When it comes to producing high-quality custom medals, challenge coins, pins, and badges, the polishing process plays a vital role in determining the final appearance and texture of each piece. A well-polished metal product reflects professionalism, attention to detail, and superior craftsmanship.
In this article, we’ll guide you through the metal polishing process, explore its types, and explain why polishing is crucial to creating standout custom products.
What Is Polishing?
Polishing is a mechanical finishing process that smooths the surface of a metal object by removing imperfections, scratches, or oxidation. It prepares the item for plating or painting and enhances the surface by making it brighter, shinier, or more refined.
Step-by-Step Polishing Process
1. Initial Surface Preparation
Before polishing begins, products undergo cleaning to remove oil, dirt, and debris from casting or die-striking. This ensures a clean surface for polishing to begin effectively.
2. Rough Polishing (Pre-Polishing)
Using coarse polishing wheels or abrasive belts, surface imperfections like burrs, tool marks, or uneven textures are smoothed out. This step gives the item a basic evenness and shape.
3. Fine Polishing
Finer polishing compounds and softer wheels are used to further smooth the surface. This step brings out a semi-glossy finish and prepares the item for final treatment or plating.
4. Mirror Polishing (Optional)
For high-end custom products, mirror polishing is performed to create a high-reflective, glass-like surface. This is commonly used on premium medals or VIP coins.
5. Cleaning and Drying
After polishing, items are cleaned to remove any leftover compound or dust, then dried completely to avoid stains or oxidation.
