In fact, there are wholesale shop owners and employees in wholesale stores in wholesale markets. There are also wholesale manufacturers who produce directly, as well as wholesalers who receive products from factories and assemble them using parts.
Therefore, there are many cases where people do not know exactly about the plating of products.
So, I would like to provide additional information on plating.
Plating thickness
When talking about plating thickness at Namdaemun, the term "mils" is used. If the plating is thicker, there are advantages such as delaying discoloration and making the color of the plating look prettier.
Most of the products that are plated in Namdaemun, such as earrings, necklaces, and rings, are plated at a thickness of about 1-3 mils.
If they want to make it slightly cheaper, they use 2 mils, and if they want to put more effort into plating, they use 3 mils.
However, the thickness can vary depending on the skill of the plating factory. Since the plating process is done by people, the thickness of the plating can vary depending on the person.
Sometimes, even if the plating factory says they produced it with 3 mils, it can be 1 mil or 2 mil in reality. Therefore, wholesale companies that care about quality measure the thickness of the plating factory's plating on a regular basis.
Why can thickness vary?
This is because the thickness of the plating can vary depending on the time it takes to put the product into the plating solution and remove it.
As mentioned earlier, if the plating thickness is thin, discoloration occurs easily, and if the plating thickness is thick, discoloration is delayed.
So, you might think, "Wouldn't the quality be better if we just made the plating thicker for all products?" Yes, that's correct.
However, the thicker the plating, the more expensive it becomes. Therefore, each wholesale company has to choose the thickness of the plating because the thickness of the plating increases the cost.
Therefore, one of the reasons why the price of similar designed products differs is the thickness of the plating.
If you want to pay more attention to discoloration of plating, you can request thicker plating from the wholesale company and specify a thickness like 6 or 10 mils.
Plating method
"We do electroplating."
Sometimes, you might hear this kind of story when you go around Namdaemun wholesale market.
You might think that they are using a better method for plating than others.
However, most of the plating is currently done by electroplating. So, if a company emphasizes electroplating like this, it doesn't have much meaning.
As mentioned earlier, electroplating is a method of making the product (metal) to be plated by passing (+) (-) electricity through it to make the plating adhere well.
However, even in this plating process, there are things to consider.
Among the types of plating colors, silver-colored plating is easier than gold or rose gold plating because it is less prone to discoloration. Therefore, the plating process for silver-colored plating may be easier than that for gold or rose gold plating.
However, in the case of gold plating, there is a process where the plating solution is adsorbed by flowing electricity while the product (metal) is immersed in the plating solution and then the electricity is turned off and then turned on again. (This process of turning off and on electricity is called "bouncing").
The Layers of Plating
I will explain the impact of quality using gold plating as an example.
For example, when the material is brass, instead of directly gold plating on the brass material, a process called under-plating is done, which involves applying copper plating or other materials on top of the brass material. The reason for copper plating is that if gold plating is directly applied to the brass material, the external surface of the brass may be slightly rough, making it difficult for the gold plating to be smooth. Therefore, copper plating is used to make the rough surface of the brass material smooth.
The important thing here is that if the under-plating process (copper plating or other materials) is not done well, discoloration can easily occur. The brass material itself emits gas, and if the under-plating is not done properly, the gas can easily escape, leading to rapid discoloration.
After gold plating, there is also a post-processing stage. The post-processing stage also plays a role in reducing the discoloration of the plating. So, not only is gold plating important, but the under-plating and post-processing stages also affect the quality of the plating. Therefore, multiple plating processes must be well-executed to improve the quality of the plating.
That's why it's important for wholesale companies to find a good plating factory or a skilled plating technician. Each plating process must be harmoniously carried out for the quality of the plating to improve.
Therefore, it's not about doing business with the plating factory, but with the plating technician. Some wholesale companies even change their suppliers when the plating technician moves to a different factory.
Oh, but the cost of plating increases the wholesale price of the product. A factory that pays more attention to plating will take longer to plate a single item, resulting in a higher cost. Therefore, a good plating factory = an increase in plating price.
So, if there's a wholesale company that uses nickel plating on brass and is more expensive than others, but the plating color is luxurious and lasts longer, it's natural to think that this company is paying attention to quality and making the plating thicker. Therefore, I thought that this company would use a plating thickness of more than 3 mills.
However, they use a plating thickness of 3 mills, similar to other wholesale companies. So why does this company's plating color look better and the product more luxurious? I thought that the reason why the quality was good was not only because of the plating thickness, but also because of how much attention was paid to the under-plating and gold plating processes, as well as the close relationship with the factory.
Even if the plating is done with the same 3-mill thickness in different plating factories, the quality can vary greatly depending on the factory. Therefore, I think that the quality of the wholesale company ultimately depends on how sensitive they are to this difference in quality and how much they pay attention to it.
So, it's important to not just look at the design and price, but how much the wholesale company cares about quality. Each wholesale company has a different level of attitude towards the production process and quality, so finding such wholesale companies is more important than looking at the wholesale price.
