In fact, metal eyewear plating color fall off is the problem of plating issue, it has nothing to do with metal eyewear. Usually the metal eyewear is required to be plated finished. Here we introduce several plating process for metal eyewear and their advantages and disadvantages.
Electrophoresis plating, commonly known as “water-plating”, it refers of coating mirror surface on metal eyewear by electrolytic method, more commonly used in normal alloy metal eyewear. To take example, stainless metal eyewear, nickel silver metal eyewear etc..
Advantages: low cost, and rich colors
Disadvantages: Very low coating adhesion, gold, silver, gun generally available for about a year; other colors generally can occur color fall off in 3-6 months.
Most Chinese eyewear supplier applies water-plating method coating metal eyewear.
Heavy gold electroplate–divided into “multi-layer texture coating method” and “the multilayer plating method” of two kinds. These two kinds of galvanization technological requirement is a natural metal color, thus the frame color is a single adopting of such processing, basically gold, silver major color.
The feature is coated with a thick 3.5UM gold or silver, generally available for about many years, no skin irritation and discomfort complaints.
IP vacuum ion plating: heat frame surface to form negative ions, free in a vacuum furnace, combined with the pigment particles through current electrodes to the lead adsorption on the surface of frame plating layer is formed.
Advantage: Eco-friendly, strong electroplated coatings adhesion, generally available for about many years without color falling off.
Weaknesses: color is gloomy, plating is not bright.
Multi-coated divided into spraying and paint two types.
A, spraying process: used for many students metal eyewear outer coating and covering.
Advantages: rich colors, bright
Disadvantage: prone to falling off and fading.
B, baking varnish technology: Used for fashion frames;
Advantages: coating thick, colorful and bright
Disadvantages: easy to scratch, color fall off.
There are various metal eyewear plating method, quality plating refers to electroplating equipment, materials, technology and other related factors, compared to other plating method, vacuum ion plating process is more complex, technical requirements for equipment are higher, so it is not easy to color falling off, the plating cost more expensive.
