Analysis of the difference between metal plating and plastic plating
What is the difference between metal plating and plastic plating?
One, the difference between hardware and plastic plating materials
The base material of metal plating is metal, such as iron, zinc alloy, copper alloy, etc. The base material for plastic plating is plastic. Due to the different substrates, the processes processed in the early stage are completely different, but the subsequent electroplating is basically the same. This is the difference found from the two materials.
2. The difference in the price of metal plating and plastic plating
Regarding the price of the two: it depends on what material you use for the plating layer, as well as the plating thickness requirements and test requirements. Many factors will affect the plating price, such as: you need to give a plastic part with a small surface area Chrome plating is cheaper, while gilding a larger piece of hardware is more expensive, and the thickness of the plating directly affects the price. Therefore, it is necessary to analyze the problem according to the actual situation. The two are not comparable. (Guide: What is the inherent difference between electro-galvanizing and hot-dip galvanizing (hot-dip galvanizing)?)
However, if it is the same coating, plastic electroplating is more expensive, because the plastic electroplating process is a few more steps, and it is not easy to plate, which is more difficult, and the cost is naturally high.
Three, the difference between hardware and plastic electroplating process
The process of plastic electroplating and plastic electroplating is: degreasing-hydrophilic-roughening-neutralization-prepreg-activation-debonding-chemical nickel-pyro copper-acid copper- -Nickel--Chromium
The process of metal electroplating is: cleaning--plating copper sulfate---plating semi-gloss nickel---plating full-gloss nickel---plating chromium--drying
Fourth, the difference between the characteristics of hardware and plastic plating
The characteristic of plastic electroplating is that it does not conduct electricity. It needs to be electrically conductive first, namely activation and electroless plating, so that a layer of metal film is firmly attached to the surface. After that, it is no different from metal plating.
