Experimental Study of Bipolar Pulse Electroforming on Micro Optical Aspheric Mold Manufacturing


Article Preview

Compared with unipolar and periodic reverse pulse current electroforming, bipolar pulse current in electroforming is known to result in better precision and surface finish. In this paper, bipolar pulse current electroforming is introduced. The influencing parameters, such as electrolyte parameter, additives, current density, PH value, temperature and pulse current parameters have been studied on experiments. Experiments on nickel and nickel alloys electroforming on micro optical aspheric moulds have been done. The results indicated that bipolar pulse current could improve the quality and precision, reduce internal stress in micro electroforming.
