Submarine Gate Injection Molding

2 the gate size is dependent on product weight material and gate types.

Submarine gate injection molding.

The gate is where the molten plastic flows into the final part. A type of edge gate where the opening from the runner into the mold is located below the parting line or mold surface. Plastic injection molding is a complex highly intricate process. 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.

It serves as the boundary between the part and the scrap the injection molding gate type include director gate sub gate fan gate side gate bananal gate tab gate etc. The gate architecture and its location affects cycle times tooling costs lead times the location of witness marks and many other potential defects that are commonplace for injection molded parts. If the injection molding requirements meet the smaller the number of gates are the better it is it would reduce the weld marks. Our glossary of terms provides definitions for a wide range of injection molding terms.

Horn submarin gate applies to product surface free of any traces of the gate also submarine gate isn t feasible select the horn submarin gate gate can be set inside of the article and the surface of the injection molded article can be significantly improved as to aesthetic effect it is made inserts for its special shape. If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of the product. Tunnel or submarine gate. Have a great influence on product appearance dimensional physical characteristics and production efficiency.

One of the reasons it s the best is because a tunnel gate automatically separates or degates from the part when either the mold opens or when the parts and runner are ejected. The runner and gate system used in plastic injection molding is responsible for directing molten plastic from the nozzle of the molding machine into the cavity of the tool. With submarine gates the part is broken from the. There are many types of gates for plastic injection molding parts such as direct sprue gate side gate fan gate pinpoint gate submarine gate etc.
