Business content

"Quality," "delivery time," and "price" are a given. Kodan Metal Co., Ltd. is confident that adding a "playful spirit" to these three will result in even better sintered body processing. "Good work" and "playfulness" may seem contradictory at first glance, but we believe that it is worthwhile to deliberately include them in order to do work one step further. For Kodan Metal, "fun" is the highest compliment.

Product and Technology Introduction

Only a ball-binding craftsman can create this

Metal filters best suited to your application

● Optimal sintered body processing based on 30 years of experience
● Simultaneous sintering eliminates the need for welding between sintered parts and metal parts.
● Stackable "laminated wire mesh plate"
● Machining of sintered metal by clogging removal process
● Fabrication of porous materials by coarse particle bonding
 
As a master of sintering, we leverage the functional properties of porous metal bodies to propose optimal components for solving problems such as impurity filtration in fluids, sound energy absorption, various gas venting, explosion prevention, and fluid rectification.

Sintered metal (porous)

Achieving "high strength" with "low density"

Porous sintering of small metals

At Kodan Metal, we manufacture porous sintered bodies by using metal particles to increase the size of the voids (spaces) within the element. By adjusting the size of the metal powder (particles), we can manufacture products according to the intended purpose.
The materials used are diverse, including bronze, stainless steel (SUS), pure aluminum (Al), pure copper (Cu), pure titanium (Ti), and alumina (Al2O3).
We handle everything from prototypes and research and development starting from a single unit to mass production of thousands of units. Furthermore, we can process and weld metal fittings to match the sintered body.

Simultaneous sintering

At Kodan Metal, we use our unique simultaneous sintering process for joining sintered and metal parts. Because there is no welding interference, it can be applied to precision sensors. Furthermore, we can also perform plating using our proprietary technology upon request.

Laminated wire mesh suction plate head

It can attract materials that are not normally attracted to magnets.

Wire mesh is connected at points

Laminated wire mesh is made by layering stainless steel wire mesh, sintering it, and joining the pieces together at point contact.
In small metal mesh filters, the number of overlapping wire mesh layers is used to adjust the filtration pore size.
It has no peeling or splitting, excellent workability and durability, can be used repeatedly without problems for long-term use.
Furthermore, it can handle up to 7 layers of laminated material, enables mold-free processing, and can accommodate prototypes and research and development starting from just one unit.

Laminated wire mesh

Ideal for suction plates

The wires are woven together, and no matter which cross-section you observe, the contact surface is spherical. Therefore, it does not cause the kind of snagging that occurs with sintered metal suction plates.

Furthermore, a "fluorine coating" surface treatment is also possible, which allows it to "repellent" water while "permeating" air.

Opening up the world with unique and innovative sintered metals.

Job Description: Japan's leading processing capability, handling sintering of 15 different materials.

The company built its foundation by manufacturing and selling its original product, "miniature valves," utilizing its cutting technology. Following the oil crisis, it expanded its business by inventing mounting systems for solar water heaters. This technology has since been applied to mounting systems for solar cells, contributing to the government's push for renewable energy. The development of sintered metals began in 1980, when the company was commissioned to manufacture exhaust silencers for compressors, using sintered metals for filters. Initially limited to products using bronze and shavings of stainless steel, the company successively introduced sintering machines for new material development to strengthen its research and development capabilities. Currently, it boasts overwhelming processing capabilities in Japan, capable of sintering 15 different materials, including metals such as titanium, copper, nickel, and aluminum, as well as non-metals like ceramics and glass.

Strengths: Sintered metal filters used in cutting-edge fields

Our basic policy is to "always challenge ourselves with original ideas while never forgetting to have fun."
We respond sincerely to customer inquiries, even if it involves a material we've never used before, without ever refusing to help.
The company has a wide range of advisors who provide technical support, including Ryosuke Matsumoto, Associate Professor at Kansai University's Faculty of Systems Science and Engineering (Doctor of Engineering), Kyosuke Sasaki, Visiting Professor at Gifu University (Doctor of Engineering), and Yoshio Furuta, President of Furutech Co., Ltd. (Doctor of Engineering). Sintered metal filters are used in cutting-edge fields, such as critical components for Japan's first hydrogen station, satellite and probe components delivered to the Japan Aerospace Exploration Agency (JAXA), and a fine powder recovery device jointly developed with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

Sintered metal filters: Introducing a new material development sintering machine, transforming into a research and development-oriented company.

This porous sintered metal is created by melting only the surface of spheres with precise temperature control, causing the spheres to weld and bond together. In the sintering field, dense materials dominate the market for materials above 90%, with porous sintered metal filters remaining limited to around 2%. It is an eco-friendly product with excellent heat resistance and strength, and is expected to see future applications in filtration, sound absorption, and more. Leveraging the agility of a small to medium-sized enterprise, the company aims to become a unique company by deepening its expertise in this niche field. The relocation to a new headquarters building in 2008 is positioned as the company's second founding period, and in 2013 and 2014, sintering machines were introduced for new material development, aiming to transform the company into a research and development-oriented enterprise.

Future prospects: Expanding overseas through Hannover Messe and strengthening the medical field.

"We obtained ISO 9001 certification in 2014 and plan to obtain ISO 14001 certification in 2015, aiming to become a company that prioritizes quality control and environmental management. In 2016, we plan to obtain a "Management Innovation Plan" based on the Small and Medium-Sized Enterprise New Business Activity Promotion Act. In 2019, five years from now, we plan to participate in Hannover Messe in Germany, which is said to be the world's largest industrial technology trade fair, to use as a foothold for overseas expansion. Domestically, we will strengthen our efforts in the medical field, where there is a high demand for high value-added, high-performance products and where the rust-resistant characteristics of our products can be utilized."

Our company history

Founded in 1960, the company started with machining and built its foundation with brass miniature valves. After the oil crisis, its solar water heater mounting frames and gasoline cans became hit products, expanding its business. With the start of the full purchase of renewable energy, the company applied its solar water heater technology to solar panel mounting frames, achieving success. The development of sintered metals began in 1980. Initially limited to bronze and needle-shaped stainless steel, the company successively introduced sintering machines for new material development, and now boasts the largest processing capacity in Japan, sintering 15 different materials, including titanium and ceramics.

Our strength lies in our "research and development-oriented factory," which makes the most of our in-house laboratory functions and is constantly evolving.

Main business activities

Design and fabrication of sintered metals, precision machining of various metals, fabrication of solar panel mounting frames, and our own brand of sealing tape.

Main customers (delivery destinations)

Medical device manufacturers, precision instrument manufacturers, gas detector manufacturers, medical research institutions, universities and other research institutions
