Heat treatment is a process where aluminum is heated and then cooled in a specific way. The goal is to change the internal structure of the metal. This change affects the metal’s hardness, strength, and flexibility.
Manufacturing products with sheet metal poses unique challenges. Many engineers and designers struggle with precision cutting, material waste, and inconsistent quality in their production runs.
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.
Fine blanking is a specialized metal forming process that combines the principles of stamping and shearing to produce high-precision parts. It utilizes a unique setup involving a punch, counterpunch, and a blank holder, allowing for minimal clearance and controlled material flow.
Oxy fuel cutting is a method for slicing through steel using a torch. The torch mixes fuel gas and oxygen to heat the metal surface. Once the steel reaches its ignition temperature, a jet of pure oxygen is blown through the heated area. This burns the metal and forces out the molten oxide, creating a narrow, clean cut.
Sheet metal punching transforms flat metal sheets into functional components. This process uses specialized tools called punches and dies to create precise holes and forms in metal sheets. During the punching process, a punch tool moves downward with significant force to penetrate the metal sheet. The die below the sheet supports the material and allows the punch to create clean cuts.
The metal strength chart helps match material strength to the task. It shows values like tensile strength, yield strength, and hardness. These numbers help you pick a metal to handle your loads, heat, or wear. Use this chart when comparing options during product design or sourcing. It saves time and cuts mistakes.
Mild steel and stainless steel differ in key ways like corrosion resistance, strength, cost, and application. Mild steel is strong and affordable but rusts easily. Stainless steel resists corrosion and looks better, but it costs more. The best choice depends on your project’s environment, budget, and performance needs.
316 and 316L are both austenitic stainless steels with excellent corrosion resistance. The key difference? 316L has less carbon, making it better for welding and high-temperature applications. 316 offers slightly higher strength in non-welded, room-temperature uses.
The choice between Aluminum 6061 and 6063 depends on your project requirements. Aluminum 6061 is stronger and better for structural applications. It works well in parts needing toughness, corrosion resistance, and machinability. Aluminum 6063 is more suitable for decorative or architectural uses. It offers excellent finishing qualities and is easier to extrude into complex shapes.
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.
We are often asked questions at Shengen about sheet metal fabrication. A question we often get asked is, “How to weld brass?” It may be
Stainless steel is visually appealing and boasts impressive corrosion resistance, durability, and strength. These qualities make it popular in various applications, from kitchen appliances to
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).
