With proper operation and routine maintenance,
the normal service life of our machines is 10 to 15 years, ensuring a high return on investment.

Our folder gluer equipment features:
1. Solid steel construction.
2. Versatility for various box types.
3. Modular design.
4. High-speed stability (up to 400 m/min).
5. Premium imported folder gluer parts.
6. Reliable remote troubleshooting services.

Yes.
When processing standard straight-line boxes,
both our YL and YZ series high-speed folder gluers can achieve a maximum line speed of 400 m/min.

Absolutely.
Our HL Series is a heavy-duty corrugated box gluing machine purpose-built for thick materials,
easily supporting five-layer corrugated boards up to 10 mm in thickness.

Yes.
Sinosun offer the YL-400PC-B, a specialized small box folder gluer proven to easily handle mini auto-lock bottom boxes for e-cigarette and cosmetic packaging.

For delicate boxes, we offer two solutions:
1. Feed the sheet with the glue flap contacting the belt using a 90-degree transfer.
2. Opt for a top-suction anti-scuff feeder to eliminate sheet-to-sheet friction.

Of course.
Our machines feature a modular design.
You can selectively add functions (like 4/6-corner devices or inline inspection) to your existing equipment later without purchasing an entirely new system.

The system supports all common packaging adhesives,
including white glue (PVAc), water-based glue, and hot melt glue.

Before starting up:
1. Perform a general inspection.
2. Fill the cleaned glue pot with suitable adhesive.
3. Connect the power and air supply, and verify the air pressure is stable.

Daily maintenance includes:
1. Using an air gun to blow away paper dust from the rollers.
2. Inspecting belts and support rod locks for wear, and replacing any severely deformed parts for folder gluer machine.

Never use highly corrosive solvents.
While the machine is stopped, use clean water or a dedicated belt cleaner,
and gently wipe the feeder belt with a slightly damp cloth.

To maintain the glue pot:
1. Regularly spray lubricant on roller surfaces.
2. Remove glue buildup.
3. Apply grease to oil holes.
4. Blow the tank dry and apply anti-rust lubricant after cleaning.

Frequently adjusted locking collars are considered consumable folder gluer machine parts.
Examples include feeder support rod collars, final folding hold-down roller collars,
and delivery section receiving wheel collars.

It’s very straightforward.
Our machines are designed for user-friendly maintenance.
Operators can generally replace belts independently, and we provide real-time video guidance if needed.

Apply anti-rust spray to the entire machine, loosen all belts to prevent tension deformation,
and cover the equipment with a dust sheet.

1. Check the alarm screen on the HMI.
2. Open the control cabinet to see if the inverter displays a fault code.
3. Disconnect the power, wait 30 seconds, and restart.

1. Check if the pulley is rotating. If it turns but the belt doesn’t, the belt is slipping—tighten it appropriately.
2. Check if the timing belt is broken and requires replacement with new folder gluer spare parts.

1. Check the feeder inverter for fault codes.
2. Power off and manually turn the feeder belt to ensure it rotates freely.
3. Verify the paper feeding settings on the control panel.

1. Verify motor insulation is intact.
2. Check for phase wires shorted to ground.
3. Inspect cable insulation for damage. 4. Reduce the starting load.

1. Inspect the proximity switch.
2. Ensure signal cable shielding is intact.
3. Check for loose wiring connections.
4. Replace the damaged sensor if necessary.

1. Check the photoelectric sensor on the glue pot.
2. Clean the sensor’s bottom surface.
3. Adjust the sensing range (5–8 cm).
4. Replace the sensor if it remains constantly lit.
