Molding Guidelines Gate Design The gate serves as the entrance to the cavity and should be designed to permit the mold to fill easily. A cavity can have more than one gate.
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.

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.
