[0035] Low-pressure injection molding is a specialized injection molding process that uses relatively low pressure to inject hot melt material into a mold, allowing the material to solidify quickly. Compared to traditional high-pressure injection molding, low-pressure injection molding can also achieve complex shapes and fine textures, meeting designers' aesthetic requirements. At the same time, the materials used have excellent wear and chemical resistance, making the final product both beautiful and practical.

[0036] Existing low-pressure injection molding techniques often suffer from poor heat resistance. When subjected to the impact of high-temperature molten resin, surface textures are severely lost, significantly diminishing the three-dimensional texture and affecting the appearance. Furthermore, regardless of the process used, surface stain resistance is poor, making it difficult to remove stains and grease.

[0037] In view of this, see Figures 1 to 4 The present invention proposes a surface decoration structure 100 , which includes a substrate layer 1 capable of low-pressure injection molding and a composite layer 2 arranged on the substrate layer 1 , wherein the composite layer 2 includes an outermost silicone surface layer 21 .
