Closed tail: 3# nylon zipper is not necessary to divide the height and the low meter when fixing the inch, so sometimes the head can be opened; sometimes the edge density of the cloth edge is loose and the spinning phenomenon is easy to occur, which affects the appearance. It is better to use the cloth pattern in the lower width range. Weaving method, so that the lowering of the penetration tape is not easy to draw; the upper stop position must be ensured to be flush, the front lead is 2.2mm, the rear lead is 1.8mm, and the front and back of the injection code must be 4.0mm.

Opening: 3# nylon zipper is difficult to select the teeth. Because the tooth distance is relatively small (1.2mm), it is best to use the fixed code. The right insert is left high and the right is low. You need to repair the microphone by hand. The super sound is half pressed to the root. The belt is evenly distributed, and the upper thread is continuous. The length of the perforated cloth is about 8mm. When the square block is inserted, the pulling speed should not be too fast. The force on both sides is even and pulled into place. The pressing mechanism must be effective, so the mold is not easy to be damaged. From high pressure to low pressure, slowly cut the mold, then the high pressure action pressure is changed from low pressure to high pressure, and high pressure clamping is performed. The difference between the two induction switches is about 20mm. Because the thickness of 3# nylon is thin, the difference between the induction switch is worse. Small, the position of the adjustment sensor switch position is higher, the specific adjustment method: When the zipper is in neutral, the sensor switch light is on, go to the upper part of the zipper microphone, the sensor rod moves, the sensor switch light is off, the fishing needle is pressed, hooked The hole of the patch and the tooth is flushed in place.

Factors that easily lead to 3# nylon zipper defective products: Due to the reason of the code loading, the upper thread is easy to break when the inch is fixed, and the ultrasonic half-microphone is not pressed, causing the pressure to open the tail.

Note: 3# nylon open tail needs to be accompanied by the tail puller. If the code is normal, the upper end can be injection molded.
