30–40 bottles/min PET Glass Plastic Screw Capping Machine

Plastic Screw Capping Machine Product Introduction 

The 30–40 bottles/min PET Glass Plastic Screw Capping Machine is designed for medium-speed automated production. It supports various bottle materials including PET, glass, and plastic, and handles different cap sizes with high precision.

Equipped with a pneumatic-electric capping head, the machine delivers uniform torque and reliable sealing to prevent leaks. The adjustable conveyor speed and capping height allow seamless integration into food, beverage, cosmetic, and chemical production lines. The compact stainless steel structure ensures long-term durability and easy maintenance.

Working Principle：

Bottles are conveyed into the capping area, where a pneumatic-electric screw capping head aligns with each bottle. The head applies controlled torque to tighten the cap precisely. Sensors monitor bottle position and torque to ensure uniform sealing, preventing over-tightening or leaks. Once capped, bottles continue down the conveyor for further processing.
