How to determine the various buttons?
There are many kinds of buttons, and there are many different kinds of materials. Let's look at how to distinguish the buttons under different materials.
Button materials can be divided into plastics (resins, plastics), metal buckles (copper, iron, alloys), natural types (shells, wood, coconut shells, bamboo. Buttons are made of various materials, the process is not the same Some of the buttons look the same, and even the people in the trade do not share the same vision with their eyes, so destroying and scratching the coat can make the difference.
For example, plastic and resin buckles, and plastic (including various plastic) buttons are generally die-cast, so there will be a line on the edge of the button. This mold line may be removed by some factories during subsequent processing. , but his weight is lighter than the resin (some plastics will weigh).
The resin buttons are mechanically sculpted and then polished, so the surface is not full-lined and is very clean. But he is fragile, his face is easily scratched, and it gets soft in boiling water.
The other is copper and iron material buttons, this one will know with a magnet, and there is a hard object to scrape off the surface plating layer, the brass color (gold) in the copper buckle surface. The iron buckle is black and this is the color of the raw material.
The alloy buckle is relatively heavy and is made by die-casting. All the mould lines are generally polished and polished and may not be visible, but he is very heavy and solid.
The above is the way to judge the buttons of different materials. I believe that when you select the buttons later, you can roughly identify the material of the buttons.
