1, saving round bar material, flat bar material:
The first material used, the current round bar, middle ring pile, is about 10mm wide and 8-9mm thick, while the flat bar is 12mm wide and 6-7mm thick, and the round bar is narrow and flat.
As far as the material is concerned, if you open a round bracelet, the same material will be much more than the flat one, plus ten pieces. Ten pieces of the same material can be cut out if the straight pile is leveled. If you do a straight pile round, there will be 12. The bracelet core of the round bracelet is not only thinner, but also smaller, because the round bracelet is about 2mm thicker and 2mm narrower than the flat bracelet.
That is to say, you can make a flat bracelet of 10 and a round bracelet of 12.
How many bracelets can be produced from a piece of material is the most primitive calculation method of gambling stone. From this point of view, round bracelets are actually more material-saving than flat bracelets.
However, the outer diameter of the round bar is 2mm larger than that of the flat bar. For example, the outer diameter of a round bracelet of 55 is equivalent to the outer diameter of a round flat bracelet of 57. Because the inside of the round bar is about 2mm thick.
Therefore, the bracelet core with a flat strip and a large circle can often be opened into a small circle.
And the bracelet core in the middle can also be divided into two to make a positive pile of flowers.
2, flat stick hand, round stick hand:
The round stick does not stick to the hand at all, because it is a raised round bone and will roll around on the hand. The flat strip sticks to your hand, so long as it is closed, it is comfortable to wear. Women today are different from those in ancient times. They don't have to do anything at home. Now they all have to do computer, driving, writing and housework. The comfort effect of wearing with or without hands is very different. For example, when you sleep, the bracelet is rolled on your arm, and the round bracelet will hurt, but the flat strap will not, and it will not hurt again.
3, the plane light intensity is large, and the circular light is small;
As far as smooth surface and fluorescence are concerned, the flat strip is wider and the smooth surface is larger, while both sides of the flat strip are flat and there is a big arc at the bottom, so the fluorescence will be concentrated on the whole bracelet body, and the water head of the seed will be more perfect because it is wide and thin, while the round strip is narrower, the smooth surface is smaller, and the radians at the top and bottom are smaller, so the mapping surface of fluorescence is much smaller.
As far as the design of perfect material is concerned, although there will be several flat strips, it will not only have the most comfortable wearing effect and the most beautiful and perfect appearance, but also have a perfect and thick bracelet core and tail material, and it is more likely to come with more rings (this is actually not the point or professional bracelets are basically not considered). Therefore, the gradual popularity of flat bracelets and the gradual withdrawal of round bracelets from the market are a kind of progress, not all of which are like the legend.
