OKUTANI Ltd. Hall 8 / B38

Introducing the latest updates from OKUTANI in 2024, where innovation meets refinement.

With over 129 years of pioneering history, OKUTANI has consistently risen to challenges, striving to surpass customer expectations.

Building upon the solid progress we have made. OKUTANI is excited to unveil updates to our product ability. All seven main products we are sharing with our visitors this year. Including: SUPER PUNCHING, ULTRA SUPER PUNCHING, X-OPEN AREA Punching, Perforated CFRTP, Expanded CFRTP, ODS Punching and Laser Strainer.

SUPER PUNCHING/ ULTRA SUPER PUNCHING

Introducing our revolutionary SUPER PUNCHING/ ULTRA SUPER PUNCHING Technology—a breakthrough in perforation that allows for holes smaller than the metal plate thickness and hole centers thinner than the plate thickness, overcoming what was previously considered impossible in punching.ULTRA SUPER PUNCHING will further improve the utilization rate and productivity of “filtration” filters.

This development offers significant benefits across various industries, particularly in applications requiring high pressure resistance, durability, and reduced weight. Such as nuclear energy, petrochemicals, and water treatment, where effective filtration is critical. The increased plate thickness, combined with precise pore diameters, enhances material strength and longevity, reducing the need for frequent replacements.

But the advantages don’t stop there. This technology is also perfectly suited for filtration systems and vibrating sieve machines, including granulators, granule size selectors, mills, and trommel screens, all of which require high abrasion resistance.

Elevate your operations with the unmatched precision and strength of our Super-Punching Technology..Experience the benefits of our reasonably priced products by visiting our booth at Filtech 2024, and discover how this expertly crafted Japanese technology can transform your most demanding applications.

X-OPEN AREA Punching

Using Super Punching technology to achieve an "80-90%" large opening area which was previously thought impossible. With the definition as followings:

1. Round holes have an open area of 70% or more
2. Square and hexagonal holes have an open area of 80% or more
3. The bone/gap is about half the thickness of the plate (bone/gap is at least 0.5mm)

The technique of high open area perforating enabled the size of bone/gap to be half of the thickness of the plate. This is the realization of ultra-narrow pitch!

X-OPEN AREA Punching is suitable for secondary processing and has the advantage of keeping the surface flat. It offers superior advantages of high pressure-resistance, high durability, long-lasting, and weight reduction, compared to traditional perforating. The applications include air filters, audio speaker cover, housing (reinforcing materials), protecting cover, interior and exterior design materials, ventilating facilities and heat dissipation.

Perforated CFRTP

Okutani Ltd. co-development with Toray Plastics Precision Co.,Ltd. from Toray group.

CFRTP stands for Thermoplastic Carbon Fiber Reinforced Plastic. Unlike the traditional CFRP, which uses thermosetting resin that hardens permanently, CFRTP uses thermoplastics that soften when heated and solidify when cooled.

CFRTP is gaining interest because it has better physical properties. It’s lighter, stronger, and more practical for use in aircraft and high-speed trains compared to traditional CFRP. The reason why CFRTP is expected is for automotive lightweight due to enhanced fuel regulations.

Traditionally, the use of CFRTP has been limited to racing cars and ultra-luxury cars, but with mass production and lower costs, there is a growing expectation that it will be used in mass production vehicles.

Expanded CFRTP

Introducing Expanded CFRTP—a cutting-edge composite material designed for a wide range of applications. Ideal for air filters, housing reinforcements, protective covers, and speaker covers, this material offers lightweighting, formability with existing equipment, and high vibration damping.

With superior sliding properties, high thermal conductivity, and heat resistance, Expanded CFRTP is perfect for both interior and exterior design materials. It also serves as an excellent metal substitute, providing rust prevention, shortened processing times, and recyclability. Whether you need high acoustics or antistatic properties, Expanded CFRTP delivers exceptional performance across diverse applications.

ODS Strainer–Okutani Duplex Stainless Steel Sanitary Strainer

Two combined advantages make the ODS Strainer a brilliant invention. The materials and the technology!

ODS Strainer using Duplex Stainless Steel (SUS821L1 (NSSC2120®), SUS329J1 equivalent (NSSC®2351)) instead of conventional stainless steel (SUS304, SUS316L) as material, which are approximately twice as strong and wear resistant as conventional products. In addition to approximately twice the strength and abrasion resistance of conventional products, it has improved performance such as pitting corrosion resistance, and its price is stable due to its low content of rare metals.

ODS Strainer adopted Okutani’s advanced Super Punching technology and laser drilling technology from our reliable suppliers to enable a wide range of hole diameters from 0.035mm to 1.00mm. Enhancing the products reach the standard of customers– High-precision filtration, not to mention the advantages of perforated and laser opening, solves the maintenance issues of traditional wire mesh strainer.

We will introduce 2 new products at FILTECH

OKUTANI already has broken the mold and made the impossible possible.

OKUTANI was established in 1895 and has been supplying Wire Mesh and Perforated Metal over 125 years. Our history is a history of challenges, we have always tried and will continue to try new things to meet the demands of our customers.

We are going to introduce 2 new products at FILTECH 2023 in addition to Xtreme High Open Area and Super Punching introduced in 2022.

The first product is ULTRA SUPER PUNCHING.

It realizes material thickness twice the hole diameter by punching press. Our new technology allows us to perforate 3 mm holes in 6 mm stainless steel sheet.

6mm’s Tensile Strength increased approx. 2.2~2.7 times and Flexural Strength increased approx. 4.6 times compared with 3mm stainless steel sheet. Also, the production costs of punching press are significantly lower compared to drill and laser.

The second is “Sanitary Strainer using perforated Duplex stainless steel”

By replacing wire mesh with perforated duplex stainless steel, we can achieve,

• Longer service life by greatly improving durability and pressure resistance.

• High strength, High corrosion resistance, Thermal low-expansion, Polishability and Saving compared with general stainless steel.

• Easy foreign substance detection and removal by magnets.

Okutani’s advanced perforating technology enables a wide range of hole diameters from 0.035mm to 1.00mm. Available in two thickness of 0.5mm and 0.8mm.
