The side panels of the refrigerator shell are not merely structural components; they are also the "appearance representatives" that consumers first notice. During the forming process, surface quality control is the aspect that customers are most concerned about.
Common problems:
After forming, there is an "orange peel" effect, and the surface is not smooth;
The plates have excessive friction between passes, leaving scratches or indentations;
The coating is damaged during forming, making it prone to rusting later.
Solution:
The surface of the rollers must be coated with chrome plating or ceramic spraying to reduce friction and protect the coating;
The forming angle should gradually transition to avoid excessive bending at once;
The equipment can be equipped with a coating protection film device to protect the plate surface throughout the forming process.
These details directly determine whether the refrigerator in the store has "high-end texture" or is "cheap at first glance".
