We excel at processing thin metal foils that are difficult to work with, minimizing wrinkles and burrs, and enhancing added value through punching and laminating processes.
Metal foils are used in battery electrodes, capacitors, electromagnetic wave shields, and heat dissipation materials, among others. Their thickness is very thin, ranging from 1 μm to several tens of μm, making them materials that are prone to burrs and wrinkles during processing. At Otis, we select and analyze cutting tools to minimize defects such as burrs and wrinkles, even for thin metal foils that are difficult to process, allowing us to perform high-speed and high-precision punching operations. Additionally, we not only provide bubble-free laminates that protect surfaces from rust and corrosion, but we also combine them with different materials such as resin films to enhance added value through punching, bonding processes, and layering and compounding, which are our areas of expertise. At Otis, we manufacture processing equipment such as presses, molds, and jigs in-house. Through customization and development of our equipment, we have a proven track record of processing materials and shapes that other companies could not handle. Please feel free to consult with us.

A detailed explanation of the types and characteristics of copper! We will also introduce points to consider when performing cutting processes and how to choose tools.
Copper is a metal that is softer and easier to machine compared to other metals, so even those who are not very experienced in metalworking are less likely to feel that it is hard to cut or difficult to work with. On the other hand, its stickiness and softness can make it feel challenging to process for many people, which is one of its characteristics. Copper can be classified into two types: pure copper and copper alloys, each of which can be further divided. The ease of cutting and the tips for processing differ depending on the type, so it is important to understand the characteristics of the copper being used as a material. This article provides a detailed explanation of the types of copper and their respective features. Additionally, it introduces points to consider when machining copper and how to choose tools.
