1. Metal buckles:
(1) By function: square buckle / day buckle / activity day buckle / ring / oval ring / hook buckle (rotation and no rotation) / belt buckle and other special purpose buckle
With
(2) According to the electroplating method: the same metal puller
(3) Determine the fastener's specifications mainly by its width/height and wire diameter, special fasteners need to refer to the manufacturer's catalog, different manufacturers due to their different touch
There will also be differences in the products produced
2. Plastic buckle:
(1) According to the function points: Japanese buckle / square buckle / ladder buckle / buckle / hook buckle / multi-function buckle / rope buckle
Etc. and plastic reinforcing film
(2) According to the material: Commonly used for plastic steel and nylon material, nylon material price is higher
Standard class:
Metal mark
2. Branding, Branding Material PVC and Silicone (Silicon)
3. Cloth labels and satin labels: such as sample mark, placemark, CNC mark, etc.
others:
1.PE board E board is mainly used for bag inner molding, etc. It can be divided into recycled materials and new materials.
New materials can be divided into foaming and non-foaming
2. P-type tube, round tube: common specifications for 2mm/2.5mm/3mm/4mm, the difference between glossy/matt and hollow/solid
3. wheel wheel sets: to use with matching, material points PU and PP, etc.
4. Rod: The rod is mainly determined by its hand engine, Maza, A B long (A is the length after full deployment, B is the length after contraction), the number of knots
5. Molding film
Packaging:
1. The packaging material refers to the packaging material for the bag at the time of shipment, which includes the inside and the outside of the bag.
Two-sided packaging materials, internal production landmarks / elevators / hanging lines / needles, etc., external packaging including PE bags or PO
Bags/cartons (CTN), etc.
2. Calculation formula for the price of outer box (CTN): price=(length+width+2)*(width+height+1)*unit price/1000
Flat card calculation formula: price = (length + 0.5) * (width + 0.5) * unit price / 1000
First, the classification of fasteners
The buckles are generally divided into buckle series (also called side buckle), hook buckle series, rope buckle series, rubber feet series, clothing auxiliary materials series, five
Gold buckle series, tie rod series, tag series. Among them, the buckles, hooks, buckles, rubber feet, shoulder pads and hardware are commonly used by us.
Second, the various fasteners of the material, characteristics, uses and other
1, socket
The material of choice is generally POM (polyoxymethylene, commonly known as Saigang), PA and PC
The buckle is composed of a male buckle and a female buckle, and the two ends are respectively sewn with a webbing, and the length of the webbing is selected according to different needs, and is generally used for the shoulder,
Fix the waist. In order to more effectively play the role of buckles, there are now more convenient and scientific buckles have been introduced, such as the replacement of the invisible mother
buckle. This is a buckle that can be easily replaced without sewing a webbing. The other is a three-way buckle, the "Y" buckle, commonly used in baby carriages.
On the whole product, the female buckle can be designed according to the design and authorization of the client, and can also design the color mark or LOGO, and can also choose electroplating, silk screen printing, and colorful painting.
2, hook buckle
Its material is generally POM, PA, PP
In general, hook buckles, D buckles, press buckles, day buckles, square buckles, and ladder buckles are collectively referred to as a hook. Usually hooks and D buckles are used simultaneously, and the word is buckled.
The role of adjusting the length of the webbing, ladder buckle is generally used in the webbing end, plays a major fixed role, hook buckle can be electroplated, silk screen, generally in the ladder can be designed LOGO.
3, rope buckle
Its material is generally PA, PP, PC, POM
Rope mouth size, single hole and double hole, suitable for a variety of OO rope, nylon rope, elastic rope. And can design LOGO according to customer's request
4, rubber feet
Its material is generally derived from PVC
The rubber feet are divided into granular and strips, which are used in the bottom of the bag or box to effectively protect the goods from abrasion. They are indispensable materials for the box and have the function of anti-slip. The protection of the goods is not due to impact under special circumstances. damage.
5, shoulder pads
Made of PVC, PU, ​​TRP, TPE
The shoulder pad has functions of slowing down pressure and positioning non-slip. The front of the shoulder pad is called the back and the back is called the abdomen.
Handlebar is the most frequently used contact area. The webbing is embedded in the handlebars. It is firm and hard to move, so it can be adjusted in any color and can be set LOGO.
6, hardware
Material is generally POM
It is divided into hardware hook buckles, day buckles, square buckles, key chains, chains, zippers and so on.
Third, the buckle test.
There are two main aspects of fasteners in the testing process:
One is the pull test. This test is mainly used to detect the endurance of fasteners. It is divided into two steps:
1. Rally test, mainly used for buckles, D buckles, day buckles, etc.;
2, the lasting pull test, its main principle in the determination of the load of a certain weight, the buckle with the time value.
The second is the temperature test. This is mainly to test the endurance of fasteners at unconventional temperatures.
1, high temperature is usually set at 70 degrees Celsius
2, low temperature is usually set at minus 30 degrees
The time is 24 hours, according to different needs to carry out the appropriate value for testing, including the metal buckle but also on its anti-rust, anti-corrosion, resistance and other tests
