Infusion three-way valve

 Electroforming electrode The tool electrode used for EDM can be manufactured by the electroforming method. Tianjin Science and Technology Press, 1982 4 Xiao Jingrong et al. The section of the processing process 2 has a fixed slope and a large diameter of tens of microns and a hole depth of several millimeters. Nowadays, nickel sulfamate plating solution and rapid electroforming deposition process are generally used in China, and an appropriate amount of additive activator Infusion three-way valve is added to improve the degree of electroforming layer to 0.

The application of electroforming technology in the injection mold manufacturing of the National Nine Scientific and Technological Research Projects recently completed by the Fujian Light Industry Research Institute has produced high-quality mirror cores that meet the requirements of optical mirrors, and pressed optical plastic products. After filling the back of the copper shell with a solid material liner, it can be used as When using injection molds, sometimes in order to facilitate demolding, a silicone rubber mold can be used for transition.　　

The method of demolding depends on the material of the original mold. That is, the conductive original mold is used as the cathode, the metal used for electroforming is used as the anode, and the metal salt solution of the electroforming material is used as the electroforming liquid.1, a variety of injection molds with complex curved contours or fine dimensions, electrodes for EDM cavities, and other metal parts □ Electroforming mold cavities require complex shapes and high precision injection mold cavities, using traditional The processing method is very difficult. Plastic mold technical manual

. The height of the straight edge is small.Principle of Electroforming Electroforming uses the phenomenon of cathode deposition in the electrochemical process to perform forming processing. When the electroformed layer on the original mold reaches the required thickness, it is taken out, and the electroformed layer is separated from the original mold to obtain an electroformed part opposite to the original model. 13 new type 2 electroforming technology made up for the defects of conventional electroforming mold cavity. Commonly used metal materials for electroforming are copper, nickel, iron, and the corresponding electroforming solution has copper,
