Introduction
The document discusses the advantages and features of the OTEC EPAG Flexmodular electropolishing unit, which is designed for polishing intricate details and inaccessible internal contours, particularly in jewelry made of yellow, red, and white gold.

Specifications
The EPAG Flexmodular is a modular electropolishing unit that can be expanded to include up to three process containers. It is capable of processing up to 40 workpieces per tank and includes a workpiece parameter management system. The unit is equipped with a USB port for software updates and upgrades, and a filter unit for absorbing particles. The process is completely cyanide-free.

Procedures
The electropolishing process reduces manual polishing to a minimum while enhancing surface quality. Gold carried over into the bath during the process can be recovered by filtering and depositing onto the cathode.

Norms and Recommendations
The system is perfect for gold and ensures that intricate details remain intact while providing an excellent finish to internal contours. The modular design allows for cost-effective expansion and easy management of workpiece-specific process parameters through the included software.

Conclusion
Electropolishing with the EPAG Flexmodular guarantees perfect surfaces even in the smallest gaps, making it an ideal solution for achieving high-quality finishes in complex jewelry designs.
