Roll products (long rolls, large rolls)
We provide high-quality surface treatment technology and solve problems at our two locations in Kansai and Kanto.
TWO BASES. ONE VISION.
With two locations in Kansai and Kanto, we have one of the largest production systems in Japan
We boast one of the largest production systems in Japan with two locations in Kansai and Kanto, and we have long roll plating and polishing equipment that can handle lengths up to 10m. We meet the needs of the high-performance film industry, including electrical equipment, automobiles, building materials, pharmaceuticals, and food packaging. We can also manufacture large rolls with a maximum diameter of 1.5m, and have a track record in steel manufacturing and film rolls.
Advantages of a two- locations production system
- Strengthening production capacity : With two locations, we have a monthly production capacity of 100 long rolls.
- Logistics efficiency : We respond flexibly to customer challenges such as cost reduction and short delivery times.
- Strengthening BCP system : Ability to respond flexibly to emergencies such as disasters, and maintain a sustainable and stable supply system.
Mishima boasts high-quality surface treatment and polishing technology
Mishima is proud of its plating and polishing technologies, and can quickly respond to customer requests and achieve high quality control.In roll manufacturing, we can also provide integrated manufacturing from analysis and design to core material manufacturing, plating treatment, and finishing.
Long roll (maximum length 10m)
At Mishima Kosan, we can handle long rolls up to 10m in length.
We provide an integrated system from base processing to Cr and Ni plating and finish polishing, and also handle high-quality, rare long-length Ni plating, even in Japan.
We receive many inquiries from paper and cylinder-related manufacturers, and have an extensive track record in the high-performance film industry, including electrical appliances, automobiles, building materials, pharmaceuticals, and food packaging.
Supports long rolls up to 10m
In 2022, we will introduce roll manufacturing equipment capable of handling rolls up to 10m, exceeding the 6m generally considered "long." We are preparing a system to meet the needs for longer, more precise rolls.
In particular, we have experience processing long rolls used in the highly functional film field (electrical equipment, automobiles, building materials, pharmaceuticals, food packaging, etc.), including rolls measuring Φ600 x 10m and weighing 2t. We can also handle both Cr and Ni plating.
High-precision surface treatment and short delivery time
We specialize in plating and polishing long rolls, and deliver high-quality rolls to our customers using highly accurate surface treatment technology.
With production capacity based in two locations(Kansai and Kanto) and a BCP (Business Continuity Plan) in place, we can flexibly respond to sudden requests.

Various surface treatments for roll plating
We have Cr plating technology that we have developed over more than half a century of history, and our Ni plating technology was the first in Japan to be put into practical use.
Furthermore, we also have Mishima Kosan's original "TCN dimple spraying", a coating with an extremely long life, and we perform surface treatment on a variety of products, including not only small and medium-sized items but also large diameter and long rolls.
Surface treatment technology list
With our many years of experience and technology in industrial plating, we can propose surface treatment and processing methods that take advantage of the film properties of the product, such as its use, size, and shape. Furthermore, our original patented surface treatment technology is a unique technology with excellent corrosion resistance, abrasion resistance, and mold release properties, and will take our customers' needs to the next level.
For more information on the technology, please see the "Surface Treatment/Processing Technology Search."
If you have any problems, please contact us through our FAQs or inquiries .
Wear resistance
- Dimple crystal
- Crystal coat
- TCN Dimple thermal spray
Corrosion resistance
- Ni plating
- Electroless Ni phosphorous plating (Ni-P)
Wear resistance
- F. Hard
- Pinpoint smoother
- (super) Mirror surface, etc.
TCN dimple spraying (Mishima Kosan original)
We have put into practical use the thermal spray coating "TCN dimple thermal spraying" (Patent No. 6033991), which is an innovative idea that
has both excellent wear resistance comparable to conventional WC (tungsten carbide) thermal spraying and surface properties with
an indentation suppressing effect.
Life span when used on a certain company's line (actual results)
| Material | Lifespan |
|---|---|
| Conventional shot + Cr plating specifications | 3 months |
| Plating improvement dimple + Crystal | 6 months |
| WC Thermal spray | 9 months |
| TCN Dimple thermal spray |
4 times longer life than WC thermal spray!
