TECHNICAL FIELD
[0001] The utility model relates to electroforming machine technical field especially relates to a kind of electroforming machines. BACKGROUND
[0002] Electroforming is a method of depositing metal on a mandrel to form a product using electrolysis. An electroforming machine is mainly composed of a power supply, an electrolytic cell, an anode and a cathode. During the electrolysis process, the metal to be electroformed is made into an anode (for example, if copper products are to be electroformed, the anode is usually a copper plate), and the mandrel to be plated is used as the cathode. When the direct current power supply is turned on, in the electrolyte (such as copper sulfate solution for electroforming copper), the metal atoms of the anode lose electrons and become metal ions that enter the solution. These metal ions move towards the cathode (mandrel) under the action of the electric field and are reduced to metal atoms on the surface of the cathode, depositing on the surface of the mandrel. Over time, the metal layer thickens, eventually reaching the desired thickness, forming an electroformed product.
[0003] The existing electroforming machine usually has uneven current distribution during the electroforming process, which makes it difficult to obtain uniform thickness of the electroformed layer. At the same time, the concentration of metal ions in the electrolyte near the cathode surface usually decreases rapidly during the electroforming process, while the metal ions in the electrolyte far from the cathode usually do not have enough time to diffuse to replenish, which can cause concentration polarization, resulting in insufficient supply of metal ions near the cathode.
