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”…

Technical Challenges of Cleaning Ultra-Thin and Ultra-Precision Components Why Do Conventional Cleaning Methods Reach Their Limits? The electronic components industry is evolving rapidly. With the expansion of AI, high-speed communications, electric vehicles, and high-current systems, electronic terminals and connection components are becoming thinner, smaller, and more precise. Ultra-thin materials below 0.1 mm, high-speed continuous stamping,…

As smartphones, secondary batteries, and semiconductor components continue to become smaller and thinner, the challenges faced on press processing floors are also intensifying. In extreme environments where ultra-thin materials—less than 0.1 mm thick—are stamped more than 1,000 times per minute, conventional punching oils can no longer withstand the demands. In the era of technological super-gap…

Why Is “Precision Cleaning” Now Essential for Electronic Components? In the electronics industry, the stamping process is a core technology for mass production. Lead frames, connectors, terminals, springs, EMI shielding components, and most electrical contact parts are manufactured through stamping. However, one critical factor in this process is often underestimated: Cleaning. In many production sites,…

In heat treatment processes, we often hear statements like: “This steel grade needs to be quenched quickly,” or“If this is cooled too rapidly, it will crack.” However, the key factor that truly determines heat treatment quality is not simply the cooling rate itself,but the pattern of cooling—namely, the cooling curve of the quenching oil. Heat…

— Key Factors for Improving Machining Quality and Cost Efficiency — In electrical discharge machining (EDM), electrode wear is an inevitable phenomenon, but it is also a controllable variable. Excessive electrode wear leads to reduced dimensional accuracy, increased correction work, longer machining time, and higher overall costs.While many shops first review machining parameters or electrode…

Electrical Discharge Machining (EDM) is a precision process where performance is driven not only by machine settings and electrodes, but also by the quality and characteristics of the EDM oil. Many shops focus on power parameters and tooling, yet overlook how dielectric fluid selection directly impacts cutting speed, machining stability, surface quality, and overall productivity.…

Aluminum is widely used across many industries—including food packaging, automotive, electronics, and home appliances—thanks to its light weight and excellent formability.However, aluminum behaves very differently from steel during press operations, which makes general-purpose punching oils insufficient for stable and efficient production. This is why aluminum-specific punching oils are becoming increasingly important. 1. Aluminum Is a…
