川原メッキ工業所 List of Products and Services

"Black dyeing" is a treatment that causes the surface of iron to rust and prevents further rust progression. It is suitable for items that require dimensional accuracy due to its thin coating. It is recommended for products that want to be blackened or need to maintain dimensional precision. Additionally, to prevent contact between rotating and sliding metal parts, we also offer "manganese phosphate coating (Lubrite)," which does not allow phenomena such as seizure or galling to occur. 【Features (Black dyeing)】 ■ Thin coating (suitable for items requiring dimensional accuracy) ■ Low cost ■ Rust progression accelerates when "oil content" is depleted *For more details, please refer to the PDF document or feel free to contact us.

"Nickel-chromium" is a metal that can be effectively plated on materials such as stainless steel and cast iron, and it has "chemical resistance." Nickel is a metal that is close to iron, but it is much more stable against air and moisture than iron, which is why it is used in plating for both decorative and anti-corrosive purposes. However, since the surface can slightly discolor in the air, chromium plating is applied to enhance and maintain its aesthetic appeal. [Features] - Can be effectively plated on materials such as stainless steel and cast iron - Has "chemical resistance" *For more details, please refer to the PDF document or feel free to contact us.

"Electroless nickel plating," also known as chemical plating, is a method of plating metals through chemical reduction without the use of an electric power source. It is widely used in industrial applications, primarily for imparting wear resistance and corrosion resistance. Additionally, it can be applied to most metal materials, plastics, ceramics, etc., and can uniformly plate even complex shapes without uneven film thickness. [Features] - Good plating coverage in complex shaped holes - Very easy plating on iron, aluminum, brass, stainless steel, etc. - Excellent corrosion resistance - Increases film hardness and wear resistance through heat treatment *For more details, please refer to the PDF document or feel free to contact us.

"Chemical-B" is a newly developed functional plating that has excellent wear resistance and high hardness. It possesses both low phosphorus and low boron characteristics, and has multifunctionality that exceeds conventional products, particularly excelling in wear resistance under harsh conditions. Furthermore, it has excellent heat resistance and does not form a strong oxide film, which enhances the wettability of solder. 【Features】 ■ Coating composition: Nickel 98wt% or more, Phosphorus 1-2wt%, Boron 1wt% or less ■ Wear resistance: More than three times that of electroless nickel plating, exhibiting excellent properties ■ High hardness: Remains at HV700 even when plated, and can reach around HV1000 with heat treatment ■ Impact resistance: Does not exhibit cracking or brittleness even with high hardness ■ Glossiness: Unlike electroless nickel plating, it has a bright luster *For more details, please refer to the PDF document or feel free to contact us.

"Chemical-F" is a composite plating film in which fine particles of fluororesin (PTFE) are uniformly dispersed and co-deposited within an electroless nickel coating. It has low friction properties and excels in wear resistance, corrosion resistance, thermal conductivity, and possesses conductivity, making it effective for noise reduction and static electricity prevention. The characteristics and durability of the co-deposited PTFE have been evaluated, enabling a surface treatment that is unprecedented and used in a wide range of fields. [Features] ■ Base materials: Stainless steel, aluminum, alumina, iron, and other metal processed products ■ Self-lubricating: Exhibits significant effects against galling and seizure ■ Corrosion resistance: No pinholes, with uniform coverage ■ High dimensional accuracy: Can be accurately controlled to any thickness ■ Heat resistance: 450 degrees *For more details, please refer to the PDF document or feel free to contact us.

"Hard chrome plating" is a representative industrial plating with many mechanical properties and is a relatively thick plating (defined as 5 microns or more in JIS). The plated surface has a refreshing bluish-white luster that is resistant to discoloration in air and water, providing long-lasting protection for the product surface. Furthermore, it has high hardness, is resistant to friction, and is not easily worn. 【Features】 ■ High hardness: Vickers hardness of 800 to 1000 Hv ■ Wear resistance: An important fundamental property, extremely good ■ Heat resistance: Hardness rapidly decreases when temperatures exceed 300 degrees, and wear resistance also decreases ■ Corrosion resistance: Stable against chemicals other than chlorides ■ Build-up capability: Thickness of 0.5mm to 1.0mm is possible *For more details, please refer to the PDF document or feel free to contact us.
