70cm/75cm Open End Atuo Lock Invisible Nylon Reversible Zipper For Jacket

Zipper is a connecting piece that combines or separates articles by means of continuously arranged chain teeth. It is now widely used in clothing, bags, tents and so on.

nylon zipper
Combined width 4.15 ± 0.05, single width 2.65 ± 0.03, thickness 2.00 ± 0.05mm
Pull head opening height: 2.05-2.15 pull head opening width: 4.2-4.25
Closed tail: there is no need to divide the height when setting the inch, so it can be opened by turning the head sometimes; Sometimes, the weft density of the cloth edge is too loose, which is easy to lead to wire drawing and affect the beauty. It is best to use one-up-down weaving method for the pattern of the cloth belt within the width of the bottom stop, so that the bottom stop penetrates the cloth belt and is not easy to wire drawing; The top dead end position must be flush. The front head shall be 2.2mm, the rear head shall be 1.8mm, and the code head before and after injection molding shall be 4.0mm.

Tail opening: it is difficult to select the fixed size teeth. Because the tooth spacing is relatively small (1.2mm), it is best to select the fixed code installation.

The right insert is high on the left and low on the right. The microphone needs to be repaired manually. The ultrasonic half microphone is pressed to the root. The shins on both sides are evenly distributed and the surface line is continuous. The length of the perforated cloth foot is about 8mm. The pulling speed when pressing the square bolt should not be too fast. The force on both sides is uniform and pulled in place. The pressing mechanism must work when it is slow, In this way, the mold is not easy to be damaged, the pressure changes from high pressure to low pressure, the mold is closed slowly, and then the high-pressure action pressure changes from low pressure to high pressure, and the high-pressure mold is locked. The difference between the two induction switches is about 20mm.

Due to the thin thickness of 3# nylon, the action difference of the induction switch is small, and the requirements for adjusting the position of the induction switch are high, Specific adjustment method: when the zipper is in neutral, the sensing switch light is on, go to the part where the zipper's teeth are higher, the sensing rod acts, the sensing switch light is off, the fishing needle is pressed down, hook the hole sticking to the cloth and closing the teeth, and rush down in place.
Factors that easily lead to 3# nylon zipper defective products: due to the code loading, the surface line is easy to break during sizing, and half of the ultrasonic microphone is not crushed, resulting in inadequate pressing and tail pulling.
Note: 3# nylon tail puller shall be accompanied with the tail puller. If the code loading is normal, the top stop can be injected.
