Automatic Injectable Powder Filling with Rubber Stoppering Machine

Multipack Automatic Injectable Powder Filling with Rubber Stoppering Machine is designed for automated filling of injectable pharmaceutical powders into vials, followed by controlled rubber stopper placement. The integrated filling and stoppering system minimizes manual intervention and provides a synchronized solution for pharmaceutical vial processing.

The machine can be configured for sterile powder and injectable applications according to the product characteristics, vial dimensions, stopper specifications, required filling range and production capacity.

Automatic Injectable Powder Filling Machine

The machine combines a controlled powder dosing system with automatic vial handling and rubber stoppering. It is suitable for pharmaceutical manufacturers requiring a reliable solution for injectable powder filling and immediate vial closure.

Working Process

Vial Infeed → Vial Positioning → Powder Filling → Rubber Stopper Feeding → Stopper Placement → Stoppered Vial Discharge

The stoppered vials can then be transferred to downstream equipment for:

Aluminium Cap Feeding → Capping/Crimping → Inspection → Labeling → Coding → Cartoning

Injectable Powder Filling Technology

The powder dosing mechanism is selected according to the characteristics of the injectable powder, including:

• Filling dose
• Bulk density
• Flowability
• Particle size
• Moisture/hygroscopicity
• Electrostatic behavior
• Required filling accuracy
• Production capacity

For low-dose injectable powders, product trials are recommended to establish the appropriate dosing technology and achievable accuracy.

Automatic Rubber Stoppering System

After powder filling, rubber stoppers are automatically transferred to the vial and positioned over the vial opening.

The stoppering system can include:

• Automatic rubber stopper feeding
• Stopper orientation
• Controlled stopper placement
• Vial presence detection
• Stopper presence monitoring
• Missing-stopper rejection
• Controlled vial transfer to the capping station

The exact stopper handling system depends on the vial neck finish, stopper dimensions and closure design.

Key Features

• Automatic injectable powder filling
• Automatic rubber stoppering
• Controlled vial handling
• Product-specific powder dosing
• PLC + HMI control
• No Vial – No Fill
• Vial presence detection
• Stopper presence monitoring
• Automatic reject system
• SS316/SS316L product-contact parts
• Hygienic pharmaceutical construction
• Servo-controlled mechanisms where required
• Recipe management
• Adjustable filling parameters
• Suitable for integration with capping and crimping systems
• Suitable for automated pharmaceutical packaging lines

Applications

The machine is suitable for appropriate:

• Sterile injectable powders
• Dry powder injectable formulations
• Antibiotic powder products
• Pharmaceutical vial products
• Specialty sterile powder formulations

For sterile injectable production, sterility is achieved through the complete validated aseptic process and controlled manufacturing environment—not by the filling machine alone.

Technical Specifications

Actual filling accuracy and production capacity depend on product characteristics, filling dose, vial dimensions, stopper configuration and final machine design.

Pharmaceutical & GMP-Oriented Construction

For injectable pharmaceutical applications, the machine can be configured with:

• SS316L product-contact components
• Smooth and cleanable surfaces
• Hygienic product-contact design
• Controlled vial movement
• Automatic stopper handling
• Vial and stopper detection
• Machine safety interlocks
• Automated reject handling
• Integration provisions for suitable aseptic processing systems

Where required, the filling system can be designed for integration with RABS, isolator or other appropriate contamination-control arrangements as part of the customer’s overall aseptic processing strategy.

Complete Injectable Powder Filling Line

A typical integrated line can include:

Vial Washing → Sterilization/Depyrogenation → Injectable Powder Filling → Rubber Stoppering → Aluminium Cap Feeding → Crimping → Inspection → Labeling → Coding/Serialization → Cartoning

The actual configuration depends on the pharmaceutical product, vial system and manufacturing process.
