Jan 2, 2018 · The four most common types of tunnel gate designs are (r-l) eliptical gate, D-gate, ball-gate and chisel gate. An angled, conically shaped tunnel gate, also known as a subgate or submarine gate, is one of the best—and worst—types of gating methods.
Jan 6, 2023 · 3. Submarine Gates. The submarine or tunnel injection molding gate is usually placed below the mold parting line, facilitating automatic trimming during component ejection. It involves using a narrow channel that joins the cavity near the parting line, filling the cavity from below the parting line.
The tunnel gate (submarine gate) is used very frequently as a type of gate having a structure that automatically cuts the molded item and gate at the time of opening and closing the parting surface.
Feb 24, 2021 · The submarine gate is an injection molding gate-type used in two-plate molds. It uses an angled and tapered channel that meets the cavity near the parting line, filling the cavity from underneath the parting line.
Submarine Gates Also known as tunnel gates or sub-gates, this injection molding gate design involves directing plastics to the cavity’s edge below the parting line. Thus, it ensures that the trimming of the gate occurs automatically.

Submarine or Tunnel Gate. The tunnel or submarine injection molding design allows the flow of plastic material to the cavity edge below the parting line. This gate configuration allows easy automatic trimming (degating) before ejection. It is the go-to gate design for small components and high cavitation molds, requiring automatic trimming.
May 19, 2023 · Submarine Gate, also known as a Tunnel Gate, is an advancement of the Pin Gate design that addresses the complexities of Pin Gate molds while retaining their benefits. It provides flexibility in the placement, allowing for positioning on either the moving or fixed mold side.
Jul 10, 2023 · Gates come in various designs, including edge gates, sub gates, and direct sprue gates, which we will discuss further below. Proper gate selection and placement are crucial for achieving uniform filling of the mold, minimizing defects, and optimizing the production of high-quality plastic components.
Decide whether to use a pinpoint gate (which requires a mold made from three components), a submarine gate (which eliminates the need for finishing) or an ordinary gate. Ⅳ. Based on the moldability of the material
