EP10 Chassis

The EP10 Chassis is a complete, stand-alone electropolishing system originally designed and built by SDC to electropolish small stainless steel medical implants. The EP10’s small size, advanced controls, and proven durability offer an ideal alternative to large electropolishing systems for precision medical devices.

Solid Construction

From the EP10’s stainless steel uni-body construction, to its Teflon-coated cooling coil, all exposed materials used on the EP10 are made to withstand the temperatures and the corrosive solutions used in electropolishing.

Customization & Integration

Each EP10 is built on request and SDC offers custom designed parts-handling systems, including parts feeding, fixturing, manipulating, and unloading. SDC can also offer complete custom integration for any specific application.

Machine Programming

The EP10’s user-friendly touch-screen control system can be customized to your specific application. The touch-screen display allows you to save, modify, and select electropolishing "recipes" for different parts.

About Electropolishing

Electropolishing is an increasingly common method for polishing and deburring ferrous and nonferrous metals. Electropolishing systems work by smoothing, polishing, and deburring metal surfaces in an electrolytic bath. This process selectively removes high points on the metal surface while producing a uniform, high luster.

Electropolishing works by immersing a metal part in liquid media and subjecting it to direct current. The metal part becomes anodic (+) while another metal, usually lead, copper, or stainless steel, is used as a cathode (-). The direct current flows from the anode to the cathode, removing metal ions at a controlled rate. The amount of metal removed is dependent on the specific bath, temperature, speed, and alloy being electropolished.

Unlike conventional mechanical finishing systems, this process does not smear, bend, stress, or fracture the crystalline metal surface to achieve smoothness or luster. Instead, electropolishing removes metal from the surface while producing a unidirectional pattern that is stress- and occlusion-free, microscopically smooth, and often highly reflective. In addition, improved corrosion resistance and passivity are achieved on many ferrous and some nonferrous alloys. This same process is used for micro- and macro-deburring, as this reverse plating process selectively removes metal ions from high points on the surface without etching it.

Note: Steven Douglas Corp. (SDC) is not an electropolisher or metal finisher, and does not offer electropolishing services. Features and specifications are subject to change without notice.
