Jun 21, 2024 · Direct or sprue gates are the simplest and most traditional type of gates. They have a slight taper and circular cross-section and are typically located at the part’s thickest section, directly connected to the runner system.

Jan 6, 2023 · The direct/sprue gate type is simple and common in injection molding. The sprue moves and melts directly into the mold cavity allowing the quick injection of large plastic volumes. It usually requires less injection pressure and a short feeding time.

Feb 24, 2021 · Direct gates are easy to implement but produce high tensile stress around the gate. Direct gates are suitable for: Single-cavity molds; Non-aesthetic parts; Automatic trim gates. These three gate types are designed to be removed automatically by the injection molding machine as it ejects the finished part from the mold. Hot tip gate

Nov 25, 2024 · The direct sprue gate is a basic and conventional type of injection molding gate. It has a slight taper and circular cross-section. Its connection with the molded part is at the biggest cross-section.

A direct gate is one of the simplest gate types used in injection molding. It uses a hot runner system, where the gate is left open, gating into a pinpointed area – this allows molten plastic to flow directly from the runner into the center of the part.

Direct gate injection molding, also known as sprue gating, involves injecting molten material directly into the mold cavity through a single gate. This straightforward gating method is suitable for simple part geometries and can help streamline the molding process.

Jul 10, 2023 · In injection molding, a direct sprue gate is the most common type of gate design used to introduce molten plastic into the mold cavity. The sprue gate is located directly at the parting line of the mold, typically at the thickest section of the plastic part.

Direct or Sprue Gate. A manually trimmed gate, a direct or sprue gate is used to produce symmetrical filling of single cavity molds for large cylindrical parts. A direct gate can almost be thought of as the absence of a gate: the sprue carries material directly into the mold cavity.

Direct or sprue gates are the most common type of gate used in injection molding. They are typically used for large parts or parts that require a high volume of material. In this type of gate, the molten plastic is injected directly into the center …

Direct sprue gates are well-suited for boxed or shell moulds with a single deep cavity and for producing non-aesthetic parts, making them ideal for manufacturing consumer products and home appliances. Key features of direct sprue gates. Large opening, gradual widening; Placed at edge; Suitable for large surfaces and complex geometries
