What is a plastic electroplating signs

What is a plastic electroplating brands plastic electroplating plate is plastic products after plating metal layer, light quality, can the characteristics of the conductive, beautiful appearance, so plastic plating technology has been widely used in electronics, nameplate, optical instruments, sanitary ware, furniture, kitchen utensils and appliances, signs, car decoration, bags accessories, ornaments, gift box packing mark, machine tool buttons and light industrial products, etc. Various kinds of plastic parts. Plating on plastic signs should first consider non-conductors are plastic, not directly the plating, in response to the plastic surface pretreatment before electroplating, remove oil and impurities on the surface of the plastic to keep it clean, deposits a layer of conductive metal film, and then use it as a cathode, the plating. Plastic plating, not only can be used instead of copper, aluminum, zinc, also can reduce the processing process, reduce the production cost. Without cyanide electroplating smooth and firm, in order to make the electric plating on the industrial production of plating solution formula are often complex. Used cyanide as complexing agent to make the plating solution. But as a result of CN - To be toxic for electroplating workers health damage is very big, at the same time, discharging CN - The sewage, waste gas and serious environmental pollution. So mainly use without cyanide electroplating, plating without cyanide plating is not including CN - The plating solution of electroplating, here are two without cyanide plating solution formula: set of formula Ⅰ concentration ( g / L) Formula Ⅱ concentration ( g / L) The basic role of zinc chloride 18 ~ 20 to 40 ~ 60 offer Zn2 + ammonium chloride in electrodeposition of 220 ~ 270, 200 ~ 240 conductive salt nitrilotriacetic acid such as 40 ~ 50 15 ~ 25 complexing agent, the coating quality sodium acetate buffer, 100 ~ 200 stable coating acidity polyethylene glycol (peg) 1 ~ 1. 5 2 ~ 3 whitening agent, improve coating the brightness of thiourea 1 ~ 2 1. 5 0 ~ 2 detergent. 2 to 0. 4 a small amount of wetting agents, enhance the bonding force pH 5. 8 ~ 6. 2. 5. 8 ~ 6. 2 / temperature 5 ℃ ~ 45 A· 5 ~ 45 cathodic current density; dm - 2 to 1. 5 ~ 2. 5 to 1. 2 plastic electroplating sign is the ABS, organic glass, PC and other plastic products after plating line production of one of the electroplating signs, mainly used for LOGO and all kinds of high-grade refined decoration accessories. Product after fully automatic assembly line plating processing, on the premise of guarantee the quality of product surface, and comprehensively improve the yield and save a lot of time and cost. What is above is plastic electroplating signs is our long-term experience accumulated some experience in the manufacturing process of production, we only provide reference, reproduced please indicate: WWW. gzlid。 cn
