Are you facing such processing challenges in the thermal design of data centers and AI servers? "I want to arrange the fins finely to secure the heat dissipation area, but the fins tend to bend or warp due to the load from the cutting tools." "There are often burrs left inside the water cooling channels, and I feel limited in manually removing them without obstructing the flow of liquid." "I want to conduct performance evaluations before mass production, but I don't have the budget or time to create molds, so I'm looking for an accurate prototype route using cutting first." Nishimura Co., Ltd.'s microfabrication technology will bring your ideas to life. Please start with a single prototype to see if "this fine structure can be machined." *For more details, please download the PDF or feel free to contact us.
