished product output, effectively blocking external microbial pollution.
- Transmission components are isolated with sealed protective covers to prevent metal abrasion debris from falling into the production area, fully meeting the sterile manufacturing requirements of injections, biological agents and vaccine products.
- Support CIP online cleaning and SIP online sterilization, greatly shortening line switchover time between different medicine batches and avoiding cross-contamination between formulas.
2. Dual Filling Modes to Meet Dosing Precision Requirements
We configure two mature metering filling systems to match different production needs:
2.1 Peristaltic Pump Filling
Ideal for small-batch trial production, laboratory R&D preparations and low-viscosity trace liquids. The pump tube is disposable and easy to replace, with no dead volume inside the pipeline, which is friendly for frequent formula switching and equipment sanitization.
2.2 Piston Metering Filling
Designed for large-scale mass production lines. The filling error is controlled within ±0.5%, ensuring consistent dosage of each vial. It stably handles water-based solvents, suspensions and moderately viscous medicinal liquids, effectively reducing defective products caused by overfilling or underfilling.
3. Vacuum Negative Pressure Stoppering Technology to Secure Product Shelf Life
Unlike simple mechanical pressing stoppering, our core vacuum stoppering station extracts air inside the vial before pressing the rubber stopper:
- Negative pressure eliminates residual air to prevent liquid medicine from oxidation and deterioration during long-term storage.
- Touchscreen digital adjustment of pressing depth and pressure avoids stopper tilting, popping out or missing placement. The qualified stoppering rate stays above 99.8%, laying a solid foundation for the subsequent aluminum cap crimping and labeling processes.
4. Three Equipment Configurations for Different Production Scales
① Monoblock Integrated Filling & Stoppering Machine
Bottle unscrambling, filling and stoppering are integrated on one compact unit. It occupies minimal workshop space, perfectly matching pilot workshops, new drug R&D labs and small pharmaceutical factories with low to medium output demands.
② Linear Continuous Filling Stoppering Line
Each process is arranged in a straight modular layout. It can be freely docked with upstream bottle washing & depyrogenation tunnels and downstream capping, inspection and labeling machines, forming a complete automatic packaging assembly line. It is convenient for later function expansion and equipment maintenance.
③ High-Speed Rotary Filling Stoppering Line
Adopts cam rotary indexing transmission structure, with production capacity up to hundreds of vials per minute. It supports 24-hour uninterrupted stable operation, customized for large pharmaceutical enterprises with high-volume standardized production orders.
5. Built-In Visual Inspection System for Full-Cycle Quality Control
Multiple detection modules are embedded as standard to realize automatic online rejection of non-conforming products:
- Empty bottle inspection: Automatically reject cracked, deformed or missing vials before filling to avoid equipment jamming.
- Liquid level checking: Camera recognition screens out vials with unqualified filling volume.
- Stopper defect detection: Identify missing, offset or loosely pressed stoppers and push waste products into designated bins in real time. All production data is recorded and stored to support batch traceability, which helps customers pass international regulatory audits such as GMP and FDA smoothly.
6. Turnkey Customization & Global Full-Lifecycle After-Sales Support
Beyond single filling and stoppering equipment, Shanghai Reliance Machinery provides holistic turnkey project services:
- Customize fixtures, molds and line layout according to vial specifications (2ml, 5ml, 10ml, 20ml and special sizes) and liquid physical properties.
- Offer overall planning for the entire production chain: Bottle Washing → Depyrogenation → Filling & Stoppering → Crimping → Visual Inspection → Labeling → Cartoning.
- Provide overseas on-site installation, commissioning and operator training; deliver long-term spare parts supply and remote online troubleshooting for clients worldwide.
Conclusion
Against the backdrop of increasingly stringent global pharmaceutical supervision, intelligent, sterile and traceable packaging equipment has become indispensable core hardware for pharmaceutical manufacturers.
Shanghai Reliance Machinery always centers on compliance, stability and customization to develop vial filling and packaging equipment. Whether you need pilot small-batch equipment or large automated production lines, we can tailor targeted machinery solutions to cut production costs, lower reject rates and standardize your pharmaceutical packaging workflow.
