Capping Head Ø54×50.6 for 29/25 Caps

This capping head is built for high-speed rotary capping equipment and is commonly used on production lines that run long hours without interruption. The part is made from high-quality stainless steel, and before leaving our workshop it goes through a special surface-strengthening process that helps it resist wear and maintain stable performance over time.

Its size follows the standard specification for 29/25 caps and 13.5 g PET preforms, which are widely used in beverage and daily-use product packaging. Thanks to precise machining and steady torque output, the head performs well on both new and older machines, even when the line is operated at higher speeds.

Features

Accurate & Reliable Operation

Each capping head is machined on our CNC equipment to ensure proper alignment and smooth rotation. This helps the cap engage correctly and reduces problems such as loose sealing or damaged threads.

Long Service Life

The combination of stainless steel and our surface treatment gives the part a strong resistance to friction, making it suitable for continuous operation in factories with heavy daily output.

Steady Torque During Capping

The internal structure is designed to help the cap tighten in a controlled way. This ensures a more uniform sealing effect across the entire batch.

Fits Many Machine Types

While this model is intended for high-speed rotary systems, we also manufacture capping heads for many other machines. Custom versions can easily be made with customer-supplied drawings or real samples.

Lower Maintenance Needs

Because the surface is treated for durability, the head requires less frequent replacement and reduces downtime on the line.

How It Works

When the machine rotates, the capping head turns with the turret and grips the cap. A preset torque is applied as the bottle moves through the station. The design helps control the tightening force so the cap is sealed properly without stressing the bottle neck.

Typical Applications

The head can be used in several industries, including:

Drinking water production

Carbonated and non-carbonated beverages

Edible oils

Household cleaning liquids

Personal-care products

Food and condiment packaging
