Hardware Electrical Casting Can Increase The Current Density, Shorten The Electroforming Time

Hardware Electrical Casting was primarily used to copy metal artwork and printed versions, and began to be used in the manufacture of compact discs at the end of 19th century. The basic principle of Hardware Electrical Casting is to use the original mould made of the desired shape as the cathode, and the Hardware Electrical Casting material is used as the anode to put in the same metal salt solution as the anode material. In the electrolytic action, the surface of the original mold gradually deposited metal Hardware Electrical Casting layer, to reach the required thickness after removing from the solution, the Hardware Electrical Casting layer and the original mode separation, then the original mold shape corresponding to the metal copy.

Hardware Electrical Casting can be divided into three categories, that is, decorative electroplating (with nickel-chromium, gold, silver as the representative), protective Hardware Electrical Casting (with galvanized as the representative) and functional plating (with hard chromium plating as the representative). Hardware Electrical Casting is one of the functional electroplating which uses Electroplating method to manufacture the product. Hardware Electrical Casting technology belongs to modern technology, and its principle is the same as electroplating. In the casting, the yin mold is the casting, the surface activation treatment has the conductive layer, the electric current, in the electric field electrophoresis causes the gold to gradually deposit in the mold casting, achieves certain thickness to be able to remove. Then polished welding, surface treatment, that becomes a beautiful Hardware Electrical Casting jewelry.

The main purpose of Hardware Electrical Casting is to accurately reproduce micro, complex and some special shape moulds and workpieces which are difficult to be processed by other methods, for example, the production of banknotes and stamps printed version, album die, type type, toy roll mold, model mold, metal artwork copy, reflector, surface roughness of the sample, Microporous filter screen, dial, EDM electrode, high-precision diamond grinding wheel matrix and so on.

Hardware Electrical Casting products adapt to many industries: mobile phones, digital, home appliances, computers, automobiles, hardware, toys, high-end gifts and so on. Hardware Electrical Casting products generally do not fade, quite suitable for: mobile phone keypad, digital keypad, camera decoration, computer guide plate, car headlights, road reflector, DVD, audio, toys, models and so on.

Hardware Electrical Casting metal usually has 3 kinds of copper, nickel and iron, and sometimes gold, silver, platinum Nickel-cobalt, cobalt-tungsten alloy, but the most widely used nickel Hardware Electrical Casting. The thickness of Hardware Electrical Casting layer is generally 0.02~6 mm, also has a thickness of 25 mm. The size error of the electric casting and the original die is only a few microns.

The original mold material has gypsum, wax, plastic, low melting point alloy, stainless steel and aluminum. The original mold generally uses the casting, the cutting or the carving method production, for the precise small mesh hole or the complex pattern, may use the photographic plate-making technology. The original mode of non-metallic materials must be electrically conductive, and the method has coating conductive powder, electroless plating film and vacuum coating.

For the original mold of metal materials, first on the surface of the formation of oxide film or coated with graphite powder, in order to peel the Hardware Electrical Casting layer.

Hardware Electrical Casting equipment is composed of Hardware Electrical Casting trough, DC power supply (usually 12 kv, hundreds of to thousands of Ann) and the constant temperature, stirring, circulation and filtration of Hardware Electrical Casting solution. The Hardware Electrical Casting solution uses aqueous solutions containing Hardware Electrical Casting metal ions such as sulphate, amino sulfonate, fluorine borate and chlorides. The main disadvantage of Hardware Electrical Casting is the low efficiency, the average thickness of the metal layer is 0.02 ~ 0.05 mm per hour. Using high concentration Hardware Electrical Casting solution, and improving the solution temperature and stirring, can increase the current density and shorten the Hardware Electrical Casting time, which can improve the Hardware Electrical Casting efficiency. This method has been applied in the Hardware Electrical Casting of nickel.
