Aluminum brittle is suspected that some profile companies all the factors of normal operation, whether the profile brittle from the cross-section is still a window assembly plant recognition level above more or less harm to the profile company's market share and customer commitment.        

        The brittle foundation of profiles is enriched in the physics of finished products and mechanical function of aluminum laser marking machine. Its basic characteristics are: opening collapse mouth, cold distortion. There are many reasons for the poor physical and mechanical functions of the finished products. Aluminum profile manufacturers mainly acquiesce in the following categories:        

        One, secret recipe and wrong material technical unreasonable        

        1, filling material is too much        

        2, impact resistance modified material plus type, total        

        3, will not change the agent too much or too little        

        4. Excessive use of external lubricating fluid        

        5, hot mixing feeding order, temperature set value and mature time on the function of profile is also a selective factor     

        Two, extrusion technology is unreasonable        

        1, raw material melting too much or lack of       

        2. Lack of engine working pressure
