High-Speed Automatic Induction Sealing Machine with Conveyor

High-Speed Automatic Induction Sealing Machine with Conveyor

The SUNAURA high-speed automatic induction sealing machine with conveyor is our flagship water-cooled production-line sealer. A 3000W water-cooled generator delivers stable output for all-day production across Φ20–150mm caps (optional ~180mm), riding on a heavy-duty integrated conveyor (load ≤50kg) at up to ~150 bottles/min.

Product Description

The SUNAURA high-speed automatic induction sealing machine with conveyor is the top of our range — a water-cooled production-line sealer built for serious volume. A 3000W water-cooled generator sustains stable, high output across all-day running, which is the defining advantage over air-cooled units: water removes heat continuously, so the machine has no thermal duty-cycle ceiling that forces it to pause between batches.

The included heavy-duty conveyor (load up to 50kg) integrates directly into a full bottling line, sitting after a capper and before a labeler. It covers a wide Φ20–150mm sealing range (up to ~180mm optional) across PET, glass, HDPE, and PP containers of many neck sizes, at speeds of 5–18 m/min (up to ~150 bottles/min). The stainless-steel enclosure suits hygienic pharmaceutical, beverage, food, and cosmetics production, and the transistor control circuit carries IP21 protection.

This is the machine production engineers specify when downtime is expensive and the line runs hard: pharmaceutical lines, beverage plants, food factories, and cosmetics manufacturers running high volumes. Every unit is CE certified and backed by a 12-month warranty and lifetime support from our Qingdao factory.

Application Industries

This flagship sealer targets high-volume production where continuous uptime and a wide neck range both matter.

Pharmaceutical

OTC medicines, syrups, and oral liquids — tamper-evident sealing required by FDA and GMP guidelines at high line speed.

Beverages

Water, soda, juice, and tea plants running fast bottling lines across PET and glass bottles.

Food Production

Sauces, condiments, edible oils, and dairy — high-volume hermetic seals that prevent leakage and extend shelf life.

Cosmetics

Lotions, shampoos, and personal-care lines — protects against leakage in shipping and preserves product freshness.

Chemicals

Industrial liquids and lubricants at scale — reliable, leak-proof sealing on high-throughput chemical lines.

Container Types

Seals PET, glass, HDPE, and PP containers across many neck sizes from Φ20 to 150mm (optional ~180mm).

How Induction Sealing Works

Induction sealing bonds an aluminum foil liner to the container mouth without contact. On this high-speed inline unit, the cycle is continuous and water-cooled:

  1. Capped containers feed inline under the head. Filled, capped bottles ride the heavy conveyor from the capper directly under the RF sealing head at line speed.
  2. 3000W field induces current in the foil. The water-cooled generator drives a high-frequency alternating magnetic field, inducing eddy currents that heat the aluminum foil almost instantly.
  3. Wax melts and film bonds to the rim. Heat melts the wax into the pulp board while the heat-activated film fuses to the container mouth.
  4. Foil seal remains after cap removal. When the consumer unscrews the cap, the pulp stays in the cap and the aluminum disc stays bonded to the mouth as tamper evidence.
  5. Water cooling sustains continuous output. Chilled water circulates through the generator and head, holding temperature steady so the line runs hour after hour without a thermal pause.

How to Choose the Right High-Speed Inline Sealer

This is the production flagship — choose it when uptime and throughput are the priority. Confirm the fit with these four checks:

  1. Confirm you need water cooling. If your line runs high-power for many hours a day, water cooling removes the duty-cycle limits of air-cooled units. If you run intermittent shifts, an air-cooled model may save on plumbing and cost.
  2. Match the neck range to your SKUs. At Φ20–150mm (optional ~180mm) it covers a wide mix. Send us your full container list so we confirm the head covers every neck size with margin.
  3. Verify line integration. Tell us the filler, capper, and labeler heights and belt direction. The heavy conveyor is designed to bolt between them; we spec the exact conveyor length and height before shipment.
  4. Plan the water supply. You need a chilled water supply (or we can recommend a compatible chiller) and a drain. Budget for this in your installation — it is the trade-off for true 24/7 high-power sealing.

