The Handbag Factory Knowledge You Must Have

I.  Metal buckle

 (1) According to the function: square buckle / tri-ring buckle / adjustable tri-ring buckle/ ring / oval loop / hook buckle (rotating and non-rotating) / belt buckle and other special-purpose buckles.

 (2) According to the electroplating method: the same as the metal pull tab.

 (3) The specifications of the fasteners are mainly determined by their width/height and wire diameter. For special fasteners, refer to the manufacturer's catalog. Different manufacturers may produce different products due to their different exploration tools.

II.Plastic buckles

 (1) According to the function: Tri-ring buckle/square buckle/ladder buckle/insert buckle/hook buckle/multi-function buckle/cord buckle and other plastic reinforcing sheets.

 (2) According to the material: the commonly used plastic steel and nylon materials are more expensive.

First, the classification of buckles

  Buckles are generally divided into buckle series, hook buckle series, rope buckle series, rubber foot series, garment auxiliary material series, hardware buckle series, pull rod series, hangtag series, etc. Among them, buckles, hooks, rope buckles, rubber feet, shoulder pads, and hardware are commonly used.

III.The materials, characteristics, uses, and others of various fasteners

1. Socket

 The selected materials are generally POM, PA, and PC

 The buckle is composed of a male buckle and a female buckle, and the two ends are sewn with webbing respectively. The length of the webbing is selected according to different needs. It is generally used to fix the shoulders and waist. To play the role of the buckle more effectively, there are more Convenient and scientific buckles that came out, such as the invisible female buckle for replacement. This is a buckle that can be easily replaced without sewing the webbing. The other is a three-way buckle, that is, a "Y"-shaped buckle, which is often used on baby stroller safety products. The female buckle can be designed with color labels according to the customer's design and authorization. or LOGO. You can also choose electroplating, silk screen printing, and color painting.

 2. Hook

  Its materials are generally POM, PA, and PP.

  Generally speaking, hook buckle, D buckle, press buckle, tri-ring buckles, square buckle, and ladder buckle are collectively referred to as hooks. Usually, hooks and D buckles are used at the same time. The tri-ring buckles play the role of adjusting the length of the webbing. At the end of the webbing, it plays the main fixing role. The hook button can be electroplated and screen printed. Generally, a LOGO can be designed on the ladder button.

 3. Cord buckle

  Its materials are generally PA, PP, PC, and POM.

The diameter of the rope opening can be selected first, single hole and double hole, suitable for all kinds of OO rope, nylon rope, and elastic rope. LOGO can be designed according to customers’ requirements.

 4. Rubber feet

 Its material is generally derived from PVC.

 Rubber feet are divided into granules and strips. They are used at the bottom of bags or boxes to effectively protect items from wear and tear. They are an indispensable material for bags and have anti-skid functions to protect items from impact under special circumstances. and damaged.

 5. The material is PVC, PU, TRP, and TPE.

 The shoulder pad has the functions of reducing compression and positioning and is anti-skid. The front side of the shoulder pad is called the back, and the reverse side is called the abdomen.

 The handle is the part that people use most often. The webbing is embedded in the handle, which is firm and not easy to move. It can be colored arbitrarily and LOGO can be set.

 6. Hardware

 The material is generally POM.

 Divided into hardware hook buckle, tri-ring buckles, square buckle, key chain, chain, zipper head, etc.

IV.The test of the buckle

 There are two main aspects of the buckle in the testing process:

 One is the tensile test. The main work of this test is to detect the bearing capacity of the fastener. It is divided into two steps to complete:

 1. Inter-tension test, mainly used for buckles, D buckles, tri-ring buckles, etc.

 2. Durable tensile test, its main principle is to determine the time value of the buckle when a certain weight is loaded.

 The second is the temperature test, which is mainly to test the bearing capacity of the fastener under unconventional temperatures, which is divided into two types: high temperature and low temperature:

 1. The high temperature is usually set at 70 degrees Celsius

 2. The low temperature is usually set at minus 30 degrees

 The time is 24 hours, and the corresponding values can be tested according to different needs. Among them, the relevant metal fasteners should also be tested for rust resistance, corrosion resistance, drug resistance, etc.
