CXT526 processing and injection molding:
   1. Material preparation
CXT526 will be fully dry at the factory , moisture ≤1 ‰, packed by sealed bags. It can be used directly if the package is in good order.
   2. Material Storage
Under conditions of sealed, packaging is not damaged, it is best to store in dry warehouse with 25ºC. Because when storage temperature is higher than 25 ºC for long time,  oxidation will take place, yellow phenomenon will occur during the process, so it should be avoided.
   3. Drying
If he material is exposed to air for long time, it will absorb moisture in the air, and too high moisture will result in an overflow of molten material in the injection molding process state, containing air bubbles, and the injection of the product surface will cause waterlines.
The drying temperature (vacuum dryer)
Temperature: Maximum 100 ºC
Time: 6-10 hours
4. Requirements of machinery and equipment
Be sure to use nylon processing conditions of equipment, please.
    4.5. Screw
We recommend using the anti-wear protection, with a one-way valve nozzle, General Purpose (3-stage heating) screws.
Length: 18D-22D, compression ratio: 2-2.5
    4.6. Injection volume
Injection volume must be longer than shoot back in the absence of return flow metering.
Maximum mold filling capacity: approximately maximum injection volume × 0.5-0.9
    4.7. Heating section
Must and at least have three independent adjustment of temperature of the heating section, enough so that the temperature can reach 350 degrees, the feed nozzle temperature must be adjusted (cooling devices).
    4.8. Nozzle
Open nozzles are simple, good flow-ability, durable, but the screw through the metering section, it will produce intake air oxidation, it is recommended to adjust the nozzle needle.
    4.9. Clamping force
Generally you can use the following equation to calculate
7.5 kN1) x cavity projected area (cm²)
 4.10. Mold
Mold design principles are same as transparent thermoplastic plastic.
Typically cavity must use steel with hardness of 56HRC, wearing protective measures  is recommended in the high-speed flow mold portion.
    4.11. Gate and runner
In order to accomplish the desired end product feed and avoid contraction marks, it is recommended to set the gate in the center of the thickest part, pin point gate and tunnel gates are more economical, but the mold design requires a higher technical level.
    4.12. Gate size
0.8 × maximum wall thickness
    4.13. Runner size
1.4 × maximum wall thickness
    4.14. Exhaust
It must be considered adequate exhaust and suggested combining online increased exhaust measures, polishing, and the size of at least 0.2mm.
    4.15. Process Engineering
Filling, packing and feed
To make better product surface, combined with higher line strength, the best application of high injection speed, extended dwell time. Injection molding, injection speed should be properly adjusted to avoid the injection cycle late because speed is too high to produce fire phenomenon. If you use a low speed and low pressure, cooling time will be sufficient.
PS: Injection molding machine basic setting data
Temperature set as follows:
The feed section: 100 ºC
Heating section 1: 235 ºC
Heating section 2: 240 ºC
Heating section 3: 255 ºC
Nozzle: 240 ºC
Mold: 80 ºC
Melt: 245 ºC
 
Pressure speed setting as follows:
Injection speed: Middle ------High
Packing: 30 ------ 60 (unit: Mpa)
Back pressure: 0.5 -------- 1 (unit: Mpa)
Screw speed: 50 ------- 100 min-1
