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.

Introducing the main features of copper, such as its excellent electrical conductivity, good thermal conductivity, and antibacterial properties!
Copper is the metal with the longest history, and its use dates back to 8000 BC. Copper has very superior properties compared to other metals. In recent years, especially, the trace metal action of copper (super antibacterial performance) has been attracting attention. This page introduces the main features of copper. Copper is the metal with the second highest electrical conductivity after silver, and it serves as the standard for the electrical conductivity of metal materials. Due to this property, it is widely used as an essential component in electronic devices. *For more details, please feel free to contact us.
Active in parts for precision machinery! Featuring "properties of copper" and "copper seen in everyday life."
Copper is used everywhere in our lives, but since the copper being used is often hidden, you may not have many opportunities to see it. This document is created to easily introduce copper, addressing questions such as "What are the characteristics of copper?" and "Where is copper actively used?" Please take a moment to read it. 【Contents】 ■ Introduction ■ What is copper? ■ Properties of copper ■ Copper in everyday life ■ Is copper related to SDGs? *For more details, please refer to the PDF document or feel free to contact us.
This device continuously measures the copper concentration in electrolytic copper sulfate plating solution and copper sulfate etching solution using the spectrophotometric method.
By recording the concentration in the solution and connecting the output signal to the control system, the copper concentration can be continuously maintained at the optimal level. Additionally, the detector is equipped with reference light, allowing for automatic correction of the LED light intensity changes, enabling accurate measurement of copper sulfate concentration.
Good extensibility, fatigue resistance, and corrosion resistance.
It is used as an electrical equipment material due to its excellent strength and spring properties. It is also widely used for decorative purposes due to its excellent corrosion resistance. For more details, please contact us.
There is a density of metal suitable for processing! Introducing the density of metals that you should know before making a processing request.
There are various types of metals, but did you know that each has a completely different density? The density of metals is a significant factor related to weight, and it is a point that you definitely want to understand when processing. By accurately understanding the density of each metal, you can also determine which materials are suitable for processing, potentially allowing for a smoother progression of your requests. In this blog, we will explain the densities of metals, including copper, and also introduce the characteristics of high-density metals.

Introducing the difference between copper and brass, the metals used in coins!
The coins we use casually every day are made from different metals. For example, the 100 yen and 50 yen coins are made of cupronickel (an alloy of copper and nickel), the 10 yen coin is made of bronze (an alloy of copper and tin), and the 5 yen coin is made of brass (an alloy of copper and zinc). This time, we will introduce the differences between "copper" and "brass" based on the metals used in these coins. Let's explore the characteristics of each metal through the coins that are very familiar to our daily lives. *For more details, you can view the related links.
