The concept of non-digital design mold was proposed with its application and prospect in industrial design discussed. Taking the leather embossing die as the example, the process and production elements of non-digital design mold were described with the characteristics and advantages in its design analyzed as the specific performance of diverse coverage and design approaches, which could reproduce complex shapes and subtle texture in molding design, improve the efficiency of visual communication design effects and reduce costs in production design. The application of non-digital design in plane mold design, ceramic plastic mold design and rapid prototyping was prospected as well.
