Reinforcement is specified
Your shipping case specification calls for taped vertical corners in addition to the main flap closure.

Fully Automatic Four Corner Sealing Machine
Configure four-corner taping around your verified carton range, tape specification, conveyor interface, line speed and acceptance criteria—not a generic catalog promise.
Four vertical cornersPhotoelectric cycleBatch-size adjustmentLine integration
Final performance depends on the approved cartons, tape, adjustment range, upstream presentation, utilities and FAT conditions.
Selection boundary
When Four-Corner Sealing Is the Right Project Route
Short answer: choose a four-corner sealer when the four vertical carton corners require additional tape reinforcement after the primary top-and-bottom closure. Confirm the exact carton construction, tape, presentation and acceptance test before treating catalog speed as usable output.
The sealing station must be automated
Upstream cartons arrive closed, consistently oriented and ready for a controlled photoelectric sealing cycle.
Multiple carton sizes are planned
Your team can define the full batch-size range and the changeover method to be demonstrated during FAT.
Random-size operation
Do not assume automatic random-size adjustment. State whether cartons run in batches or arrive in mixed dimensions.
Board and tape compatibility
Supply representative corrugated cases and the intended tape so adhesion, corner condition and tape length can be tested.
Only top and bottom closure is required
A standard automatic case sealing machine may be the simpler project boundary.
Controlled sealing sequence
How the HIJ-5050 Four-Corner Sealing Cycle Works
The usable cycle begins with a stable, closed carton and ends with an accepted reinforced case. Each station should be checked with the final board, tape and upstream presentation.
01
Detect the carton
Photoelectric sensing identifies the incoming case and initiates the configured automatic sequence.
02
Center and grip
The side-belt transport stabilizes the carton and controls its path through the sealing station.
03
Apply corner tape
The configured taping mechanism applies adhesive tape to the four vertical carton corners.
04
Discharge and verify
The sealed case transfers downstream for inspection, weighing, strapping, palletizing or other agreed handling.
Do not size the station from conveyor speed alone
Carton length, spacing, tape cycle, presentation stability, rejects and downstream stops determine accepted cases per minute.

Machine-route comparison
Four-Corner Sealer vs Standard Top-and-Bottom Sealer
The correct route depends on the required closure pattern. Do not add a four-corner station unless the case specification and distribution risk justify it.
| Decision point | Four-corner sealing route | Standard sealing route |
|---|---|---|
| Primary purpose | Reinforce the four vertical carton corners with tape | Close the top and bottom carton flaps |
| Starting carton state | Closed and consistently presented case | Case ready for primary flap closure |
| Best fit | Projects with a defined corner-reinforcement requirement | Projects where primary top/bottom closure is sufficient |
| Key samples | Final case, product load and selected tape | Final case, flap condition and selected tape |
| Acceptance focus | Corner coverage, tape alignment, adhesion and case transfer | Flap closure, centerline alignment, adhesion and transfer |
| Project risk | Adding complexity without a documented reinforcement need | Leaving an unmet corner-reinforcement requirement |
End-of-line integration
Calculate Accepted Output Across the Complete Case Line
The four-corner sealer cannot deliver more good cases than the slowest confirmed upstream, sealing or downstream stage.
Accepted cases/min
= minimum of upstream case supply, stable sealing cycle and downstream capacity × agreed acceptance rate
State carton size, pitch, stops, changeovers, accumulation and reject handling in the test basis.

- Mechanical conveyor height and transfer gap
- Electrical ready, run, stop and fault signals
- Accumulation and blocked-line behavior

FAT and acceptance
Prove the Final Carton, Tape and Line Behavior Before Shipment
The FAT should show repeatable sealing under the agreed operating window and preserve enough evidence for the buyer’s technical file.

Validation boundary
HIJ can supply machine documents and agreed FAT evidence to support the customer’s qualification process. Site installation, operating qualification, product-specific procedures and release decisions remain under the customer’s quality system.
Frequently asked questions
Four Corner Sealing Machine FAQ
What is a fully automatic four corner sealing machine?
It is an end-of-line carton sealer that automatically applies adhesive tape to the four vertical carton corners. The HIJ-5050 uses a photoelectric-controlled cycle and side-belt transport; final suitability depends on the approved carton, tape and line interface.
How is it different from a standard case sealer?
A standard case sealer normally closes the top and bottom flaps. A four-corner sealing machine adds tape reinforcement to the four vertical corners after the primary closure. Choose the route from the required case specification rather than from machine name alone.
What carton sizes are published for the HIJ-5050?
The current published range is 280 × 200 × 180 mm to 700 × 500 × 500 mm (L × W × H). Supply the complete SKU matrix and representative filled cases so tolerance, stability and changeover can be verified.
How fast can the HIJ-5050 run?
The published conveyor-speed reference is up to 20 m/min. Accepted cases per minute still depend on carton length, pitch, sealing cycle, presentation, rejects and downstream availability.
Which tape widths are listed?
The current published tape-width options are 48, 60 and 72 mm. Confirm the tape backing, adhesive, roll dimensions, supplier reference and acceptance criteria before quotation and FAT.
What information is required for an accurate quotation?
Send carton drawings and samples, filled case weight, tape specification, required good cases per minute, size-change pattern, power and air standard, conveyor height, line signals and the required FAT evidence.
