Point02
Solving customer problems with optimal
structural design and coating
structural design and coating
We propose the optimal structural design according to size and usage, and manufacture high-quality products that satisfy our customers, from surface coating to finishing (mirror grinding). Please contact us.
Roll body strength
With structural analysis, design the optimum structure of the roll body according to the usage environment and load.
Roll body cooling
For rolls used in high-temperature environments, we design the optimal cooling structure through heat transfer and fluid analysis.
Surface coating
Optimal coating specifications are designed according to the purpose and operating environment by combining our original coating technology with heat transfer and structural analysis.
Point03
Surface treatment technology for
a wide variety of applications
a wide variety of applications
We have our own equipment that can handle a wide variety of surface treatments to meet the needs of our customers.

Releasability
- F. Hard
- Pinpoint smoother
- (super) Mirror surface, etc.
Long-lasting coating realized!
TCN Dimple thermal spray
(Original by Mishima Kosan)
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!
36 months

Longer high-performance film!
Addition of 10m long equipment!
(Newly established in December 2022)
High-performance films are functional films used in various fields such as electronics, automobiles, construction materials, pharmaceuticals, and food packaging. In addition to larger sizes, there is a demand for longer lengths and high-speed rotation.
