1.It will not appear the sink mark at the thick wall of the wing,rib,boss and other parts,improve
the plastic quality.
2.The required clamping force is 1/10 to 1/5 of the injection molding,can greatly reduce the
cost of the equipment.
3.The required cooling time is short, can shorten the molding cycle ,improve the efficiency
of injection molding.
4.Can reduce the height of plastic parts, reduce the cost of raw materials, to meet the
requirements of light-duty plastic industrial products.
5.As the molding injection pressure is low, the plastic residual stress is tiny,the plastic
not easy to appear buckling and crushing stress, can greatly reduce the rejection rate.
6.Can molding various kinds of complex plastics
The basic structure of gas-assisted injection molding and general injection mold is the
same .Because adopt the low pressure molding is beneficial to improve die life, but put
forward higher requirements on the shape accuracy of cavity surface.As these molding
methods can more realistically reflect the condition of the cavity wall surface, it is good
to the plastic with decorative pattern.But on the other hand,if the mold surface exist
some defects, also can be reflected from the plastic parts surface.
