Crown Capping Machine: Complete Guide for Bottle Sealing
Introduction
A Crown Capping Machine is a packaging machine used to seal bottles especially glass bottles with crown caps (metal caps with a corrugated edge). It ensures a tight and secure seal, protecting the contents from leakage, contamination, and loss of carbonation.
Crown capping is widely used in industries where product freshness and airtight sealing are critical, such as beverages and pharmaceuticals.
What is a Crown Capping Machine?
A crown capper is a closing machine designed to place a pre-formed metal crown cap over the mouth of a rigid container and securely crimp it onto the bottle neck. Using mechanical force, the machine presses the cap and folds its edges around the bottle lip, creating a strong, airtight, and tamper-evident seal.
How Does the Machine Work?
The working process includes:
Bottle Placement – Filled bottles are positioned manually or via conveyor
Cap Feeding – Crown caps are placed or fed automatically
Capping Process – The machine presses and crimps the cap onto the bottle
Sealing – A tight, secure seal is formed
Discharge – Sealed bottles move to the next stage
