There is a common misconception when handling lubricants on the mold machining shop floor: the belief that “oil must always be thick and highly viscous to protect molds effectively.” For processes using general stamping or press oils, this might be true to some extent, as a strong oil film prevents physical friction. However, in Electrical…

There is a concern that anyone working in a metalworking site, especially one using water-soluble cutting fluids, has likely experienced at least once: the pungent stench that fills the factory on Monday mornings. This odor is more than just an unpleasantness; it is a clear warning sign that the cutting fluid has ‘rotted.’ If left…

As raw material prices surge and manufacturing cost pressures intensify, ‘consumables’ are often the very first target for cost reduction in many mold and parts machining facilities. Among these, the hundreds of liters of Electrical Discharge Machining (EDM) fluid required for EDM machines present a noticeable difference in unit price, making it incredibly tempting to…

In high-speed press machining environments producing ultra-precision electronic components, secondary battery parts, and semiconductor lead frames, a constant war against “friction” is waged every second. In harsh conditions where ultra-thin materials of 0.1mm or less are processed at hundreds to thousands of strokes per minute (SPM), immense heat and pressure are generated on the die…

Cylindrical battery cans, sink bowls, automotive oil pans, and beverage cans. What do these all have in common? They are all manufactured using the Deep Drawing process, which seamlessly presses flat sheet metal into deep, three-dimensional cylindrical shapes. Deep drawing is an advanced manufacturing technique that maximizes the plasticity of metal (its ability to permanently…

The hottest topic in the manufacturing industry lately is undoubtedly “ultra-precision.” Particularly, from core components for secondary batteries and precision automotive gears to aerospace and defense parts where not even a 0.01mm margin of error is tolerated, the tolerance standards required for metal processed parts are becoming stricter day by day. To mass-produce these ultra-precision…

Today’s trend in the electronic component industry is clear: “Thinner (ultra-thin sheets), Faster (high-speed pressing), and More Precise (ultra-precision machining).” In extreme processing environments that battle thicknesses under 0.1mm and stamp thousands of times per minute, the role of stamping oil, often used without second thought, has become incomparably more important than in the past.…

What is the first step to reducing defect rates and extending die life in ultra-precision press machining? The most basic, yet frequently overlooked fact is that “every metal has its own unique physical and chemical properties.” ​ Attempting to process aluminum, copper, and stainless steel all with a single, general-purpose stamping oil inevitably leads to…

The smartphones we hold and use every day are not simply an assembly of cutting-edge software. Looking inside, they represent the “essence of precision manufacturing,” where microscopic metal components operate tightly interlocked, allowing not even a 0.1mm margin of error. In the process of stamping out such small and intricate parts with high-speed presses thousands…

Along with the rapid growth of the electric vehicle (EV) and energy storage system (ESS) markets, secondary battery manufacturing processes are becoming more sophisticated by the day. Just as important as the chemical technologies that increase battery capacity and charging speeds is the “precision machining technology” that guarantees yield and safety. ​ Among these processes,…
