Aluminum Screw Capping Machine

Description :

Many customers inquire about Aluminum Screw Capping Machine, which stands for Roll On Pilfer Proof closure. Essentially, it’s an unthreaded aluminum shell that’s placed over the bottle neck and pressed down as thread forming wheels spin around it, shaping it to fit the existing threads of the bottle and locking ring. In essence, a Aluminum Screw Capping Machine resembles a chuck capper, but it doesn’t torque a cap, so there’s no need for a clutch mechanism. Aluminum Screw Capping Machine come in various configurations, from single-head to multiple-head high-speed rotary systems. The primary advantage of our capper machine is that it simultaneously seals the product while providing tamper-evident security. However, it can be costly to run multiple cap sizes, and the bottle’s neck and threads must be durable enough to withstand the pressure needed to form threads, typically made of glass or hard plastic.

The capper is an automated capping machine designed to securely tighten pilfer-proof caps onto various types of bottles such as wine, olive oil, and drink bottles. It is compatible with caps ranging from 18 to 34mm in diameter (customization available for different cap sizes). Its automatic operation not only saves labor but also reduces production errors.

This capping machine is well-suited for roll-press-sealing aluminum caps onto plastic, PET, and glass bottles. It employs a screw-press capping process, where the bottle undergoes rolling press action from hobs, with automatic feeding of bottles and caps, as well as removal of incorrectly placed caps. The resulting capped bottles boast stable sealing effects and convenient uncapping, effectively serving as a deterrent against counterfeiting and theft.

The containers are conveyed to the star wheel via a conveyor system. The star wheel, operating in an indexing mode for single-head cappers or continuous motion for multi-head cappers, transports the containers to the cap placement station and then to the closing head. At the closing head, the cap is tightened to the required torque. If the head operates under pressure, it presses the cap onto the bottle neck using a spring unit. The torque level can be adjusted using a magnetic clutch mechanism on the closing head.

Once the closing process is completed, the star wheel shifts the container to the next station for pressing the smaller black cap. Subsequently, the star wheel moves the container to the finished products conveyor for further processing.
