CraftOil Manual Capping Tool for 31.5×24 Bottle Caps

Description

The CraftOil manual capping tool (also called a manual capping key) is specifically designed for sealing aluminum screw caps with a standard size of 31.5×24 mm. This cap size is commonly used on bottles for cold-pressed oils, liqueurs, wines, balsams, syrups, and other liquids.

This tool is an indispensable assistant for small-scale production, artisan workshops, or even home-based craft operations producing limited batches of products.

Design and Working Principle

The tool is made from durable metal (usually steel with an anti-corrosion coating) and features a simple yet robust design.

It consists of:
• A handle body designed for a comfortable grip
• Serrated dies (rollers) that crimp the aluminum cap and form the thread
• An adjustment screw to set the compression force

How it works:

1. Place the cap on the bottle neck.

2. Position the capping tool over the cap.

3. Rotate the tool smoothly clockwise.

4. As the tool turns, the dies form the thread and crimp the cap skirt around the bottle neck.

5. Remove the tool – the capping is complete.

The result is a secure, evenly sealed cap that prevents leaks and preserves the taste and aroma of the product.
