Barrel polishing includes deburring, rounding edges, adjusting surface roughness (improving smoothness), scale removal, and glossy finishing. It is also referred to as cutting barrel or gloss barrel. 【Rotary Barrel】 This is a common barrel polishing method that involves rotating the barrel. It allows for stable and precise polishing with minimal unevenness. 【Vibratory Barrel】 This method vibrates the entire barrel tank. Compared to rotary barrels, it tends to result in less impact marks, scratches, and bending. 【Centrifugal Barrel】 This method combines the orbital and rotational motion of the polishing tank for high-speed rotation. It provides strong polishing power, allowing for heavy cutting to precise finishing in a short time. Our company offers barrel polishing tailored to our customers' needs, using rotary barrels, vibratory barrels, centrifugal barrels, and other polishing methods. We can also perform consistent processing with buff polishing and chemical treatment. Please feel free to consult with us!

Electropolishing is a processing method that involves immersing polishing materials in an electropolishing solution and applying electricity to polish the surface. This results in a smooth and glossy finish on the metal surface. 【Features of Electropolishing】 - Improved corrosion resistance - Smoothing and glossing - Cleanability - Removal of micro burrs - Removal of welding discoloration Our company can provide a consistent response from barrel polishing and buff polishing as a pre-treatment. We can also handle passivation treatment as a post-treatment. Please feel free to consult with us! We will propose a processing method that suits your needs.

We offer black oxide treatment for materials such as stainless steel, brass, and zinc die-cast. Black oxide is an oxidized coating that adheres well, unlike plating or painting, making it resistant to peeling and cracking, which is a significant feature. In our brass black oxide treatment, we also handle agents that do not leave smudges, and we will guide you to methods tailored to your needs. Additionally, we provide consistent support for both pre- and post-polishing processes, so please feel free to entrust everything to us. 【Expected Effects of Black Oxide Treatment】 ■ Improved design aesthetics ■ Anti-reflective properties (mainly for optical components) ■ Corrosion resistance ■ Heat resistance ■ Suitable as a base for painting *For more details, please feel free to contact us.
