How to add antimicrobial copper inlays to aluminum bin handles?

To add antimicrobial copper inlays to aluminum bin handles, follow these steps for a durable and hygienic upgrade. First, clean the aluminum handle thoroughly with a degreaser to remove dirt and oils, ensuring a smooth surface. Measure and mark the areas where the copper inlays will be placed, typically high-touch spots like grip zones. Use a precision tool, such as a router or CNC machine, to cut recesses into the aluminum handle, matching the thickness of the copper sheets—commonly 1-2 mm thick. Cut the copper pieces to fit these recesses snugly, and clean them with a mild acid solution to activate the antimicrobial properties. Apply a high-strength epoxy adhesive designed for metal bonding to both the aluminum recess and copper inlay, then press the copper into place, removing excess adhesive. Secure it with clamps and allow it to cure as per the adhesive instructions, usually 24 hours. Finally, sand the surface smoothly to blend the edges and polish the copper for a finished look. This method leverages copper's natural ability to kill microbes, reducing contamination risks on frequently handled surfaces. Regular cleaning with non-abrasive products will maintain the inlays' effectiveness over time. Always wear safety gear like gloves and goggles during the process to prevent injuries.
