- Composition of electroformed sign products:
(1) Base material: nickel (thickness according to customer samples or drawings);
(2) Surface treatment: chrome plating (enhance the wear resistance and surface hardness of the product);
(3) Filling: AB glue (epoxy resin, thick stickers only);
- The process principle of electroforming
Electroforming is a process that uses the principle of electrolysis to deposit a certain thickness of metal on a mandrel or sample, and then separate the two to make a mold cavity. The precision and smoothness of the cavity of the electroforming mold are completely consistent with the core mold. Electroforming is also known as the “cloning” technology of non-living substances.
- Characteristics of electroforming:
- Can accurately and accurately copy the profile and fine lines;
- Can obtain replicas with high dimensional accuracy and surface roughness less than 0.1um. The electroformed products produced by the same original mold have good consistency;1) The shape of the electrocasting part and the master mold are highly consistent. As long as the master mold is manufactured accurately, the precision of the electrocasting part can meet the requirements, and the surface roughness Ra can reach 0.1µm. 2) Electroforming is formed by the deposition method. No matter how complex the shape is, electroforming can replicate it very well. It can also form a cavity that is difficult to form or even impossible to form by machining. Electroforming speed: (taking electroforming nickel as an example) 5-300μ / h. The strength of the electroformed (nickel) layer σb = 340-600MPa, the hardness HV100-220, and the contact surface (inner cavity) of the mandrel with the accuracy of ± 1μ, the thickness of the electroformed layer can reach 0.1-5mm.
