Materials can be divided into plastic buttons (resin, plastic), metal button type (copper, iron, alloy), a natural class (shell, wood, coconut shell, bamboo. A variety of materials to make buttons, processes are not the same and some buttons, looks like even the industry people with the eyes may not be able to distinguish, so the damage, scratch coat to distinguish.
Distinguish between plastic and resin buttons buttons buttons, plastic buttons and resin button, plastic (including plastic) buttons are generally made of die-casting, so the buttons will have the edge of a line, the parting line, some factories may removed in subsequent processing of this line, but his weight will be lighter than some of the resin (of course, some special plastic would weight). Carved resin button is mechanical, then polished, so the surface is not the whole model line, very smooth. But his fragile, easily scratched surface, placed in boiling water will become soft.
How to distinguish between copper and iron buttons buttons? : Copper and iron materials, buttons, magnets a try with this know, there are electroplated with a hard object scrape the surface layer, the surface where the brass buckle (gold). Iron buckle is black, which is the color of raw materials.
How to determine to determine the alloy buttons? : Relatively heavy alloy buckle is made of die-casting, all model lines, usually to do grinding and polishing process, may not see, but his heavy weight, is solid. |
