What are the differences between the technical indicators of different types of resin zippers

Resin zippers can be used in various occasions, but are generally preferred for use in clothing pockets. It is a type of zipper that uses formaldehyde copolymer as the main material and has a cost between nylon zippers and metal zippers. This type of zipper has better durability than metal zippers and nylon zippers. Today, zipper manufacturers will share with you the technical specifications of different types of resin zippers. Resin zippers can be divided into 3 #, 5 #, 8 #, and 10 #, with different specific indicators:

3 # Resin Zipper:

Puller mouth height 2.6-2.7mm, mouth width 4.75-4.85 combination width 4.55+0.05 thickness 2.4+0.05.

Tail closing: when pressing up and down, the temperature, injection delay and pressure holding time should be adjusted properly. If the size of the tail closing zipper is about 15cm, if there is a certain number of tail closing zippers, two belts can be used to stop up. Similarly, if there is a suitable size, one belt can be used for the first mock examination.

Opening and closing: When sizing, it is important to ensure that the lead is sharp? FONT face="Times New Roman">4.5cm， (17 microphone teeth), the ultrasonic tape has clear patterns, uniform left and right, and is located about 1.5mm away from the microphone teeth, ensuring that the punching hook can be securely hooked and opened in a straight line.

Press adjustment: High pressure should not exceed 100kg/cm2, injection pressure should be 40kg/cm2, holding pressure should be 30kg/cm2, low pressure should be below 10kg/cm2, and the cooling time for high pressure and holding pressure should be at least 0.1 seconds.

5 # resin zipper

Pulling head height 3.2-3.3mm, mouth width 6.05-6.15, combined width 5.75+0.05, thickness 2.95+0.05.

Closing the tail: Please refer to 3 # resin closing the tail.

Opening and closing: Ensure that the head is 5cm (14 teeth) and the fine tooth head is 5.1cm (21 teeth). The ultrasonic tape pattern is clear and uniform on both sides, and the position is about 2mm away from the teeth. Ensure that the punching hook is firmly hooked and straight through.

Double opening tail: The ultrasonic tape is located about 2.5mm away from the microphone, and the rest is the same. If the resin zipper tape is pressed too deeply and then the tail is opened, the base of the tape is prone to breakage.

8 # Resin Zipper:

The height of the pull tab is 4.15-4.25MM, the width of the tab is 8-8.1, the combination width is 7.4+0.05, and the thickness is 3.9+0.05.

Opening and closing: The fixed size of the microphone head is 5.9-5.95 (14 teeth), and the fine tooth head is 5.55-5.6cm (23 teeth).

10 # Resin Zipper:

The height of the pull tab is 4.15-4.25MM, the width of the tab is 8.9-9, the combination width is 8.2+0.05, and the thickness is 3.95+0.05.

Opening and closing: Fixed size microphone head 6.05-6.1 (12 microphone teeth), the pressure should be adjusted higher on the basis of 5 #, and the time should also be adjusted longer to ensure that the square pin is full and smooth.

Adjustments should be made based on the actual product (zipper model).

Factors that are prone to producing defective products:

Exposed shin (due to whether the positioning pins of the upper and lower molds are broken and appropriate).

Pin detachment (whether the injection pressure is appropriate, and whether the holding and cooling time is sufficient).

Reduce the size of the square fabric seam (wait for the compressed zipper to cool before threading the zipper).
