Zipper rudimentary knowledge
First. Classify by material: Nylon zipper, resin zipper, metal zipper

   
1. Nylon zipper: Stealthy zipper, a pair of bone zipper, weaves the zipper, is the zipper, waterproof zipper are worn etc. insteading

   
2. Resin zipper: Gold (silver) Tooth zipper, transparent zipper, semitransparent zipper, domestic animal can give out light the zipper, flower bud penetrate the zipper, diamond zipper

  
3. Metal zipper: Aluminium tooth zipper, copper tooth zipper(  Brass, copper-nickel alloy, ancient copper, rose copper,etc.)  , black Le's zipper

  

Two. Classify by variety


1. Close the end zipper  2. Turn on tail zipper '  Left and right sides are inserted)  3.Pair closes the end zipper (X or O) 4.Pair opens the tail zipper '  Left and right sides are inserted) 

   

Three. Classify by specification and operate the craft

   

3 #s, 4 #s, 5 #s, 7 #s, 8 #s, 9 #s. . . . . . The size with zipper teeth of the size of type No. 20 is directly proportional to

   

Four. Now introduce the concrete technical indicator of the zipper

   

1. Stealthy zipper No. 3

   
It is thickness 2.10+0.05mm 2.65+0.03 wide to make 4.15+0.03 forms of width up

   
Electroplate and draw the head: Mouth wide 4.4mm mouth high 1.9mm

   
Bake the paint and draw the head: Mouth wide 4.35mm mouth high 1.85mm

   
Take the applicable thick surface fabric ordinarily; The lace is taken the applicable thin surface fabric.

   
Have stopping ordinarily: Advantage: The output is high '  Adjustable speed)  ; Shortcoming: Have and stop drawing roots sometimes

   
Stop on U type: Advantage: On stop it can pull by root to,is it the applicable demand clothes of pulling to root; Shortcoming: The output is low, 4000 / 8 hours.


It is apt to cause 3 #s  The factor of the substandard product of stealthy zipper:

   
The broadsword is curved; The department that shuts tooth of miaow is scratched slightly, cause and leave stopping welding it uncompletely while fixing inch, stop, emerge the miaow tooth, stop being easy to come off so too on being related; Take the lead to have size; There is no insurance after roast paint to draw the head.

   


2. Nylon zipper No. 3

   
It is thickness 2.00+0.05mm 2.65+0.03 wide to make 4.15+0.05 forms of width up

   
It is high to draw the head mouth: 2.05-2.15 It is wide to draw the head mouth: 4.2-4.25

   
Close the end:

    Do not need to divide the level miaow while fixing inch, so can turn back and open sometimes; Lay and stop deploying sometimes the latitude density is simply loose and apt to present the phenomenon of reeling off raw silk from cocoons, result in aesthetic problems, had better stop width cloth take pattern adopt first knit the law in the range, it is difficult to put and stop penetrating the cloth and take and reel off raw silk from cocoons like this; On stop by position because it is the neat, last 2.2mm ago, and then not last 1.8mm, in front and at the back of moulding plastics take the lead if wanting, guarantee yard by 4.0mm


Open end:

    Inch selects the tooth to be relatively difficult definitely, because the tooth distance is smaller (1.2mm) Had better select for use fixed yard put, right insert left to be high right low, need, build miaow by hand, ultra transliteration half a drop of miaow pigeonhole the root, both sides take shin distribute evenly, and pieces of line constant, punch cloth foot long about 8mm, pigeonhole pace that square draw at the socket should not be too fast, it is even for both sides to exert oneself and pull location to, keep organ must work while being slow, it is difficult for mould not to damage in this way, the pressure is transferred to under high pressure low-voltagely, slowly imprison the model, then the high-pressure movement pressure is transferred low-voltagely to the high pressure, go on, lock mould under high pressure, two reaction switches differ by about 20mm, because nylon No. 3 is relatively thin in thickness, so the switch movements of reaction are bad and relatively small, expect relatively much in adjusting the switch position of reaction, adjust the method specifically: Reaction turns on or off the light only as the noload position of zipper, go to the zipper miaow tooth and is higher than part, reaction pole movement, reaction turn on or off light put out, angle needle press, catch on, stick to cloth shut miaow hole of tooth put in place and wash.

   

It is apt to cause the factor of nylon zipper substandard product No. 3: Because of one yard of reasons put, a line is easy to be broken when fixing inch, half a drop of miaow ultra sound waves have not been killed, cause and press and open end and draw it uncompletely.

   
Note: Turn on 3 # nylon need it if accompanying, turn on unless there aren't tail, pretend yard normal tail,on stop can mould plastics
