We provide high-quality roll products that meet customer needs through
an integrated construction system.

We offer an integrated system from design to production and delivery of various roll products and parts.

In addition to conventional surface treatment technology, we respond to
the diverse needs of our customers with various original plating and thermal spraying that are excellent in corrosion resistance, wear resistance, and releasability.

Providing high-quality and highly reliableroll products through consistent manufacturing

From order receipt to delivery, we provide roll products that meet customer needs with thorough quality control and advanced technology.

Solving customer problems with optimal 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.

Surface treatment technology for
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.

Wear resistance

Corrosion resistance

  • Ni plating
  • Electroless Ni phosphorous plating (Ni-P)


  • 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
