Updated: November 11, 2021 Tools for injection molding may be hard to design or manufacture. However, they have basic concepts which are easy to understand. An injection molding gate system helps to direct the molten plastic from the nozzles of molding machines. This is a gateway of the plastic into the core of the tool.
6 types of injection molding gate & when to use them
The following should help you along the way. Avoid obstructions like pins, cores, and sidewalls that may end up impeding the flow of plastic being injected into the mold. Keep gates away from any form of obstructions. Ensure that the area around the mold gate is well strengthened as it will be subject to a lot of pressure and stress.

Because of this, it is important to know how to use gates before starting an injection molding project. This article looks at six of the most common gate types used in injection molding: edge gates, tab gates, direct/sprue gates, hot tip gates, pin gates, and sub gates. It looks at the properties of these unique gate styles and offers.
Injection Molding Gate Location 5 Tips To Choose The Right Gate Location For Mold
Edge gate, also known as side gate or rectangular gate, is commonly used in injection molding. It receives its name because it typically undergoes processing to shape it into a rectangle. The gate is usually located on the parting surface and feeds from outside the cavity.

Plastic Injection Molding What Is It? How Does It Work?
Gates in plastic injection molding refer to openings through which molten plastic passes to enter the mold cavity. As the name suggest, they serve as gateways - passage - for liquid plastic components to enter the mold cavity. Injection molding gates occur in different forms, taking distinct sizes and shapes - appearing narrow, wide, tapered, etc.
