Live Seminars

On-Site: The MCP Seminar service is designed to provide information for customers considering installation of a new electropolishing process or expansion of an existing electropolishing process. A two-day visit is usually suggested, with the first afternoon devoted to study of the existing process or product to develop an understanding of the equipment, the product requirements, and the process now in use. The following morning, the seminar is presented for your operators, supervisors, engineering/technical staff, and any other interested parties. The content of the seminar varies with the client’s objectives, but usually covers such topics as the following:

• Fundamental physics & chemistry of electropolishing
• Racking & fixture design & construction
• Process parameters & controls
• Electropolishing plant design
• Chemical process steps
• Troubleshooting
• Operation & maintenance
• New process development
• Statistical process control
• Specifications for electropolishing
• Other selected topics of interest to the client
