The GP-G model identifies machines specially designed for HIGH PRODUCTION of gold pieces in their different colors and karats, although there is also a version for silver. This model performs a fine ELECTRO-FINISHING of exteriors in longer times than the PMG system, but considerably shorter than in mechanical processes.

GP-G machines allow between 26 and 66 parts to be processed simultaneously in times ranging from one to two hours, depending on the capacity of how bulky they are.
