We use various finishing techniques at Shengen in the fabrication process. The brushed metal is one of the most popular finishes. This technique enhances metal parts’

Hard coat anodizing, or Type III anodizing, produces a thick oxide layer on the surface of metal parts. This process uses an electrolytic solution, typically sulfuric acid, to create the oxide layer. The thickness of the oxide layer created during hard coat anodizing is usually between 25 to 250 microns, depending on the specific requirements.

Anodizing aluminum is an excellent way to add durability and aesthetic appeal to your products. However, achieving the right anodized color can be tricky. If

Zinc plating, also called zinc electroplating or galvanizing, is the process of adding a thin zinc layer to a metal surface. The primary purpose is to protect the metal underneath from rust and corrosion. Zinc serves as a sacrificial anode, meaning it will corrode before the metal underneath does.

Bead blast finish is a surface preparation process that improves the surface of metal parts by spraying fine glass or steel beads at high pressure. It removes rust, paint, or other contaminants while giving the part a semi-polished or satin finish.

Bead blasting is widely used for finishing metal parts to improve their appearance, increase corrosion resistance, and prepare surfaces for additional coatings.

To polish titanium and achieve a mirror finish, you need to clean the metal, remove scratches, and use the right polishing compounds. Start with rough sandpaper, then switch to finer grits. Finish with a good metal polish and a soft cloth. Take your time at each step. The proper technique helps you get a smooth, shiny surface.

Brass finishes come in a variety of types. Popular ones include polished, satin, antique, brushed, lacquered, and oil-rubbed. Each has a different look, feel, and level of durability. Some are better for decorative use, while others resist tarnishing and hold up in industrial settings.

Stainless steel passivation is a chemical treatment designed to remove free iron and other contaminants from the surface. This process restores the steel’s natural oxide layer, which enhances its corrosion resistance.

Typically, the treatment involves immersing the steel in an acid solution, such as nitric or citric acid, followed by rinsing and drying to ensure a clean and durable surface.

Electropolishing is an electrochemical process that removes material from the surface of a metallic workpiece, typically stainless steel or similar alloys.

This technique enhances surface finish and corrosion resistance by selectively dissolving high points in the metal surface, resulting in a smoother, more reflective finish.

Stainless steel finishes refer to the various surface treatments applied to stainless steel to enhance its appearance and performance. These finishes can range from dull to highly reflective and are crucial in determining the material’s suitability for different applications.

Reflective paint for metal is a special coating that reflects light. It contains small reflective beads—often made of glass or similar materials. These beads catch and bounce light back toward their source.

This paint is usually applied in thin layers over a primed metal surface. When light hits the painted surface, the embedded beads scatter the light and reflect it. The effect is especially strong at night or in dim areas.

PVD stands for Physical Vapor Deposition. It is a vacuum-based coating process. A solid metal turns into vapor. Then, this vapor settles on the surface of the part and forms a thin, strong layer. This layer protects the surface from wear, heat, and corrosion. PVD does not involve liquid chemicals. It relies on high heat and vacuum technology.

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 small, rough edges left on a metal part after cutting, drilling, milling, or stamping. These leftover edges are called burrs. Burrs are sharp, unwanted, and often invisible at first glance. They can affect how a part fits, moves, or looks. Removing them makes the part safer to handle, easier to assemble, and better in performance.

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.
