Will excessive sealing speed affect the quality of the finished product? Let me explain.First, it depends on how fast you go. Many customers want the sealing speed as fast as possible, but honestly speaking, excessively fast sealing will definitely affect product quality.

The best result comes from matching the sealing speed with the line speed of the double glass production line.From our practical experience, around 20 meters per minute is the ideal and stable speed.

Why is too fast speed harmful?The sealant relies on pressure to fully fill the gap. If the speed is too high, the pressure cannot keep up, resulting in unfilled gaps and white lines. We have long-term customers with very strict quality standards — even a tiny white line is considered defective.

Therefore, I believe that excessively fast sealing speed will definitely reduce the quality of the final product.
