Abstract
In an injection mold comprising a cavity and a gate for feeding a molding material into the cavity, the molding material fed from the gate into the cavity is divided into two streams that flow through the cavity and then meet at a confluent point so that the molding material portions are joined together along a joint plane. Two air vent gates are spaced apart from the confluent point so as to provide a larger area of the joint plane. Articles having a good outer appearance and improved strength at the material joint can be consistently manufactured to a high precision.
