Raghav heavy duty Crown corking machine

Overview

A heavy-duty crown corking machine (manual benchtop bottle capper) is a robust mechanical device engineered to crimp metallic crown caps tightly onto glass bottles, creating an airtight, leak-proof seal.

The model shown features a heavy cast-iron base, an ergonomic mechanical lever, and a magnetic crimping head designed for high-durability batch bottling operations.

Key Components & Construction
Ergonomic Long Operating Lever: A heavy-duty curved handle that provides high mechanical advantage, allowing smooth downward pressure with minimal physical effort.

Magnetic Capping / Crimping Head: Fitted with a internal magnet that holds the crown cap in place before crimping, ensuring precise alignment over the bottle neck.

Heavy Cast-Iron Base: Provides a low center of gravity and maximum stability during downward pressing. Includes mounting holes to bolt the machine securely to a workbench.

Adjustable Bottle Centering Stop: Rear guides mounted on the base platform keep the bottle perfectly aligned under the capping head to prevent tilting or glass breakage.

Chrome-Plated Support Pillar: A solid steel vertical column housing the height-adjustment mechanism to accommodate different glass bottle heights (e.g., 200 ml, 330 ml, 500 ml, or 750 ml).

Working Principle
Cap Placement: A metal crown cap is inserted into the magnetic capping die, where it stays suspended automatically.

Bottle Positioning: The filled glass bottle is placed on the base pad, pushing back against the rear centering guides for alignment.

Downward Lever Press: Pulling the top handle downward drives the crimping head onto the bottle neck.

Mechanical Crimp: The hardened steel bell forces the flared edges of the crown cap inward around the glass locking ring, creating an airtight pressure seal.
