ZONESUN ZS-FK4200V Automatic Aluminum Foil Lid Induction Sealing Machine

Overview

The ZONESUN ZS-FK4200V is a fully automatic continuous electromagnetic induction sealing machine designed for aluminum foil lid sealing on plastic bottles. Using high-frequency electromagnetic induction, it generates a super-audio current in the aluminum composite film at the bottle mouth, heating it to the set temperature to melt and bond the foil seal to the bottle rim — creating a hermetic, tamper-evident closure without physical contact. With an adjustable working height accommodating bottles from 10 to 380 mm and five selectable sensor head sizes covering cap diameters from φ15 mm to φ130 mm, the ZS-FK4200V adapts to a wide range of container formats on continuous production lines.

Important (110V version): The 110V variant requires connection to the supplied external transformer before operation. Bypassing the transformer may cause excessive voltage load and motor damage.

Technical Highlights

• Sealing Method: Electromagnetic induction (contactless, continuous)
• Applicable Cap Diameter: φ15–60 mm / φ20–70 mm / φ35–85 mm / φ50–120 mm / φ60–130 mm
• Adjustable Working Height: 10–380 mm (accommodates various bottle heights)
• Control Panel: Digital display with dual-section switches for independent zone control
• Power Supply: 110V (with external transformer) / 220V
• Scalability: Adaptable to various packaging line configurations

Key Features

• Contactless Electromagnetic Induction Sealing: High-frequency induction heats only the aluminum foil layer — no physical contact with the bottle or cap — eliminating contamination risk and mechanical wear on the sealing head while delivering consistent hermetic seals at line speed.
• Continuous Inline Operation: Bottles pass under the sensor head on a moving conveyor without stopping, enabling seamless integration into high-speed filling and capping lines without reducing overall line throughput.
• Five Cap Diameter Options (φ15–130 mm): Five sensor head size variants cover the full range of standard plastic bottle cap diameters — from small pharmaceutical vials to large-format food and chemical containers — with the correct head selected at order time.
• Wide Bottle Height Adjustment (10–380 mm): The sensor head column adjusts vertically to accommodate short vials through tall bottles without requiring separate machine configurations or custom fixtures.
• Dual-Section Digital Control Panel: Upgraded digital display with two independent zone switches allows operators to fine-tune power output for different foil thicknesses and cap materials, optimizing seal quality without trial-and-error.
• Tamper-Evident Hermetic Seal: Bonded aluminum foil seal provides visible tamper evidence and airtight closure, meeting food safety, pharmaceutical, and chemical packaging integrity requirements.
• Adaptable to Existing Packaging Lines: Compact overhead sensor design integrates with standard conveyor systems without requiring major line reconfiguration, reducing installation time and capital cost.
• Dual Voltage Availability (110V / 220V): Available in both voltage configurations for global deployment; 110V version ships with an external transformer to ensure correct operating voltage and motor protection.

Applications

• Food & Beverage Packaging: Aluminum foil induction sealing of cooking oil, vinegar, soy sauce, juice, dairy, and condiment bottles for tamper-evident retail packaging and extended shelf life.
• Pharmaceutical & Nutraceutical: Hermetic foil sealing of medicine bottles, supplement jars, and syrup containers for GMP-compliant tamper evidence and moisture barrier protection.
• Cosmetics & Personal Care: Foil sealing of shampoo, lotion, toner, and skincare bottles to prevent leakage during shipping and provide tamper-evident closure for retail.
• Chemical & Industrial Products: Sealing of lubricant, solvent, adhesive, and agricultural chemical bottles requiring leak-proof, tamper-evident closures for safe transport and storage.
• Household & Cleaning Products: Foil sealing of detergent, disinfectant, and fabric softener bottles for retail shelf presentation and spill prevention during distribution.
• Agricultural Inputs: Sealing of pesticide, fertilizer solution, and veterinary liquid bottles requiring robust tamper-evident foil closures for regulatory compliance and safe handling.
