A continuous induction sealer for 20-130mm caps is a machine that uses electromagnetic induction to create a tamper-evident, leak-proof seal by melting and bonding an aluminum foil liner to the bottle's opening. It is an automatic, high-speed process for continuous production lines in industries like pharmaceuticals, food, and cosmetics, providing a secure seal that prevents contamination and extends product shelf life. 

How it works

• Principle: The machine uses electromagnetic induction to generate instant, high heat.
• Process: As containers move on a conveyor belt, the electromagnetic coil heats an aluminum foil liner integrated into the cap.
• Sealing: The melted foil forms a secure, heat-sealed bond to the bottle's opening, creating a tamper-evident seal. 

Key features and specifications

• Sealing range: Works with cap diameters from 20 mm to 130 mm.
• Continuous operation: Designed for high-volume production lines, allowing for continuous sealing.
• Adjustable settings: Allows for adjustments to conveyor speed and power to optimize the seal for different container sizes and materials.
• User-friendly: Features an intuitive control panel for easy operation and monitoring.
• Power: Typically operates around 1.5 kW for efficient performance, according to this Toolsvilla listing. 

Applications

• Pharmaceuticals: Ensures sterility and tamper-evidence for medicines.
• Food and beverage: Seals sauces, juices, and other liquids to maintain freshness and prevent leaks.
• Cosmetics and personal care: Seals lotions, creams, and serums, building consumer trust.
• Other industries: Widely used for lubricants, pesticides, and other products requiring a secure, sealed package.
