Ecomaide6G30/33 all colors
Ecoamide6G30/33 is composed of 70/67% 6PA and 30/33% glass fiber.
- Molding Method;
- Shrinkage ;
Flow direction=0.2-0.4%, Vertical direction=0.4-0.8% (ASTM D955)
- Temperature Setting
Recommendable Mold Temperature;
*Above temperature is just only an example.
Please adjust each temperature case by case between 260℃ and 280℃.
80℃-90℃(In case of the water temperature control system)
*Before molding, gas venting system and a mold cavity must be cleaned with mold cleaner solvent.
Injection Pressure and speed setting;
Basically high pressure (around 90%) and high filling speed (around 90%)
are required for the excellent and glossy molded part surface. Additionally, Holding pressure is essential for PA,
as crystal polymer. (Actual filling time of chair base application is within 3 seconds and required holding pressure
time is at least around 15-20 seconds.) Recommendable holding pressure is around 30% and required holding
pressure time is 5seconds/1mm thickness. For example, 3mm thickness part requires 5 x 3 = 15 seconds.
Screw rotation at measuring;
In order to avoid glass fiber’s damage,
recommendable screw rotation speed should be less than 90rpm.
The key point of getting excellent molded part surface is material drying before molding.
0.2wt% of moisture is essential drying condition for the excellent molded part surface.
That drying condition will be achieved by 130℃ x 3hours of simple heating dryer or 80℃ x 3
hours of dehumidified dryer.
