No 8 two point teeth metal zipper two way is popular on bags and fancy garment.
Metal zipper two way have separated ends as well. The bottom slider allows movement from the bottom of the zipper. These zippers are used in rainwear, sportswear and sleeping bag.
UZIP ZIPPER is the biggest Metal Zipper, Heavy Duty Zippers and Zipper Puller manufacturer in Guangzhou of China.
Zipper Puller Styles
Auto lock
Typically used on jackets and coats, as well as pants and skirts. Auto lock sliders are manufactured with a small locking mechanism inside the body of the slider. This keeps the slider from moving on the zipper until the pull is grabbed and the locking mechanism is released.
Auto lock Bell Pull Auto locking slider with bell shaped pull. Large hole in pull makes it easy to attach a swatch of fabric or leather fob.
Auto lock Ring Pull Perfect Slider to use in applications where gloves are often worn or any other application where an easy-to-grab pull is required. Inside diameter of ring pull is 1".
Auto locks TS Pull Standard auto lock slider body with stylized pull in the shape of a toilet seat. Hence the name TS Pull.
Auto lock Wire Pull This slider may also be referred to as a "Stirrup" pull. Large wire pull allows for easy application of leather or fabric swatch of material to be tied onto pull.
Non lock Chain Pull Often used on pockets of coats and the inside of purses. This slider is not recommended for use on a separating (open end) zipper.
Non lock Double Pull Perfect slider for use on tents where access is required from inside and/or outside the tent. Also used on heavy canvas boat top covers. Double pull sliders are one slider with 2 pulls. Do not confuse double pull sliders with reversible sliders, they are quite different (Please see other slider choice
Non lock Long Pull Large pull with round hole at bottom of pull. The most common application for this type of slider is on backpacks and sports bags. Also suitable for tents and other outdoor gear.
Auto lock Single Pull Reversible This slider has one pull that "flips" around the slider body on a rail. The most common application is on reversible jackets.
Auto lock Double Pull This is the same as the Auto lock slider, however this has 2 pull tabs. This slider is typically used in the marine trades for heavy canvas boat tops, tents, and other applications where a double pull slider is required and the benefits of a locking slider are desired.
No 10 highly polished metal zipper with normal teeth is very smooth and rash guard.
Zipper Quality Control
Highly polished metal zipper, despite their numbers and practically worry-free use, are complicated devices that rely on a smooth, almost perfect linkage of tiny cupped teeth. Because they are usually designed to be fasteners for garments, they must also undergo a series of tests similar to those for clothing that undergo frequent laundering and wear.
A smoothly functioning zipper every time is the goal of zipper manufacturers, and such reliability is necessarily dependent on tolerances. Every dimension of a zipper—its width, length, tape end lengths, teeth dimensions, length of chain, slide dimensions, and stop lengths, to name a few—is subject to scrutiny that ascertains that values fall within an acceptable range. Samplers use statistical analysis to check the range of a batch of zippers. Generally, the dimensions of the zipper must be within 90 percent of the desired length, though in most cases it is closer to 99 percent.
A zipper is tested for flatness and straightness. Flatness is measured by passing a gauge set at a certain height over it; if the gauge touches the zipper several times, the zipper is defective. To measure straightness, the zipper is laid across a straight edge and scrutinized for any curving.
Zipper strength is important. This means that the teeth should not come off easily, nor should the zipper be easy to break. To test for strength, a tensile testing machine is attached by a hook to a tooth. The machine is then pulled, and a gauge measures at what force the tooth separates from the cloth. These same tensile testing machines are used to test the strength of the entire zipper. A machine is attached to each cloth tape, then pulled. The force required to pull the zipper completely apart into two separate pieces is measured. Acceptable strength values are determined according to what type of zipper is being made: a heavy-duty zipper will require higher values than a lightweight one. Zippers are also compressed to see when they break.
To measure a zipper for ease of zipping, a tensile testing machine measures the force needed to zip it up and down. For garments, this value should be quite low, so that the average person can zip with ease and so that the garment material does not tear. For other purposes, such as mattress covers, the force can be higher.
A finished sample zipper must meet textile quality controls. It is tested for laundering durability by being washed in a small amount of hot water, a significant amount of bleach, and abrasives to simulate many washings. Zippers are also agitated with small steel balls to test the zipper coating for abrasion.
The cloth of the zipper tapes must be colorfast for the care instructions of the garment. For example, if the garment is to be dry cleaned only, its zipper must be colorfast during dry cleaning.
Shrinkage is also tested. Two marks are made on the cloth tape. After the zipper is heated or washed, the change in length between the two marks is measured. Heavyweight zippers should have no shrinkage. A lightweight zipper should have a one to four percent shrinkage rate.

Inventions which may instead of zipper
It seems that there is always a need to open and close things repeatedly and quickly. The zipper does a very good job of that, but there are other inventions designed to do the same thing.
Have you ever packed a lunch to take on a trip? You may have used a Ziploc bag to keep your sandwich fresh. Ziploc bags are made of plastic and have male and female sides that lock together. Originally, Ziploc bags had only one seal, but now many have two. The seals are very tight and can be waterproof. Try doing that with buttons!
Another invention you are probably familiar with is Velcro. Velcro is usually made from nylon and has two sides. One side is called the hook side (it looks like a forest made up of tiny mushrooms). The other side is called the loop side (it looks like chain stitching made from nylon threads). When you press the two sides together, the hooks and the loops lock together to fasten the material.
