Internal inspection of trail running shoes using water jet cutting processing.
Water jet cutting processing
With our extensive experience and track record in water jet cutting, we accept requests for prototyping and verification cutting of difficult-to-process materials such as metals, resins, and composites.
In order to run safely and comfortably in harsh environments such as unpaved roads and mountain paths, we have implemented cutting processes aimed at verifying the internal structure of high-performance trail running shoes, which are constructed with a special structure different from that of road shoes to "protect," "grasp," and "stabilize," and are equipped with high durability, high breathability, high cushioning, and high stability. Our solution involves the internal verification of high-performance shoes that are composed of a variety of fibers, resins, and rubber materials with differing hardness levels in a three-dimensional composite. Mechanical cutting tools or heat cutting methods can cause material peeling or deformation. Additionally, due to the large hollow sections, we have achieved an optimal cutting environment by highly integrating advanced settings and optimal cutting speed settings with water jet cutting. For the setting and cutting speed settings, we construct optimal settings to prevent breakage or delamination for structures that are complexly layered with materials of significantly different hardness, ranging from flexible mesh materials to high-hardness soles. By setting the optimal cutting speed according to the characteristics of the materials, we can accurately expose the internal layered structure and adhesive conditions without disturbing them.

Detailed information

As you can see in the image, despite being a composite material with completely different textures and hardness, ranging from soft fabric and mesh to the cushioning layer and hard sole part, we were able to expose a very clear and sharp cross-section without causing melting due to friction heat or fuzzing due to blade snagging. Since the internal layered structure and the arrangement of the cushioning can be accurately verified visually, it strongly supports the acquisition of highly reliable data for product evaluation and analysis.
