I recently read the difference between "metal plating" and "plastic plating" on the Internet. After consulting the relevant information, I found that the relevant information is not complete. After reading most of the information, the differences between hardware plating and plastic plating are summarized as follows.
Process flow distinguishes plastic plating and plastic plating process: degreasing - hydrophilic - roughening - neutralization - prepreg - activation - degumming - chemical nickel - coke copper - acid copper - - Nickel--chromium metal plating process is: cleaning - electroplating copper sulfate - electroplating semi-gloss nickel - electroplating all-light nickel - electroplating chrome - drying materials difference metal plating substrate is metal, such as : Iron, zinc alloy, copper alloy, etc. The plastic plated substrate is plastic. Because the substrate is different, the process of the previous process is completely different, but the subsequent plating is basically the same. This is the difference found between the two materials.
The price difference is about the price of the two: depending on the material you use for plating, depending on the coating thickness requirements and test requirements, many factors will affect the plating price, for example: you have to give a plastic part with a small surface area Chrome plating is cheaper. It is more expensive to plate gold on a larger hardware, and the thickness of the coating directly affects the price. Therefore, it is necessary to analyze the problem according to the actual situation, and the two are not comparable.
However, if it is the same coating, plastic plating is more expensive, because the plastic plating process is a few more steps, and it is not easy to plate, the difficulty is relatively large, and the cost is naturally high.
The difference between the two characteristics of plastic plating is not conductive itself, you need to conduct conductive treatment, that is, activation and electroless plating, so that the surface is firmly attached to a metal film. There is no difference between it and the hardware plating.

Aluminium foil (or Aluminum Foil), often referred to with the misnomer tin foil, is aluminium prepared in thinmetal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.
Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner.
Aluminium is used for packaging as it is highly malleable and can be easily converted to thin sheets and can be easily folded, rolled and packed.it is also used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
