In the field of building profiles, aluminum-plastic co-extruded profiles stand out with excellent strength performance and are highly favored by the market. Liaoning MOHAN New Material Co., Ltd. focuses on the research and development and production of aluminum-plastic co-extruded profiles, the next in-depth analysis of its unique structure for you to explore the mystery of strength.

First, aluminum alloy skeleton to lay a rigid foundation

Aluminum-plastic co-extruded profiles use aluminum alloy profiles as the supporting skeleton. Aluminum alloy has the characteristics of low density and high strength, and its yield strength, tensile strength and other mechanical property indexes are excellent, providing a basic rigidity guarantee for the profile. Compared with pure plastic profiles, the aluminum alloy skeleton significantly improves the profile's bending and tensile resistance, effectively preventing the profile from deformation and fracture during use.

Second, dovetail groove structure innovation to enhance wind pressure resistance

In the aluminum co-extruded profile aluminum liner design, dovetail groove structure can be called a major innovation highlights. This structural design can greatly improve the moment of inertia of the aluminum liner in the direction of wind pressure and deformation resistance under the premise of a small increase in the weight of the aluminum liner. Tests have shown that the use of the dovetail groove structure increases the moment of inertia by about 20% compared to a normal aluminum alloy structure (without dovetail groove). This increase in the moment of inertia means a material savings of 15 - 25% for the same wind pressure requirement. For example, in one comparison test, the moment of inertia Iy = 77,760 without a dovetailed liner versus 86,319 with a dovetailed liner, an increase of 11%, and in another test, the moment of inertia Iy = 60,686 without a dovetailed liner versus 76,189 with a dovetailed liner, an increase of 25%. It can be seen that the dovetail groove structure not only optimizes the material properties, but also realizes the efficient use of resources.

Third, tightly composite aluminum-plastic integrated structure

Aluminum-plastic co-extruded profiles through a special process, the thickness of about 4mm of the surface of the rigid core foam plastic tightly composite on the surface of the aluminum liner, so that the inner metal and the outer plastic perfect combination of one. This integrated structure eliminates the gaps and weak points that may exist in the traditional splicing method, and greatly enhances the overall structural stability of the profile. When impacted by external forces, the aluminum alloy skeleton and the outer plastic layer are subjected to forces in concert with each other, the aluminum alloy bears the main tensile and bending stresses, while the outer plastic layer buffers and disperses the impact forces, and the two are closely coordinated to jointly enhance the strength and impact resistance of the profile.

Fourth, scientific corner and center stile connection design

Corner connection: aluminum-plastic co-extruded door and window corners usually use 45° connection process. First cut the end of the profile into 45 ° angle, insert the special aluminum corner code, and then put into the improved welding machine to make the plastic welding molding, and finally use the screws to connect the profile with the corner code as a whole. This process realizes the corner of the plastic completely sealed, aluminum lining part of the formation of a closed-loop connection, greatly improving the strength of the corner, and effectively enhance the wind pressure into the window, anti-deformation ability.

Middle stile connection: the middle stile material is cut into straight material (90°) according to the size, and the steps are processed by special middle stile milling machine, so that it is connected with the frame groove, and then the middle stile material is firmly connected with the frame material through the special connecting parts (aluminum parts) and screws. This connection ensures the reliability of the connection between the center stile and the frame material, and further improves the structural strength and stability of the whole window.

To sum up, the aluminum-plastic co-extruded profiles, with the unique structure of aluminum alloy skeleton, dovetail groove structure, aluminum-plastic integrated composite, and scientific connection design, show advantages in strength that surpass the counterparts. Liaoning MOHAN New Material Co., Ltd. continues to deepen the technological innovation of aluminum-plastic co-extruded profiles, strictly control the quality of products, and is committed to providing customers with high-quality, high-strength aluminum-plastic co-extruded profiles to meet the stringent requirements of various types of construction projects on the performance of profiles.
