Brass rosette washer nickel plated
This is a washer for flat head screws and round flat head screws. It is also called a serrated washer. When using flat head screws, it is necessary to perform "saguri processing" on the counterpart material, but by using a rosette washer, flat head screws can be used without processing, thus eliminating that step in the manufacturing process. It can also be used in combination with round flat head screws for decorative purposes. This is a rosette washer made from machined brass material.

This is the "special-sized flat washer" series developed with a wide range of options for outer diameter and thickness compared to conventional flat washers. It stabilizes the screw head when the hole diameter of the material being fastened is larger than the screw. By increasing the surface area of the screw head, it enhances the contact with the material. It is also referred to as a washer or flat washer. It is compliant with EU-RoHS standards.
Outer diameter and thickness can be selected! Brass custom flat washers (flat washers) / nickel plated
This is the "special-sized flat washer" series developed with a wide range of options for outer diameter and thickness, in contrast to conventional flat washers. When the hole diameter of the material being fastened is larger than that of the screw, it stabilizes the screw head.

The crystalline structure has high corrosion resistance due to the amorphous non-pit and non-pin hole coating.
The ultra-corrosion-resistant electroless nickel plating has an amorphous crystal structure and a coating that is free of pits and pinholes, providing high corrosion resistance. Our ultra-corrosion-resistant electroless nickel plating contains no heavy metal additives, resulting in an almost completely amorphous structure, which offers even higher corrosion resistance than conventional electroless nickel plating with a high phosphorus content. When applied correctly, it exhibits complete corrosion resistance to acids, alkalis, seawater, chemicals, petroleum, various hydrocarbons, and solvents. In this regard, it is far superior to pure nickel and chrome alloys. For more details, please download the catalog.
Due to the properties of fluorine (PTFE), it exhibits high functionality such as non-stickiness, release properties, and lubricity.
The non-electrolytic nickel Teflon coating "Fluorube" exhibits high functionality such as non-stick properties, release properties, and lubricity due to the characteristics of fluorine (PTFE). The particle size of the contained fluorine resin (PTFE) is less than 1μm, achieving uniform adhesion and an aesthetically pleasing finish. For more details, please download the catalog.
The W effect of hardness and uniformity! Ideal for wear-resistant parts with complex shapes.
Electroless nickel-boron plating has excellent solderability and a slow deactivation rate of the coating, so there is no decline in solderability after long-term storage. While conventional electroless nickel plating oxidizes at 350°C for 30 minutes, electroless nickel-boron plating does not oxidize even at 450°C for 30 minutes. It achieves a hardness of HV1000 (during heat treatment), which is harder than hard chrome plating. The hardness during plating deposition is about Hv750, and it can be uniformly plated on complex-shaped products that require wear resistance, making it a suitable alternative to hard chrome plating for molds and mold components. For more details, please download the catalog.

Q. What are the dimensions of the hard chrome plating tank? A. We have two tanks: one measuring 1.8m in width, 3.8m in length, and 2.4m in depth, and another measuring 1m in width, 2m in length, and 1.5m in depth. Q. What is the maximum thickness that can be applied for hard chrome plating? A. It depends on the customer's request, but typically we perform standard plating (dimensioning) and thick plating. There are also methods to finish by performing other processes (polishing). Q. Can it be applied to any material? A. Mainly to iron, cast iron, stainless steel, etc., but for more details, we will respond via email or phone. Q. Can hard chrome plating be applied partially? Is it only for new products? A. It can be applied partially. Additionally, we welcome not only new products but also overhauled items. We apply it to various shapes of molds as well. Q. Sometimes the color tone of hard chrome plating appears milky white; why does this happen? A. If the plating conditions are the cause, it may occur when there is a poor balance between temperature and current. Additionally, the shape can also lead to a milky white appearance.

Newly developed copper paste "OPC Copashield SCP" for direct printing of electroless copper plating seed layers onto film.
With the evolution of IoT, various devices and gadgets are now connected to the network in addition to computers and smartphones. In particular, fields such as wearable devices and smart home appliances are expected to expand, and printed electronics, which directly print electrical circuits onto flexible materials, are attracting attention. Okuno Pharmaceutical Industry has developed a copper paste called "OPC Copaseed SCP," which can directly print a seed layer for electroless copper plating onto film, by merging the surface treatment and screen printing technologies cultivated over many years as a technology in harmony with the environment. Currently, the subtractive method using single-sided copper-clad laminates (Flexible Copper Clad Laminates; FCCL) is the mainstream for manufacturing flexible printed circuit boards. Subtractive means subtraction in English, and it forms circuits by etching away unnecessary parts from the copper foil. Our company has developed a screen printing copper paste "OPC Copaseed SCP" and an electroless copper plating solution "OPC Copper HFS" for printed electronics. This process enables the reduction of environmental impact and improvement of productivity.
Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on the circuit surface.
Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on circuit surfaces. The "ICP-COA process" is a low film thickness Ni-P/Au plating process that utilizes a reducing cobalt catalyst. This process consists of a reducing cobalt catalyst solution "ICP Accel COA" and an electroless Ni-P plating for cobalt catalysts "ICP Nicoron COA-GM." In conventional processes using palladium, the copper material corrodes during the catalyst application step, leading to the formation of voids between the copper material and the plating film, which has been a challenge. In this process, a uniform catalyst film can be formed through reduction deposition, enabling the reduction of the film thickness of electroless nickel plating (electroless nickel plating thickness: conventional process: 3.0µm, ICP-COA process: 0.5µm). Furthermore, since a void-free and well-covered film can be obtained, it is possible to reduce the film thickness of electroless Ni plating without compromising solder joint reliability.
