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.

No issues putting it together. Starts easily. Cuts extremely well. My first task with this machine was to cut the pieces of glasses, and it cut much better than the industrial units I am used to. I should mention that this automatic glass cutting machine does NOT require you to touch the work to start the cutting with CNC controller which makes it VERY easy to use. A great cutter for glass processing at a great price.

I was wary of purchasing a Chinese-made glass cutter off the internet, but the reviews convinced me to give it a try. Got this unit in 28 days. No trouble in assembly and parameter setting. I've tried it to cut glass plates for kitchenware and gotten the cleanest cuts. It's a powerful all-in-one machine for both loading and cutting. No regrets with the buying of this great automatic glass cutting machine.

The sheets and pieces glass cutting machine came in good condition. So far I've only used a handful of times, but not disappointed. It works great. I don't know why I didn't get this cutting equipment sooner. It cuts through 1/8 inch and 1/4 inch pieces glasses like butter. Smooth edges are difficult to achieve with glass cutter. Make sure to buy the extra accessories you needed when you make an order.
