Horseshoe Folding vs. Heat Sealing: Why Metal Tubes Need Specialized Equipment
When it comes to tube filling and sealing, one size does not fit all. Plastic tubes and laminated tubes are typically sealed using heat, which melts the tube material to create a bond. Aluminum tubes, however, require a completely different approach: mechanical folding.
The JGF-B semi-automatic metal tube fill and fold tail machine is purpose-built for this application, employing an advanced horseshoe folding mechanism that creates a secure, leak-proof seal.
Why Heat Sealing Doesn't Work for Aluminum:
Aluminum is a metal conductor that disperses heat quickly. Attempting to heat-seal an aluminum tube would require extremely high temperatures that could damage the tube's coating or the product inside. Instead, aluminum tubes are sealed by folding the tail end into a tight, interlocking closure.
The Horseshoe Folding Advantage:
The horseshoe mechanism is considered the most advanced folding technology available. It performs a direct, multi-step fold that:
Aligns with the Tube Seam: Aluminum tubes have a seam where the body is joined. Proper alignment of this seam with the fold is critical for seal integrity.
Applies Consistent Pressure: The mechanism applies uniform pressure across the fold, preventing weak spots.
Creates a Hermetic Seal: The resulting fold is tight and secure, preventing leakage.
Solving the Leakage Problem:
Tail leakage is a common problem in metal tube packaging. The JGF-B's horseshoe mechanism directly addresses this by creating a clean, consistent fold that prevents the common fault of leaking at the tail after sealing.