Troubleshooting Guide — Common Issues & Solutions

Water-cooled production sealers are dependable, but high-volume lines can still show issues. Below are the most common problems on this model, their causes, and fixes. Always disconnect power before inspecting the sealing head.

  • Belt speed mismatched to filler; photo-eye blocked; bottle jam; guide gap wrong.
  • ProblemPossible CausesSolutions
    Weak or incomplete seal at line speedConveyor too fast for dwell time; head gap too large; low power; wrong liner.
    • Reduce conveyor speed and re-test seal strength.
    • Lower the head to a 2–5 mm gap above the cap.
    • Increase output in small increments, testing between steps.
    • Verify induction foil liners matched to container material.
    Over-temperature / water alarmLow water flow; blocked filter; chiller set too warm; kinked water line.
    • Check the water pump flow rate and open the supply valve fully.
    • Clean the inline water filter and flush the circuit.
    • Confirm the chiller set point and coolant temperature.
    • Inspect water hoses for kinks or blockages.
    No RF output / foil not heatingTripped breaker; loose head connector; non-induction liner; bottle off-center.
    • Reset the generator breaker and confirm steady power light.
    • Inspect the head cable and connector for looseness.
    • Use genuine induction foil liners, not pressure-sensitive inserts.
    • Align guides so each cap passes under the head center.
    Uneven seal across mixed neck sizesHead not re-set between SKUs; cap height varies; liner mis-seated.
    • Re-adjust head height and power when switching SKUs.
    • Keep fill level consistent so cap height does not vary.
    • Verify capping torque is uniform across all caps.
    • Confirm liners lie flat and centered in every cap.
    Conveyor / line synchronization issues
    • Match conveyor speed to the upstream filler output.
    • Clean the sensor lens and re-align to cap midpoint.
    • Clear any jam and inspect for broken glass or plastic.
    • Set side guides 2 mm wider than the widest container.
    Arcing / sparking near the headMetal objects near head; protruding foil edge; cracked insulator; excessive power for small caps.
    • Remove all metal tools within 30 cm of the head.
    • Ensure no foil edge protrudes above the cap rim.
    • Inspect the Teflon insulator cover; replace if cracked.
    • Reduce power for small caps — lower settings may still fully seal.

    Frequently Asked Questions

    Why is this model water-cooled instead of air-cooled?

    Water cooling is the defining feature of this production flagship. It removes heat continuously from the 3000W generator and head, so the machine runs at high power all day without the thermal duty-cycle pauses that air-cooled units need. That is why pharmaceutical lines, beverage plants, and food factories running high volumes choose it.

    How fast is the conveyor and what output can I expect?

    The conveyor runs at 5–18 m/min, translating to up to roughly 150 bottles per minute depending on neck size and material. Smaller necks run faster; wider lids run slightly slower for full foil heating. The heavy-duty belt carries loads up to 50kg so filled bottles feed steadily into the line.

    What neck sizes and containers does it seal?

    It covers Φ20–150mm as standard, with an option up to ~180mm, across PET, glass, HDPE, and PP containers up to 400mm tall. That wide range means one machine can serve many SKUs. Send us your full container list and we will confirm the head configuration.

    What do I need on-site for the water cooling?

    You need a chilled water supply (or we can recommend a compatible chiller) and a drain, plus a 220/110V power supply and a level floor. We ship the water hoses and connections with the machine and guide your installer on the setup. This plumbing is the trade-off you accept for true 24/7 high-power operation.

    Can it integrate with my existing filler, capper, and labeler?

    Yes. The machine is built for full-line integration. Tell us the heights, belt speed, and direction of your upstream and downstream machines — we spec the conveyor length, height, and interface so it slots in seamlessly. Standard models ship in 7–15 days; custom line integration in 20–30 days, backed by a 12-month warranty.
