Cause cracks in the aluminum cladding

Because of its lightweight aluminum-coated, abrasion, heat got a lot of wardrobe vendor selection, but we also improper use will be some problems, here to give you a detailed introduction! 1, aluminum extrusion temperature is too high, the metal surface tensile strength decreased, cracks in the frictional force; 2, due to the friction of the metal surface by the action attached to tensile stress when tensile stress is greater than the surface of the metal attached to the anti- It will produce cracks tensile strength; 3, aluminum extrusion too fast, http: //www.maoxinlvcai.com metal surface suffered increased stress cause additional tension profiles cracks. Solution: strict control of aluminum extrusion process parameters in order to ensure a reasonable exit velocity and exit temperature.
