Zipper Puller MIM Parts

Product Introduction

The structure of the zipper head
In general, there will be a model and serial number on the zipper. Usually 5 means that this is a No. 5 zipper, and h and d represent the model number for easy traceability. Once there is a problem with the zipper head of h or d, it can be traced back to the problem with that mold and that slider.
Zipper puller MIM Parts is a connecting piece that relies on the continuous arrangement of chain teeth to merge or separate items. It is now widely used in clothing, bags, tents, etc. The zipper is composed of chain teeth, sliders, upper and lower stops (front code and rear code) or locking pieces. Among them, the chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, the zipper has two chain belts, and each chain belt has a row of chain teeth respectively, and the two rows of chain teeth are arranged alternately. The slider clamps the chain elements on both sides, and slides with the help of the pull tab, so that the chain elements on both sides can be engaged or disengaged from each other.
This zipper is composed of a fixed block, a zipper strip, a zipper puller, a pull block, a fixed frame, a fixed groove, a snap block, a snap groove and a rotating shaft. Set on the zipper bar; the hand-pull block is set in the middle of the zipper head through the rotating shaft, and the upper part of the hand-pull block is set as a fixed frame; the snap block is set at one end of the fixed block through the rotating shaft, and the other end of the fixed block is set as a snap groove. The buckle block is matched with the snap groove; the lower part of the snap block is set as a fixing groove, and the fixing frame is matched with the fixing groove.
Although the production cost of the zipper disclosed in this patent is low, the structure of the zipper is too simple and can only be used in a simple environment. Therefore, it is necessary to design a zipper.

Zipper Shape
1. Straightness of the zipper
The test method for the straightness of the zipper is as follows: take a finished zipper, place it flat on a flat platen, make it in a natural state, then use your fingers to move back and forth along the sides of the chain teeth once, and use a ruler to gradually move closer to the bend , and then use another ruler to measure the distance between the chain tooth foot and the ruler, this distance is the straightness.

2. The strength of the zipper
The strength of the zipper is the most important performance index, which determines the scope of use and durability of the zipper. In the zipper standards of various countries, there are clear regulations on the strength, which is also the basis for testing the quality of the zipper. Different specifications and models of zippers have different strengths. For different purposes, the zipper supplier will generally give a reference selection of specifications and usage ranges. The specifications and models of the zipper must meet the requirements of use. Once confirmed, the specifications and models must meet the requirements of the order.

3. Specifications of the zipper
The specification of the zipper refers to the width and size range of the tooth chain after the two teeth are combined. The unit of measurement is millimeters. The specification of the zipper is the basis for the shape and size of each component and is the most characteristic important dimension. The type of the zipper chain is the shape , an important reflection of the structure and performance characteristics, the chain model of the zipper not only includes the specification requirements of the zipper chain, but also reflects the performance characteristics of the zipper chain, that is, the technical parameters and functions of the zipper.

4. The color of zipper and zipper tape
The color of zipper and zipper tape must conform to the confirmation sample card and return to the confirmation sample. If it is required to match the body color, it should be checked again with the fabric, and at the same time check whether there is any color difference between the same zipper and the same batch of zippers. Generally, it should be above GRADE3 .

Where is the zipper?
1. First of all, the tools are ready, such as sliders, screwdrivers, and pliers.
2. From the sliders, choose one with the same bottom, and compare whether it is suitable.
3. Use a screwdriver, insert it from the middle of the bottom, and break it down hard.
4. Take any part of the zipper and insert the slider obliquely.
5. Use the same method on the other side. After installation, check that the zippers on both sides are inside the slider, press the slider with your hand, and clamp the bottom with pliers.
6. After pulling the slider to one side, pull it up gently. If the zipper at the junction with the cloth surface is separated, close the first few zippers with your hands, and then pull it up.
7. After replacing the Zipper puller MIM Parts, although it is different from the factory zipper, it can still be used normally.
