A restrictive gate has a narrow entrance to the
cavityto restrict the amount of molten plastic in order to improve filling in the cavity.
The restrictive gate has the following characteristics.
Generates shear heat by going through the narrow gate, raising the temperature of molten plastic and improving the filling in the cavity.
Reduces residual stress, and thus reduces part defect such as warp.
As the cooling solidification time is shortened, molding cycle is also shortened.
As the gate trace is less, it is possible to complete finishing process in a short time.
