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.

This is a special Vertical Low-E Glass Film Delecting Machine for automatic insulating glass processing and you should buy it for a personalized glass processing machine for your custom business. The subsurface glass processing details in manufacturers are amazing. It's pricey but it was worth every penny to try one equipment purchase from LIJIANG Glass this trusted team. It paid for itself in less than three months.

I'm not sure I'll be able to handle this new insulating glass desiccant filling machine as a glass processing beginnner. It is portalbe as it look when we bought it back. Working with the molecular sieves filling and sealing the holes of insulating glass aluminum spacer strips products. Tested it with the insulated glass buytl extreder equipmnet at yesterday. Easy to use and I have to give this kit top marks given its performance and price tag.

I purchased this insulated glass production line how to videos and learning its pros and cons in advance. Equipment assembly was sort of easy with the instruction book. The operator software that comes with it is easy to use that. I have done a few tests for insulating glass pieces with some examples and a couple of my own creations. It worked well and resulted in smooth and clear patterns. So far it is worth under this price to purchase and keep it.
