In the realm of plastic products manufacturing, especially in plastic injection mold design and plastic molding design, the submarine gate (also known as the hidden gate) is a crucial element in Injection molds for plastics.
The submarine gate is a concealed gate structure. The gate location is usually hidden inside the plastic part, on ribs, bosses, or non - appearance surfaces. During mold opening or ejection, the gate can be automatically cut off by mechanical force without the need for subsequent manual trimming.
This type of gate is an ideal choice for scenarios in plastic parts production that prioritize appearance and require automated production. It is especially suitable for small - to - medium - sized, multi - cavity plastic parts with high appearance requirements in plastic products manufacturing. However, it should be noted that in plastic injection mold design and plastic molding design for Injection molds for plastics, the submarine gate depends on the structure of the plastic part and the fluidity of the plastic. During the design process, issues such as stress concentration and debris need to be avoided through dimension optimization and mechanism coordination.
