30-40 bottles/min PET & Plastic Bottle Servo Capping Machine

Capping Machine Product Introduction 

The 30-40 bottles/min PET & Plastic Bottle Servo Capping Machine is a versatile solution for liquid bottle production, designed to handle PET and various plastic bottle types efficiently. Equipped with a servo motor-driven screw capping system, it ensures precise torque control for consistent sealing without damaging caps or bottles. The automatic bottle positioning and cap feeding system improve operational efficiency while minimizing human intervention. Its durable stainless steel construction and hygienic design make it suitable for food, beverage, cosmetic, and household chemical products. The machine easily integrates into existing production lines, working seamlessly with filling, labeling, and packaging equipment to create a fully automated workflow.

Working Principle：

Bottles enter the machine via a conveyor and are stabilized by positioning guides. Caps are fed automatically from the feeder and aligned with the bottle mouth. The servo motor-driven screw capping head rotates the caps with controlled torque, ensuring tight and uniform sealing. Once capped, bottles continue to the next production stage for labeling or packaging, enabling a fully continuous automated process.
