Prototype mold fabrication for the core and cavity of a MiFi product using a 700x350 CNC milling machine and SS400 steel

Abstract This study aims to develop a mold prototype for a MiFi product, specifically focusing on the core and cavity components, using a CNC milling machine with 700x350 mm dimensions and fabricated from SS400 alloy steel. The mold and fabrication methodology were done through CAD design, CAM programming, and a meticulous CNC machining process. The selection of SS400 material was based on its commendable mechanical strength, ease of machinability, and cost-effectiveness for prototype applications. CNC milling technology enabled the production of molds with high dimensional accuracy and smooth surface finishes, meeting the required specifications for the MiFi product. The resulting prototype provides a foundation for further development. This study significantly contributes to optimizing the mold manufacturing process and demonstrates SS400 as a viable alternative material for prototype molds.
