Electroplating layer of magnet knowledge

Magnet electroplating is a product appearance and storage time is very important to a work, its surface treatment is mainly zinc, nickel, copper, chromium, gold, black zinc, epoxy resin. Its surface plating is not the same as its color is not the same as its preservation time is not the same, each has its own advantages and disadvantages. 1) zinc: the surface looks silvery white, can do 12-48 hours of salt spray, can be used in some glue bonding, (such as AB glue) such as electroplating can be stored for two to five years, its advantage is that the price is relatively low. 2) nickel: looks like stainless steel color, left in the air surface is difficult to be oxidized, and the appearance is good, good gloss, electroplating can be over 12-


Magnet electroplating is a product appearance and storage time is very important to a work, its surface treatment is mainly zinc, nickel, copper, chromium, gold, black zinc, epoxy resin. Its surface plating is not the same as its color is not the same as its preservation time is not the same, each has its own advantages and disadvantages.

1) zinc: the surface looks silvery white, can do 12-48 hours of salt spray, can be used in some glue bonding, (such as AB glue) such as electroplating can be stored for two to five years, its advantage is that the price is relatively low.

2) nickel: looks like stainless steel color, left in the air surface is difficult to be oxidized, and the appearance is good, good gloss, electroplating can be 12 -- 72 hours salt spray test. Its disadvantage is that it can not be used with some glue, which will make the coating fall off. Accelerate oxidation, now on the market for nickel-copper-nickel this plating method to do 120-200 hours salt spray, but the cost of plating is relatively high.

3) copper: mostly in the hardware industry, neodymium iron boron industry is rarely used, its appearance is yellow.

4) chromium: chromium electroplating industry is also relatively rare, its plating cost is very high, the general company can not accept. But its ability to put rot is very strong, it is difficult to react with other substances. Mainly used in places with strong pH, domestic product prices are relatively low, so few people choose.

5) Black zinc: The surface of the product is treated into black according to customer requirements. In the electroplating process, a layer of black protective film is added through chemical treatment on the basis of galvanizing. This film can also protect the product, increase the salt spray time and prolong the oxidation time. However, its surface is easily scratched and loses its protective effect. Now the use of people to very few, mostly replaced by resin. Below we explain.

6) Gold: This industry is very popular now. Most of the yellow gold ornaments in some stalls we see on the street are gold-plated or copper. Gold plating makes the product look as beautiful as gold. It is generally used in the jewelry industry. Our products can also be gold plated for magnetic jewelry.

7) Epoxy resin: It is to add a layer of resin paint outside after nickel plating. This industry has only been in the market for nearly two years. Its development speed is very fast. Now there are many people using various electroplating products. Its biggest advantage is that it can do the color you want.

White film inspection is our last job. Here we have to pick up all the unqualified products, magnetize them according to the requirements, and then put them into storage.
