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.
Jun 21, 2024 · Submarine gates, also known as tunnel gates, are an injection molding gate type that uses an angled and tapered channel to meet the mold cavity near the parting line, filling the cavity from underneath.
Nov 27, 2023 · A sub gate in tooling mold, also known as a submarine gate, tunnel gate, is a type of gate used in injection molding. It is a small secondary gate that is located below the parting line of the mold.
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.
1 day ago · 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.
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
A tunnel gate (submarine gate) is used very frequently as a gate method for a structure that automatically cuts the product and the gate at the time of opening and closing the parting surface.
