1 metal clip:
(1) by function: square buckle / day-shaped buckle / Day-shaped buckle / circle / oval ring / hook (rotating and non-rotating) / belt buckle buckle and other special purpose

Tool
(2) divided by plating method: with metal puller
(3) to determine the clip size depends mainly on the width / height and diameter, special fastener manufacturers need to refer to the directory, because different vendors with different raw touch

Production of the product will be different
2 Plastic Button:
(1) by function: date-shaped buckle / square buckle / ladder buckle / buckle / hook / multi-function button / Stopper
And plastic films such as reinforcement
(2) Material: commonly used for steel and nylon, nylon higher price
Standard class:
1 metal standard
2 brand mark, brand mark Material PVC and silicone (silicone)
3 standard cloth and satin standard: such as the sample standard, producing standard, CNC and other standard
Other categories:
1.PE board bag for E board is mainly used for forming such care can be divided into recycled materials and new materials, and
New materials can be divided into foam and non-foaming
2.P tube, round tube: common specifications for 2mm/2.5mm/3mm/4mm, a glossy / matte and hollow / solid difference
3 wheel wheel sets: To support the use of PU and PP Material
4 rod: rod to determine the main engine in its hands, cowboys, AB length (A after the commencement of full-length, B is the contraction length), number of sessions
5 die film
Packaging:
1 package material is used for the bag when shipped packaging materials, which includes the bag's internal and external
Two aspects of packaging materials, origin of the internal standard are / elevator / lift line / needle, etc., the external packaging, including PE bag or PO
Bags / carton (CTN), etc.
2 Carton (CTN) a price formula: a price = (length + width + 2) * (width + height + 1) * Price / 1000
Flat card formula: a price = (L +0.5) * (width + 0.5) * Price / 1000

A clip of the classification
Clips are usually divided into buckle series (also known as the open side buckle), hook buckle series, Stopper series, rubber feet series, clothing auxiliary materials series, five
Gold buckle series, rod series, tag series. Which buckles, hook buckles, cord locks, rubber feet, shoulder pads, hardware is used to.
Second, all the clip materials, properties, uses and other
1 jack
The choice of material is generally POM (polyoxymethylene, commonly known as just race), PA and PC
Buckle buckle and the female by the male buckle component, both ends of the suture belt, according to different needs and choose the length of webbing, generally used for shoulder,
Fixed waist. Buckle for a more effective role to play, now have more convenient and scientific buckle come out, such as replacement of the invisible parent
Buckle. This is a stitched webbing can not easily replace the buckle. Another direction for the three buttons, the "Y" type buckle, commonly used in infant car safety
All products, female buckle according to customer's design and licensing the design or color standard LOGO, you can choose plating, silk screening, painting.
2, hook buckle
The material is generally POM, PA, PP
In general, the hook buckle, D buckle, press buttons, Japan buckle, square buckle, hook ladder buckle collectively referred to as the mouth, the mouth hook is usually used simultaneously, and D buckle, buckle up on the word

Role in regulating the length of webbing, webbing ladder buckle is generally used in the end, play a major fixation, hook clasp can be electroplating, screen printing, usually in the ladder can be designed to wear LOGO.
3, Stopper
It's material is generally PA, PP, PC, POM
Optional port size diameter rope, single-hole and two holes for a variety of OO with the rope, nylon rope, elastic rope. Design according to customer requirements and LOGO
4 rubber feet
It generally comes from PVC material
Rubber feet are divided into granular and strip, with the bottom of the bag or box, to effectively protect items from wear and tear, is an indispensable material package with boxes, and has anti-skid function, the protection of goods in special cases not because of the impact damage.
5, pad
Made of PVC, PU, TRP, TPE
Pad with slow compression, positioning non-slip function, the front pad as the back, the abdomen is called negative
Hand is the most frequently used parts of the exposure, set to start the internal webbing, strong and easy to activities, it can be any color, and set LOGO
6 Hardware
POM material is generally
Into metal hook buckle, Japan buckle, square buckle, key chain, chain, zipper top.
Third, the buckle of the test.
Buckle in the testing process has two main aspects:
One is the tensile test, this test is testing the capacity of the clip, it is divided into two steps:
1, between the tensile test, mainly used for buckle, D buckle, buckle and so on;
2, persistent tension test, its main principle in determining the load of a certain weight, the clip is exposed time value.
The second is the temperature test, this is mainly to test unconventional buckle in temperatures of tolerance, is divided into two kinds of high and low temperature
1, the temperature is usually set at 70 degrees Celsius
2, low temperature is usually set at 30 degrees below zero
For 24 hours, according to different needs for the corresponding values were detected, of which the clip but also on its metal rust, corrosion, resistance testing, etc.
