三研工業 List of Products and Services

We would like to introduce our "Passivation Treatment (Pickling)" that we perform. This treatment is effective for cleaning the burn marks on the surface of stainless steel caused by welding or laser processing. When performing pickling treatment, if there is oil or other substances that have burned onto the surface during welding, it is necessary to scrub them off beforehand, so caution is required. As for the manufacturing range, the maximum dimensions for equipment are 2,500 (W) × 2,000 (L) × 2,000 (H), and the maximum weight is 2,000 kg per unit. Please feel free to consult with us first. 【Features】 ■ Confident in production capacity ■ Long items are also possible (supports equipment up to max W 2,500 × L 2,000 × H 2,000 mm) ■ Coloring and other surface treatments are also possible *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our "Nickel Plating (Electroless)" service. It is possible to increase the hardness up to Hv500±50 (with a plating thickness of approximately 25μm). Additionally, it can be hardened up to Hv1000 through heat treatment. As for the manufacturing range, for shafts, the maximum dimensions are φ350×800mm, and for equipment, the maximum dimensions are 350 (W) × 600 (L) × 800 (H), with a maximum weight of 40kg per item. Please feel free to consult us first. 【Features】 ■ We are confident in our production capacity ■ Long items are also possible (up to max φ350×800mm) ■ Coloring and other surface treatments are also available *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our "Zinc Plating (Barrel Treatment)." By passing an electric current through an aqueous solution of metal salt (zinc), zinc is chemically reduced and deposited on the surface of the workpiece. After that, a chromate treatment is applied. The manufacturing range allows for dimensions from a minimum diameter of 3.5 mm to a maximum of 200 mm, and our production capacity complies with REACH regulations. Please feel free to consult us first. 【Features】 ■ Confident in our production capacity ■ Pins, bolts, nuts, and pressed parts are also possible (minimum diameter of 3.5 mm, length up to 200 mm) ■ Coloring and other surface treatments are also available *For more details, please refer to the related links or feel free to contact us.

Our company provides surface treatment processing using "hard chrome plating." A hardness of approximately 1000 Hv can be achieved, imparting mechanical properties such as lubricity, plating thickness, mold release properties, and wear resistance at a relatively low cost, making it a highly regarded surface treatment method. We directly apply chrome plating of approximately 1μm to 30μm on the surfaces of important components such as various cylinders, rollers, shafts, and other industrial machine products as requested by our customers. Please feel free to consult us if you have any requests. 【Our Features】 ■ We are confident in our production capacity ■ We also handle long items ■ We can take care of other surface treatments as well *For more details, please download the PDF or feel free to contact us.
