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.

Surprised at the quality of this compact Glass Loading Lifter Equipment when it arrived. Put it together in 30 minutes. Small in size and easy to move. I bought this unit to move the pieces of float glass. It is easy to use with automatic software and there are no issues so far. I have tried this loading and moving tool to move glasses sheets, and if necessary, I will try to move more types and pieces of glasses in the next week.

I thought I just bought this glass loading lifter equipment to upgrade my automation glass processing in commercial use. It could save you much more cost and time compared to handle moving tools.This equipment has been moving exactly as I expected. It is great to loading and unloading the edge of sheet glasses. I have moved over 100 Pcs glasses plates so far with no issues. Expect it to perform better in the future.

Considering LIJIANG Glass which is a famous glass machine brand, I bought one for my workshop last month. However, it was easy to setup and operate. I used it to move the jumbo pieces of float glass from this glass processing factory to others places. All the pieces of glass moves perfectly without secondly. Did great jobs with ease. I'm impressed with how well it loading and unloading with higher speed and accurate precision.
