If you work with sheet metal fabrication prototype models—whether for automotive, elektronik, or consumer goods—you know that surface treatment is key to boosting durability and appearance. Anodizing is one of the most reliable methods, as it creates a protective oxide film that enhances corrosion resistance and wear resistance. But how do you do it correctly? […]

Polishing sheet metal fabrication prototypes is more than just making them look good—it removes burrs, smooths rough edges, and boosts durability, which is critical for testing functionality and impressing stakeholders. Whether you’re working with steel, aluminium, or copper prototypes, following the right steps and using the correct tools will save you time and avoid costly
