Processing mold and processing technology of biomimetic suede of a drop casting product
By using a 3D dynamic focusing fiber laser system for high-frequency submicron etching, the problem of forming uniform texture on the deep cavity sidewall of the drip molding mold was solved, achieving the processing of a delicate biomimetic velvet surface, enhancing the visual level and texture of the product, while reducing material waste.

AI Technical Summary
Existing drip molding manufacturing processes make it difficult to form uniform textures on the deep cavity sidewalls, resulting in products with overly smooth surfaces, low coefficients of friction, poor anti-slip performance, and a lack of the delicate feel of high-end genuine leather or suede.
A fiber laser system with 3D dynamic focusing is used to perform repeated etching of at least 30 layers. Combined with a grid precision of 10 micrometers or 20 micrometers and a texture material image that matches the grid precision, micrometer-level laser etching is performed to form a biomimetic velvety micropore array, realizing the construction of deep cavity and high-density micro-nano velvety texture.
It creates matte, velvety, suede-like, or composite decorative textures on the surface of drip-molded products, enhancing visual depth, surface texture, and decorative distinctiveness, while reducing subsequent surface treatment processes and minimizing material waste.
