Classification Of Buttons
1. Button button size (that is, diameter score) is what we often call 14 #, 16 #, 18 #, 20 #, 60 # and so on! Its label replacement formula is: diameter=model * 0.635 (mm). If we have a button but do not know its model and size, we can measure its diameter (mm) with a caliper and divide it by 0.635.
2. By material:
Natural: scallop buckle, coconut buckle, wood buckle
Chemical industry: organic buckle, resin buckle, plastic buckle, combination buckle, urea buckle, paint buckle, electroplating buckle, etc
Others: Chinese knot, four snap fastener, metal buckle, cow corner buckle, imitation leather buckle, laser letter buckle, vibration buckle, etc
3. In the resin buckle, it can be divided from the blank:
Bar buckle: pearlescent buckle, pattern buckle, ordinary bar, etc
Plate buckle: pearlescent corrugated plate (including false ripple and true ripple), pearlescent plate, striped plate and monochrome plate
