If you apply nickel plating to the material you want to solder, it will allow for easy soldering using standard soldering equipment, as it will be nickel soldering. This nickel plating must be heat-resistant and should allow silver solder to flow easily. Regular shiny nickel plating can become hard and crack under temperatures as high as 1000°C due to the effects of the shiny material during soldering. Of course, even with metals that are difficult to plate or bond, such as titanium, superelastic materials, and stainless steel, proper pre-treatment for each material can result in good adhesion of the plating.

We differentiate our products from others by applying various colors to SUS304 stainless steel screws using baked paint. Previously, the products were only available in stainless steel silver, but now they have become so colorful. The products in the photo feature various painting techniques such as metallic paint, glitter paint, and white pearl paint. At Wakayama Co., Ltd., we mix our own colors, so we can accommodate our customers' various color requests.

Baked paint is a hard and durable coating that is ideal for metal products, as it is cured at temperatures between 160°C and 180°C.

• Processing Contract

We respond to customer needs with ISO-quality surface treatment for materials that are difficult to coat or paint, such as titanium, NT, aluminum, and stainless steel. Please consult us if you have any concerns. For more details, please contact us or refer to our catalog.

Our company is capable of precious metal plating on materials such as titanium and superelastic alloys, which are difficult to plate, as well as stainless steel, aluminum, brass, and copper alloys. Plating is the most effective method to utilize precious metals, which are originally scarce, while keeping costs down, and it also contributes to resource conservation efforts. Of course, since it involves precious metals, it is also effective as a countermeasure against nickel allergies. We are a company specializing in surface treatment, from various types of plating to painting. For more details, please contact us or refer to our catalog.

Black nickel plating is used for decorative plating on items such as glasses and for anti-reflective (anti-glare) coatings on optical components, as well as for base plating under finishes like antique colors. It achieves a uniform blackness even on complex shapes and is cost-effective, making it suitable for various products such as decorative items and writing instruments. While black dyeing can only be applied to materials like iron and stainless steel, black nickel plating can be applied to any material that can be plated, including not only iron and stainless steel but also copper alloys, titanium, and aluminum, without material restrictions. For more details, please contact us or refer to our catalog.

Chrome plating has a beautiful appearance, is resistant to discoloration, and can significantly improve the wear resistance and corrosion resistance of the material. Our company uses plating automatic machines designed for plating treatment of stainless steel and nickel alloys, which are difficult to plate. The process includes cleaning, acid electrolysis, nickel strike, and nickel plating, followed by chrome plating, gold plating, and black nickel plating, all processed with fully automatic and semi-automatic plating equipment, allowing us to provide stable quality at low cost to our customers. Of course, plating is possible on austenitic stainless steels represented by SUS304 and SUS316, as well as ferritic stainless steels like SUS430. Please consult us regarding material specifications. For more details, please contact us or refer to our catalog. For any surface treatment needs, from precious metal plating to industrial plating, powder coating, and electrodeposition coating, feel free to consult us.

Baking paint is a painting method that hardens the paint by applying heat. Since the process from pre-drying to final baking takes about one hour, it allows for flexibility in delivery times. Two-component polyurethane resin paint, which dries at room temperature, takes more than 5-6 hours to touch dry and 4-5 days to fully cure. Baking paint offers excellent corrosion resistance even at thicknesses of about 10-30 microns. Our skilled workers ensure that the paint is applied evenly with a spray gun to achieve uniform film thickness. Our company has obtained ISO 9001 (Quality) and ISO 14001 (Environment) certifications, allowing us to perform a consistent production process in-house, from various plating treatments, zinc phosphate and chromate treatments, to electrophoretic painting, baking paint, and resin painting. This enables comprehensive quality control and centralized management of delivery times. You can trust us with any surface treatment needs.
