Abstract (en)
[origin: EP4067530A1] A thermoformed component having excellent coating adhesion. The thermoformed component comprises a substrate layer and an aluminum coating coated on at least one surface of the substrate layer. The average roughness Ra of a surface of the thermoformed component is between 1.0 µm and 3.0 µm, the peak height and the peak-to-valley height Rt are between 8 µm and 30 µm, and the roughness peak count Rpc is greater than or equal to 50. A manufacturing method for the thermoformed component having excellent coating adhesion comprises the following steps: (1) immersing a substrate in an aluminum coating solution to obtain a plate having an aluminum coating on a surface thereof; (2) performing leveling; (3) performing blanking on the plate or cutting the plate to obtain a blank having a required component shape; (4) performing heat treatment; and (5) performing transfer processing and hot stamping, wherein the heated blank is quickly transferred to a mold for cooling and stamping to form a thermoformed component.
