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.

Achieves New Efficiency Milestone with Laminating Line Speed Upgrade...

2 min read

In today’s highly competitive glass processing industry, production efficiency and operational stability have become key factors for manufacturers seeking sustainable growth. Recently, Jiangyin Longxiang successfully completed a laminating machine speed upgrade, achieving a significant improvement in production performance and daily output.

Faster Production, Greater Efficiency

After the optimization and upgrade, the laminating line now operates approximately 10 seconds faster per glass while maintaining stable and reliable performance throughout continuous production. This improvement enables the customer to achieve an average stable output of around 700 pieces per shift, greatly enhancing overall manufacturing efficiency.

The successful upgrade not only shortens production cycles but also helps reduce downtime and improve workflow coordination within the factory.

Stable Operation for Long-Term Production

For glass manufacturers, speed alone is not enough. Stability and consistency are equally important in ensuring product quality and reducing operational risks. The upgraded laminating machine demonstrates excellent operational stability during high-speed production, allowing the customer to maintain smooth and efficient manufacturing processes.

This achievement reflects the growing demand for intelligent and high-efficiency glass processing equipment in modern factories.

Supporting Smarter Glass Manufacturing

As glass manufacturers continue to pursue automation and lean production, equipment upgrades are becoming an effective way to increase competitiveness without investing in entirely new production lines.

The LIJIANG's Jiangyin Longxiang project once again demonstrates how optimized laminating technology can help customers:

Improve production efficiency

Increase daily output

Reduce production bottlenecks

Maintain stable product quality

Enhance factory automation levels

At LIJIANG Glass Machinery, we remain committed to delivering reliable and efficient glass processing solutions for customers worldwide.
