Black oxide finish, or blackening or oxidizing, is a chemical conversion coating primarily applied to ferrous metals. The process involves treating the metal with an alkaline solution containing oxidizing salts, which reacts with the surface to create a thin layer of black iron oxide (Fe3O4).

Deburring is the process of removing minor imperfections, known as burrs, from metal parts after machining. These burrs are typically sharp, jagged edges that can affect the functionality and aesthetics of a part. By deburring, we ensure the parts are smooth, safe to handle, and fit for their intended use.

Polishing aluminum is an art that combines the right tools, abrasives, and techniques. Start with a clean surface and work through progressively finer grits of sandpaper. Use a polishing compound and buffing wheel for the final shine. The key is patience and consistent pressure throughout the process.

Imagine this: you’ve just completed a brilliant sheet metal fabrication project that needs something added – a touch of branding or design. That’s where silk

Powder coating is a finishing process where a dry powder made of pigments and resins is electrostatically applied to a surface. The coated part is then heated, causing the powder to melt and form a smooth, durable layer. This method is particularly effective for aluminum, providing a strong, long-lasting finish that protects against wear, corrosion, and environmental damage.

In your line of work, you must have encountered many metal finishes. As the CEO of Dongguan Shengen Metal Co., Ltd., I’ve personally dealt with

Metal surface finishing alters metal surfaces through mechanical, chemical, or electrochemical processes. The process involves adding, removing, or reshaping metal surfaces to achieve specific characteristics. Common techniques include grinding, polishing, coating, and plating to improve functional properties and visual appeal.

When I speak with customers from around the world, the topic of the importance of surface finish for metal fabrication is a constant. As a
