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.

LIJIANG Glass invites glass processors, window and door manufacturers, and façade glass producers to meet our team at Glasstech Asia 2026. The exhibition will take place from November 10 to 12, 2026, at the Malaysia International Trade and Exhibition Centre (MITEC) in Kuala Lumpur. Find us at Booth I-06, listed in the official exhibitor directory under our Malaysian team, EAST GLAZ AUTOMATION SOUTH EAST ASIA SDN. BHD. Exhibition and Conference in Southeast Asia

Explore automated insulating glass production

Whether you are planning a new insulating glass unit (IGU) line or upgrading an existing one, our team can help you evaluate equipment around your glass sizes, unit configurations, and daily output targets. Discuss how to connect glass washing and drying, spacer frame placement, pressing with argon gas filling, and automatic sealing into a production workflow that fits your order mix.For manufacturers processing jumbo or stepped insulating glass, bring a few typical unit specifications. We can discuss how glass dimensions, pane offsets, and sealing requirements affect the choice of conveying and sealing equipment.

Plan your next glass processing project

LIJIANG Glass provides equipment for flat glass processing, including CNC glass cutting machines, glass washing machines, automatic insulating glass production lines, sealing robots, and glass handling systems. Our team can discuss how individual machines fit into your existing layout or how to plan equipment for a new factory. Visitors can also speak with our Malaysia team about installation, operator training, and after-sales support.
