Effect of bubbles and impurities on strength and sealing

During the production of aluminum profiles, if bubbles or impurities are present, this will significantly reduce the strength of the window. In addition, air bubbles can cause a lax seal, which can affect the window's sound and thermal insulation. If gaps appear when windows are closed, air and moisture may be introduced, causing discomfort in the indoor environment. Therefore, it is crucial to ensure the quality of aluminum profiles to ensure the overall performance of the window.
