How to solve the problem of air bubble in glass fiber reinforced PA6 injection molding machine?
1., the temperature of the sol is reasonable, it is recommended to try at 260-280 degrees;2. sol pressure is suggested to increase properly at 30par and screw speeds;3., mold temperature is too cold, but also easy to cause crazing, mold temperature needs more than 80 degrees;4. bake temperature recommended at 100-120 degrees, baking 4 hours
Strengthening PA6 is to add 30% glass fiber in PA. The mechanical properties, dimensional stability, heat resistance and aging resistance of PA are obviously improved, and the fatigue strength is 2.5 times that of unreinforced. The forming process of glass fiber reinforced PA is approximately the same as that without strengthening, but the injection pressure and injection speed should be increased properly, and the barrel temperature can be increased by 10-40 degrees.
