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,…

Recently, the key themes in the home appliance, mobile, and semiconductor industries are undoubtedly miniaturization and high integration. In precision machining sites that handle ultra-thin materials under 0.1mm, there is a factor just as vital as the machine’s performance: Stamping Oil. This “invisible player” controls the friction between the mold and the material. Today, we…

As manufacturing precision continues to reach new heights, Stamping/Punching Oil has evolved beyond a simple consumable. It is now a strategic element that determines both Product Quality and Process Cost. While oil selection in the past was limited to reducing die friction, in today’s era of ultra-precision machining, it must be viewed as a process…

Technical Spotlight: Precision Stamping Oil for Ultra-Thin Components From smartphones and wearables to semiconductors for electric vehicles (EVs), electronic components are becoming smaller and thinner every day. Today’s manufacturing floors require extreme precision, capable of punching ultra-thin plates (under 0.1mm) at speeds of thousands of strokes per minute. In these ultra-precision processes, the “invisible hero”…
