Shoe last design is a highly technical task of data plus modeling. It must combine data that conforms to the rules of the foot shape with the irregular appearance of the shoe last. This is related to whether the safety shoes fit comfortably and whether the appearance is beautiful and decent. .
In order for employers and workers to like the shoes designed and manufactured by safety shoe companies, they must master the technical knowledge of foot shape patterns and last design, such as the understanding and mastery of the following technical knowledge:
1. The relationship between foot length and last length;
2. The relationship between foot circumference, last circumference and safety shoes;
3. The relationship between foot width, last width and safety shoe width;
4. The relationship between the bottom shape of the foot shape, the bottom shape of the shoe last and the shape of the inner bottom of the safety shoes;
5. The relationship between the outer width of the toe and the outer width of the last toe and the outer width of the toe of safety shoes;
6. The relationship between the heel curvature and the tolerance convexity of the last and the back body curvature of safety shoes;
7. The relationship between the landing part of the forefoot, the landing part of the shoe last and the landing part of the sole;
These data are key technologies for the design and manufacturing of safety shoes, and are shoemaking technical knowledge that shoemaking enterprise managers and R&D designers must master.
The current design and manufacturing of labor protection shoes, whether it is intelligent production or injection molding integrated manufacturing, is inseparable from standardized assembly and molding processes such as shoe lasts, uppers, midsoles, outsoles, and insoles. The higher the degree of standardization, the lower the quality of the product. The better.
Therefore, it is necessary to require relevant responsible persons and R&D designers to master and apply these knowledge, technologies and methods, so that their enterprises can move toward high-quality, high-performance manufacturing and embark on the quality route of “high standards, refinement, and zero defects” , Only in this way can we truly become stronger and better and achieve first-line status in the field of safety shoes.
