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 Vertical Glass Washing and Drying Machine when it arrived. Put it together in 30 minutes by videos-support. I bought this unit to washing the float glass. It is easy to use with an automatic software and there are no issues so far. I have tried this type of LJLQ-2000 Vertical Glass Washing and Drying Machine to wash more float glass and it resulted in clear and smooth surface without washing and drying in seconds. I will try to wash more types of glass in the next week.

LJLQ-2000 Vertikale Glaswasch- und Trockenmaschine

I purchased this type of LJLQ-2500 Vertical Glass Washing and Drying Machine after researching how to videos and learning its pros and cons in advance. Assembly was sort of easy with the instruction book. The software that comes with it is easy to use. I have done a few tests for float glass washing and drying with some examples and a couple of my own products. A great glass washing machine for anyone with intuition and patience on custom personalized firearms. So far it is worth the money.

LJLQ-2500 Vertikale Glaswasch- und Trockenmaschine

This type of JNLJ-2500 Horizontal Glass Washing and Drying Machine arrived in perfect condition with a long-term shipping. A well made machine with great quality control. All the parts are well built, tight and balanced. The bed frame is heavy duty with cast iron structure, which make it more stable to work. The variable speed of washing processing works very well, and the automatic speed control system is easy to use, and no human intervention required. Worth every penny from this purchase.
