What are the classification of zipper?

Nylon zipper, resin zipper, metal zipper 1 according to material classification. Nylon zipper: Invisible zipper, double bone zipper, woven zipper, anti-zip zipper, waterproof zipper, etc. 2. Resin zipper: gold (silver) tooth zipper, transparent zipper, translucent zipper, animal light zipper, bud shot zipper, diamond zipper 3. Metal zipper: aluminum tooth zipper, copper tooth zipper (brass, copper, bronze, copper, etc.), black zipper zipper classification 1. Closed zip 2 . Open end zipper (left and right insert) 3. Double closed zipper (X or O) 4. Double open zipper (left and right insert)

According to the specifications and the operating process 3#, 4#, 5#, 7#, 8#, 9#... 20# model size is proportional to the size of the zipper teeth specific technical indicators zipper classification 1.3# invisible zipper combination width 4.15+0 .03 Single width 2.65+0.03 Thickness 2.10+0.05mm

Plated slider: mouth width 4.4mm mouth height 1.9mm

Painted pull head: mouth width 4.35mm mouth height 1.85mm

Ordinary straps are suitable for thick fabrics; lace straps are suitable for thin fabrics.

Ordinary top stop: Advantages: High output (adjustable speed); Disadvantages: The top stop sometimes does not pull the root U-shaped top stop: Advantages: The top stop can be pulled to the root, applicable to the garment that requires pulling to the root; Disadvantage: Low output, 4000 bars/8 hours.

Factors that can easily cause 3# invisible zipper defects:

Big knife bend; when the inch is fixed, the teeth of the microphone are cut open slightly, which causes the bottom welding to fail. The joints also expose the teeth, so that the upper body is easy to come off; the length of the lead is long; the head is not covered by insurance after painting.

2.3# nylon zipper combination width 4.15+0.05 single width 2.65+0.03 thickness 2.00+0.05mm

Head height: 2.05-2.15 Pull head width: 4.2-4.25

Closing:

No need to divide the high and low microphone, so sometimes adjustable head open; hit the end of the cloth sometimes weft density is easy to appear partial spinning phenomenon, affecting the appearance, it is best in the next stop width within the cloth pattern with a weave method, In this way, it is not easy to pull through the cloth; the top stop position must be flush, the front head is 2.2mm, and the rear head is 1.8mm. The front and back of the code must be 4.0mm.

Opening:

Fixed teeth selection is more difficult, because the pitch is relatively small (1.2mm) so it is best to use a fixed code, right insert left high right low, need to manually repair the microphone, ultra-thin half of the microphone to the root, with both sides of the distribution Evenly, and the surface line is constant, the punching cloth foot length is about 8mm, the speed of pulling the square block plug should not be too fast, both sides force evenly and pull in place, the pressure mechanism must be effective, so that the mold is not easy to damage, the pressure is transferred from high pressure For low pressure, slowly close the mold, and then the high pressure action pressure from low pressure to high pressure, high pressure mold clamping, the two induction switches can be about 20mm difference, because 3 # nylon thickness is thinner, so the sensor switch movement is less, on the Adjusting the position of the sensor switch is highly demanding. The specific adjustment method is: when the zipper is in neutral, the sensor switch lights up, goes up to the zipper microphone tooth, the sensor bar moves, the sensor switch lamp goes off, the fishing needle presses down, and the fishing needle pushes down. The teeth of the microphone teeth flushed into place.

Can easily lead to 3 # nylon zipper defective factors: due to code reasons, when the inch line is easy to break when the inch, ultrasonic half a microphone did not die, causing the pressure to open the tail is not in place.

Note: 3 # nylon tail need to accompany open end pull head, if the code is installed normally, the upper end can be injection 1.5# nylon zipper pull mouth height: 2.9-3.0 mouth width: 6.5-6.6 combination width: 6.45+0.05 single width :4.15+0.05 Thickness: 2.70+0.05

Ordinary open end: fixed-inch gear selection according to different code installed at any time (due to changes in tooth pitch), to ensure the right high-left low right insert, left the other way back, ultra-thin half-inch microphone to the root, the location of the tape should be flush Make sure that the pin hole of the pin block rushes to the end, and the hole length of the punching pin is about 9.5mm, ensure that the pin block is mounted to the root, the pin pin penetrates in the punching block, the block band must be clamped on one side, and the punch pin penetrates .

