Description

Technical Field

[0001] This utility model belongs to the field of automotive decorative parts surface treatment technology, and relates to an automotive decorative part with a 3D structural texture effect. Background Technology

[0002] Currently, many car brands are developing towards new energy vehicles. However, removing the grille from new energy vehicles results in a loss of unique styling and decorative effects on the front fascia. To better achieve a front-end appearance similar to gasoline-powered vehicles while also providing nighttime illumination, a process involving injection molding, spraying, laser engraving, PVD, and spraying is employed to create a 3D decorative pattern with a grille design. Injection molds can achieve a wide range of 3D structures. However, existing laser engraving techniques suffer from significantly reduced precision on large grilles, resulting in a relatively low pass rate and difficulty in controlling positional accuracy, leading to issues such as incomplete engraving and damage to the PC / PET substrate. Two-color injection molding produces serrated surface defects and has high mold costs, while spraying cannot precisely mask the surface. Utility Model Content
