How to measure buttons

Button measurement method: The most convenient way to measure the size of a button is the diameter measurement method; if you have a vernier, you can directly measure it. If you don't have a vernier ruler, you can lay the button flat on the table, put a ruler on the lower end of the button, put a ruler on the left and right, and a ruler perpendicular to the lower end of the button can be directly on the ruler on the lower end. Read the data. If the ruler is not enough, the left and right rulers can be replaced with other straight objects, and the ruler perpendicular to the lower end is sufficient.

We often say 14 #, 16 #, 18 #, 20 #, 60 # and so on! Its formula for changing the standard is: diameter = model * 0.635 (mm). If we have a button in our hands, but we don't know its size, we can use a caliper to measure its diameter (mm) and divide by 0.635. There is another way to express the size of the button, which is L. For example, 1L = 0.625MM 1MM = 1/25 inch INCH) means the method unit: L, number (LIGNES).

Button cost calculation method: When you enter the button industry, one more thing that you must understand is the cost calculation method of buttons. The so-called cost is known to all the production costs, such as raw materials, electricity, transportation and so on. Here I found a calculation formula: button cost = material cost of the button material loss cost processing cost (if the mold processing is the mold cost) labor cost management cost other costs (such as transportation).

The raw materials of metal buttons are mainly metals, and the raw materials can be weighed and calculated by weight: such as the weight of each copper button, the amount of copper per kilo, etc., it is easy to calculate the price of the material. In addition, when we consume inventory, we generally use the weighing method to calculate the cost.

Button inspection method: In our daily production of buttons, some unqualified buttons will inevitably appear. So how do we judge whether these buttons are qualified?
1. Control samples or confirm samples. See if the color and model match the sample;
2. There should be no cracks, nicks, unevenness or obvious scratches on the button surface;
3. There are no cracks or bubbles on the back; no rotten edges and uneven thickness;
4. the pattern should be no obvious deformation, no white eyes, white circles and other phenomena;
5. The buttonhole should be smooth and unobstructed; the needle eye must be punctured and ruptured, and be symmetrical and have no big eyes. If it is a dark eye clasp, the dark eye groove should be smooth and no obvious burst;
6. After electroplating or other processes, the effect should be uniform. If some special effects cannot be consistent, they can be packed separately
7. The color difference of the same batch of buttons should not be lower than the GB250 level 4 standard, and compared with the sample, it should not be lower than the GB250 level 3 standard;
8. Packing inspection, after the appearance inspection / customer required performance test is all qualified, then repacking. Certificates of conformity or other labels should be placed during packaging. The quantity of packaging shall be in accordance with the regulations, and the actual quantity of each bag shall be consistent with the regulations. If it is found that the tolerance is exceeded due to the difference in thickness or other reasons, it shall be fully inspected.

It is very necessary for those who join the button industry to grasp these professional knowledge. Buyers will undoubtedly choose professional manufacturers and high-quality buttons when purchasing buttons. Therefore, know more about the knowledge of the button industry and let your More professional service!
