Why do IG units have sealant leakage?

Sealant leakage is usually caused by incorrect sealant temperature or viscosity, poor spacer bending accuracy, glass size deviation, surface contamination, or unstable 2K sealing ratios.

How can I prevent sealant leakage in insulated glass units?

Maintain correct sealant temperature, ensure precise spacer bending, keep glass surfaces clean, use stable A/B sealant ratios, and consider using an automatic sealing robot for consistent quality.

Can equipment problems cause IG sealant leakage?

Yes. Butyl extruder temperature errors, 2K sealant mixing issues, worn nozzles, and inconsistent machine pressure can all lead to poor sealing performance and leakage.

Does manual sealing increase the risk of leakage?

Manual sealing often leads to uneven sealant lines and inconsistent corner filling. Using an automatic IG sealing robot significantly reduces leakage and improves product stability.

What is the best long-term solution for reducing IG sealant defects?

Investing in automated equipment—such as an IG sealing robot, automatic spacer bending machine, and calibrated 2K sealant pump—offers the most consistent and long-term solution to eliminate sealing problems.

Characteristics

Horizontal structure, simple operation. The machine frame adopts heavy-thickness metal + aluminum alloy to avoid being out of shape when working for a long time.

Witha stainless steel water sink and high-pressure pre-spraying (high-pressure pump) in loading ( in-feed), the rubber roller can pre-wash automatically to clean out the glass powder or scraps.

Brush: The top and bottom brushes are transmitted by 1 motor, respectively.

Water tank (with heater):

1 water tank is separated into 3 sections, 1 section for pre-wash, and the others for deep washing.

Blower: Low noise and vibration.

Conveying adopts a frequent converter, digital display, and convenient operation, which is good to connect with double edging line, hollow glass line, safety glass line, etc. Table rollers are adapted to superior rubber and are transmitted by a gear wheel, which ensures stable working.

Side covers, tanks, and any other water-touched material adopt stainless steel 304.

The washing and Drying section can be lifted to Max. 400MM by adjustment on the electrical board with 4 legs(corners), increasing through motors and the encoder.

3 pairs of air knives adopt an advanced technique device, large power, and quick air drying.

Electrical lifting structure

Ball screw(dia 40mm) + gear wheel + worm, no wheel-pin. Max lifting 400mm for machine maintenance.

Transmission gear

The transmission gear is made of high-quality 45 # steel quenched material, which is durable with low transmission noise, low load, stable work efficiency, and long service life.

Brush shaft head

The brush adopts a 35 diameter large shaft head, ensuring the stability and durability of the brush during the glass cleaning process.

Waterproof system

3 sections waterproof system with a silicon ring and a block board to avoid water from dropping into the bearing.

Transmission structure

The XPA belt-driven brush ensures the smoothness and durability of the brush during high-speed rotation. The gear motor ensures sufficient torque of the brush when cleaning thick glass, and will not cause the motor to jam due to insufficient torque caused by low speed under variable frequency conditions.

Patent design

Independently researched and developed a fixed sliding sleeve for the rubber roller in the cleaning room. This design allows the rubber roller to slide smoothly up and down when pressing the glass into the cleaning room, without getting stuck and damaging the glass due to swinging left and right. Greatly improves the qualification rate of glass during cleaning. This design solves the instability, practicality, and common problems of easily damaging glass that many domestic manufacturers process on cleaning room shelves.
