Bending S curve Aluminium profile need to set 2 parameters for both ends, each end bend 1 time, usually separate the curve line end. or separate from half of the profile as per it’s curve and length.

Aluminum profile bending need time and experience,aluminium profile need to insert bending dies usually nylon fillings or sands to fill into the hollow space. and parameter takes times to set, it is better to use un needed profile or other material to try the bending first. then use the final product before all parameters are settled correctly. always try other materials first then use final profile to avoid waste of goods.
