Automated Vial Stoppering and Capping Machine (12-Head)

High-Speed Servo-Driven Seal Integrity for Advanced Healthcare Solutions

Product Overview

In the critical final stages of packaging Life sciences formulations, securing an absolute, tamper-evident seal is paramount. The Lingyao Automated Vial Stoppering and Capping Machine is a high-capacity rotary platform designed to seamlessly integrate into your existing liquid packaging lines.

Engineered to process 50ml to 1000ml glass or rigid plastic bottles, this robust machine operates at an impressive speed of 100 to 300 bottles per minute (BPM). Equipped with a customizable 12-head rotary configuration, it effortlessly handles the delicate insertion of rubber stoppers followed by precision aluminum or composite capping, ensuring zero-contamination packaging for high-value Bioactive liquids.

The Cause: Seal Failure and Glass Breakage at High Speeds

Achieving perfect seal integrity at 300 BPM presents significant mechanical challenges. Traditional capping machines utilize rigid mechanical clutches that apply inconsistent torque. This either results in loose caps that compromise the sterility of oxygen-sensitive Healthcare solutions, or excessive downward pressure that fractures the glass bottlenecks, causing catastrophic line stoppages and product loss.

Furthermore, out-of-position rubber stoppers ("hanging plugs") are a common issue before the final aluminum cap is applied. If a machine fails to detect and correct a misaligned stopper, the resulting imperfect seal will lead to total batch rejection during rigorous quality control audits.

The Solution: Servo Torque Control and Smart Vision Detection

The Lingyao platform eliminates these risks through adaptive servo-engineering. Each of the 12 capping heads is independently controlled by an advanced servo motor. This provides programmable, highly precise torque control. The machine applies the exact rotational force required to secure the cap tightly while engaging a patented low-pressure cushioning system that prevents any downward impact on fragile glass.

To guarantee flawless stoppering, the machine features an optimized pre-plugging station that achieves a hanging plug pass rate of > 99%. Optional integration with an AI-Powered Vision Inspection system monitors every container in real-time, instantly flagging and rejecting any misaligned caps or microscopic glass defects without slowing down the primary workflow.

Specifications

Application Scenarios
