Super group aluminum plastic composite doors and windows to explain stretch bending product parameters

Super group aluminum plastic composite doors and windows to explain the stretch bending product parameters:

1, stretch bending radius

Minimum stretch bending radius: aluminum profile (R outside -R) /R outside is less than 8%


Stainless steel profiles (R outside -R) /R outside is less than 30%


Maximum bending radius is not limited.


2. Tolerance of arc radius.


The radius is less than 1 meters, and the deviation is less than + 1mm.


The radius is greater than 1 meters, and the deviation is less than + 2mm.


3. Material calculation: the head end reserved chuck 300mm. Simple symmetrical small section section needs no test material, complicated section or big break.


The surface material needs to provide 1-2 test materials, and the material utilization rate is 95% according to the 6 meter profile.

Bending quality is good.


After spraying, electrophoresis, electroplating, polishing, drawing and other materials can be directly bent, will not damage the material surface.


The profile of cavity and complex section can be formed at one time. When the relative bending radius is allowed, the inner wall will not wrinkle and the section will not be distorted.


Stretch bending can effectively eliminate the residual stress inside the material, and the product has good dimensional stability.


Because of the cold hardening of metal materials, the material can improve the comprehensive mechanical properties of materials after drawing.
