Why are vibration finishing and powder coating used separately on the sofa's metal parts?
This question is asked when someone wonders what roles the two processing methods play, as vibration finishing and powder coating are listed separately for different metal parts in the detailed description.
This is because stainless steel vibration finishing and steel powder coating were designed separately according to the parts of the sofa body[1].
Certain parts are stainless steel, and other parts are steel[2]. The blank daybed sofa by munito is constructed by differently selecting metal materials and surface finishes depending on the body parts[3].
The finishes are different. Vibration finishing is a method that creates a subtle matte look by engraving fine, irregular swirling grains on the surface with an abrasive, helping to make everyday scratches or handprints less noticeable. Meanwhile, powder coating applied to steel is a processing method in which a fine powder paint is applied and then baked at high temperatures to form a hard film. It coats the surface evenly, preventing the paint from peeling off easily and preventing rust on the steel material.
It has not yet been confirmed specifically which of the body parts use stainless steel and which use steel.
