Multi layer punching knife for shoe materials, preferred cutting tools for thick material processing

Multi layer leather punching is a common problem in shoe material processing. Ordinary punching knives are prone to material blockage and breakage, uneven upper and lower hole diameters, and brushed edges, greatly reducing production efficiency. This multi-layer punching knife is designed to address industry pain points and is a specialized tool for mainstream equipment such as Xihexi, Shanggong Fuyi, and Shibang.

Standardization of tool specifications, with a rod diameter of Φ 3.0, a conventional total length of 34mm, a cutting section standard of 12mm, and a hole diameter covering the full range of Φ 0.8- Φ 6.0. It also supports various non-standard customization and is suitable for punching needs of various shoe materials.

The core adopts a side discharge structure, which can stably process 12mm thick laminated leather. The waste material is discharged from the side without jamming the knife, avoiding material blockage and knife breakage loss from the root. The blade is precision polished, sharp and wear-resistant. After stamping, the upper and lower hole diameters are almost the same, and the holes are smooth without burrs or wire drawing, eliminating the need for secondary trimming processes.

The cutting tool is compatible with various types of shoe materials such as genuine leather and synthetic leather. Most shoe material cutting equipment on the market can be used without modification, with strong stability in mass production, effectively reducing the frequency of tool changes and lowering consumable costs. Balancing standard spot goods and personalized customization, suitable for mass production by shoe factories of all sizes, it is a cost-effective matching tool for multi-layer thick material punching processes.
