Thermoformed component having excellent coating adhesion, and manufacturing method therefor

Abstract

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 peakto-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.
