Moldmakers Embrace EDM and Grinding Technologies

Conversations with moldmakers and manufacturers reveal a growing interest in electrical discharge machining (EDM) and grinding technologies. Many believe that the growing demand in medical devices, electronics, semiconductors, electric vehicles and aerospace/defense is pushing the need for advanced machining methods. These industries need extremely precise and technically advanced work and EDM and grinding are especially good at handling challenges that traditional milling and turning can’t. These technologies are becoming crucial for mold builders who want to stay competitive in an ever-changing market.

Today’s manufacturing often involves tough materials like high-performance alloys, titanium and ceramics, which are hard to machine using traditional methods like milling and turning. These materials need special cutting techniques, advanced tools and careful control of the cutting process. That's where EDM and grinding come in — they can shape these materials without cutting them directly, providing the high precision and smooth surfaces required.

For example, medical devices and components that need to be finely detailed, tiny electronic parts, electric vehicle components requiring exact measurements and aerospace parts that must withstand extreme conditions all rely on these advanced methods. These examples show why manufacturers, including mold builders, are turning to more advanced machining technologies.

What makes EDM and grinding even more attractive today is the technology behind them. Machines are not only more accurate but also use less energy and produce less waste, helping companies meet green manufacturing goals. Some shops have seen major improvements in efficiency, like using fewer electrodes and reducing the need for extra processing.

But here's where I want to hear from you: Are you seeing these trends in your shops? Have EDM and grinding transformed your approach to moldmaking? Are there nuances or insights I might have missed?
