Mail applications of carbide EDM blocks:<\/strong><\/h5>\n

Processing of High-Hardness and Difficult-to-Machine Materials:<\/strong> This is the core advantage of cemented carbide EDM blocks. They enable efficient machining of hard-to-process materials such as cemented carbide (tungsten carbide), titanium alloys, and high-temperature alloys using conventional methods. They are particularly suitable for manufacturing high-hardness, high-precision molds and parts, including injection molds, stamping dies, engine turbines, and medical devices.<\/p>\n

Core Conductive Component of EDM Machines:<\/strong> In wire-cut EDM machines, it serves as a critical conductive block responsible for stably transmitting high-frequency current to the electrode wire. Thanks to its ultra-high hardness, it withstands high-speed friction from the electrode wire while preventing deflection, ensuring machining accuracy.<\/p>\n

Manufacturing of High-Precision Complex Molds:<\/strong> Used in the production of molds for precision electronic components (e.g., connectors, semiconductors), it can machine extremely narrow slots, tiny holes, and other complex geometries beyond the capability of conventional cutting tools. Our company offers over 100 standard sizes and supports custom customization to meet diverse machining requirements.<\/p>\n

Fabrication of Mold Core Components:<\/strong> Featuring a combination of ultra-high hardness and favorable toughness, it is widely used to produce punches, dies, drawing dies, as well as various wear-resistant inserts, guide bushes, guide pillars, and other key parts for stamping molds.<\/p>\n
