JMA A90 sliding window aluminum extrusion profile is the crystallization of advanced technology. Starting from the strict screening of raw materials, each piece of aluminum alloy has undergone multiple testing procedures to ensure its pure composition and high quality. During the extrusion process, Jianmei uses high-precision molds and advanced extrusion equipment to perfectly shape the aluminum alloy under great pressure. This process not only ensures the accuracy of the profile size and achieves millimeter-level tolerance control, but also makes the microstructure inside the profile dense and uniform, thus giving the profile super strong mechanical properties.
The high quality sealing strips perfectly match the profiles, forming a tight sealing barrier when the window sash is closed. Each seal is like a loyal guard, ready to fight, effectively blocking the wind, rain, dust and noise from the outside.
The interior of the profile adopts an advanced thermal insulation broken bridge desi…
