a. Button size (ie, diameter size) Want to learn more about buttons: accessible Polyester Cotton,Cotton Polyester Fabric,Polyester Blend,Cotton Polyester Blend Fabric Suzhou Zhiqin Textile CO.LTD , https://www.zhiqintextile.com
That is, we often say 14#, 16#, 18#, 20#, 60# and so on! Its changing formula is: diameter = model * 0.635 (millimeter). If we have a button in our hand, but we do not know its size, we can use a caliper to measure its diameter (mm) and divide it by 0.635.
b. There is another way of expressing the size of the button: L
The conversion relationship is as follows:
Button size:
1L=0.635MM 1MM=1/25 inch INCH) Representation method unit: L, number (LIGNES)
14L = 8.89 MM = 11/32"
16L=10.16MM=13/32"
18L=11.43 MM =15/32"
20L=12.7 MM =1/2"
60L=38.1 MM =1-1/2"
c. Number of buttons and units:
PIECE PC.=1PC
Hit OZEN D.=12PCS
Luo GROSS G.=144 PCS
大罗GREAT GROSS GG.=1728PCS=12G
d, according to the material points:
Natural categories: real shell buckle, coconut buckle, wood buckle, bone buckle (common horn buckle), bamboo buckle, fruit buckle, fruit shell buckle, etc. Chemical categories: organic buckle, resin buckle, plastic buckle, combination buckle, urea Buckles, paint buckles, plating buckles, buckles, cloth buckles, buckles, and so on: Chinese knots, snap buckles, metal buckles, horn buckles, faux leather buckles, I-shaped buckles, denim buckles, magnet buckles, lasers Letter fasteners, vibration fasteners, etc., in the resin buckle, can be divided from the blank:
Bar buckles: pearl buckles, pattern buckles, regular bars, etc. Sheet buckles: pearlized corrugated sheets (including false-wave, true corrugated), pearlescent sheets, striped sheets, monochrome panels Manhattan: multicolored buckles, monochrome buckles f, from Holes:
Crimson deduction: Normally at the back of a button, it is radially perforated by a button.
Eye-catching clasp: Directly through the front and back of the button, there are generally four-button and two-button high buckles: on the back of the button, but there is a handle on the back of the button. There is a hole in the handle.
g, from the security method points:
Hand-stitching: Sewing directly to clothing
Snap button: use the mold to buckle on the clothes;
g, from the photometric points:
There is a light buckle, half-light buckle, no light buckle, matte buckle button manufacturing process of unsaturated resin + curing agent + + accelerant + color paste and mix - "" bar shop processing - "" bar blank ---" Blanking workshop--"Bucking workshop sheet blank shop processing--"Slab special buckle shop--"Buffing shop finished product shop A, bar material production process:
B, sheet metal production process:
C, the role of the blank and standard:
Excluding defective products before the next process 1 Blank thickness According to the company's requirements for the variety: Stick ± 0.2mm is genuine, board ± 0.1mm is genuine (qualified) is more than waste.
2 Colors, patterns change, do not meet the requirements of the species as waste.
3 models do poorly, rotten edges, pull heart, steam bubbles are waste.
D. Production requirements and standards of the deduction workshop 1 The shape and the sample are the same, including the size of the fine edge buckle, the back curvature, etc.
2 inspection standards, the following phenomena are waste:
a. Needle eye: The needle eye breaks, cracks, the eye hole is not in the center of the button, the four hole position is not square, the eye hole and the buckle surface are not perpendicular, after the broken needle, there are few holes or the needle is not penetrated, the front is big, the back is small, the dark eye Buckle, fringe edges, no holes, etc.
b. Buckle: One side is thick and one side is thin; the overall thickness of the button is correct, while one side is thick and one side is thin.
c. Compared with the sample buckle, the overall thickness is thicker or thinner in the overall button and there are thick and thin four consecutive buttons when the machine is turned.
E. Acceptance criteria for finished products a) Standard 1, color, pattern, model and sample of the finished product or the same requirements for the product.
2. The pinholes are positive and symmetrical, and the needle pitch and pinhole size meet the standards.
3, photometry meets the requirements.
4. There is no car-frying, no car-breaking, and uneven thickness on the back.
5, according to style, color, pattern, type packaging.
