[Prior Art] With the rapid changes of electronic products, consumers' requirements for electronic products not only consider their substantive performance, such as the processing speed of handheld computers or tablets, storage capacity, communication transmission of mobile phones, etc. The requirements for the appearance and durability of electronic products are also increasing. The refined texture and high-strength, high-ductility but light-weight housing will be a new trend in consumer electronics and products. The multi-colored plastic casing of traditional electronic products is easily broken by external impact, and the outer casing of a single-layer metal may be subject to corrosion due to environmental factors, or may not be subjected to subsequent surface treatment due to material properties. It is hoped that the problem of single-layer materials will be replaced by multiple layers of materials that are surnamed, scratch-resistant, high-strength and exquisite. However, the prior art produces a two-layer material or a consumer electronic device casing that is mechanically laminated by vacuum distillation or ion sputtering, however, such manufacturing costs are rather high.
