What is the reason for the deformation of carbon fiber reinforced nylon injection molded parts?
1) Lengthen the injection time to prevent the resin from flowing back before the gate is solidified due to the short molding cycle, and it is difficult to fill the cavity.
2) Increase the injection speed.
3) Increase the mold temperature.
4) Increase the resin temperature.
5) Increase the injection pressure.
6) Expand the gate size. Generally, the height of the gate should be equal to 1/2 to l/3 of the wall thickness of the product.
7) The gate is placed at the maximum wall thickness of the product.
8) Set the exhaust groove (average depth 0.03mm, width 3~smm) or exhaust rod. It is more important for smaller workpieces.
9) A certain (about smm) buffer distance is left between the screw and the injection nozzle.
10) Use low viscosity grade materials.
11) Add lubricant.