When repairing and disassembling the mold, be sure to pay attention to the tilt of the die, that is, insert the left high and right low, and vice versa, and perform strong testing.

The factors that are prone to defects are: due to the short or long opening of the fabric, the strength is not enough, the square of the bolt is not installed, the square head is flawed, and the strength is not up to the standard value. The lateral side of the banding tendon is too deep to cause a rupture of the band.

Injection molding open end: fixed inch, supersonic same as above, need to open the mold to open, (Note: when changing the mold, pay attention to the starting position, because the mold stroke is not the same, otherwise it is easy to damage the mold), the specific adjustment can be put into the mold with a piece of paper In the hand wheel, the paper is just cut off, the punching leg length is 9.5mm, press the square block pin, please refer to the 3# nylon tailing press 1.5# nylon double tail 1 inch inch supersonic with 5# nylon zipper, hit The hole of cloth is about 13cm long, and the square plug is installed to the root. The four pinholes are respectively centered and penetrated. The square must fall into position. Otherwise, it is prone to defective products, and the separate parts and the slider must be matched. In case of special sliders, it is recommended Before the production of large goods, whether it is matched or not, if the needle is punched out of the center, or if the separated part is broken, the surface of the punching needle will be back-pressed in different directions.

2.3# resin zipper pull mouth height 2.6-2.7MM, mouth width 4.75-4.85 combination width 4.55+0.05 thickness 2.4+0.05

Closing: When pressing up and down, the temperature, injection delay, and pressure holding time must be adjusted properly. If the closed zipper size is about 15CM, a certain number of rows can be used to arrange the microphone and the mold. If you have the right size, you can also mold one.

Opening: To ensure that you take the lead when ordering? FONT face="Times New Roman"> 4.5cm, (17 tablets of teeth), ultrasonic tape pattern is clear, left and right uniform, about 1.5mm from the microphone teeth to ensure that the punch crochet hook, and the word open.

Press adjustment: high pressure to not exceed 100kg/cm2, injection pressure 40kg/cm2, pressure 30kg/cm2, low pressure 10kg/cm2 below, high pressure, pressure cooling time should be 0.1 seconds or more, according to the actual product (zipper type ) Then adjust it.

Defective factors are prone to:

Lucy (The reason is whether the upper and lower die positioning pins are broken or not)

The pin is detached (whether the injection pressure is proper or not, and the pressure and cooling time are sufficient)

Small cloth seams close (pressed zipper to be cooled before wearing the slider)

1.5# resin zipper pull mouth height 3.2-3.3MM, mouth width 6.05-6.15 combination width 5.75+0.05 thickness 2.95+0.05

Closing: Please refer to 3# Resin Closing and Tailing: Adjust the inch to ensure that it takes the lead 5cm (14 tablets), fine teeth lead 5.1cm (21 tablets), supersonic tape pattern is clear and uniform, position away from the teeth 2mm or so, to ensure that the perforated crochet hook firmly and word open double tail: ultrasonic tape position from the microphone teeth about 2.5mm, the other, the resin zipper tape if the pressure is too deep, and then after the open end, the tape is easy to break the root .

1.8# resin zipper:

Pull head high 4.15-4.25MM, mouth width 8-8.1 combination width 7.4+0.05 thickness 3.9+0.05

Opening: fixed-inch microphones take the lead 5.9-5.95 (14 tablets of teeth), fine teeth take the lead 5.55-5.6cm (23 tablets of teeth)

2.10# resin zipper pull mouth height 4.15-4.25MM, mouth width 8.9-9 combination width 8.2+0.05 thickness 3.95+0.05

Opening: fixed-inch microphones take the lead 6.05-6.1 (12 tablets), the pressure should be raised on the basis of 5 #, and the time is also adjusted to ensure that the square plug full and smooth.

3.3# metal zipper pull mouth height 2.1-2.2MM, mouth width 4.55-4.65 combination width 4.45+0.05 thickness 1.95+0.05
