Submarine Gate Injection Molding

1 injection molding gate is a small opening between the runners and the mold cavity.

Submarine gate injection molding. Tunnel or submarine 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. If unavoidable the weld marks should be designed on the unimportant surface and non weak parts of the product. 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.

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. Their location quantity shape and size etc. 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.

2 the gate size is dependent on product weight material and gate types. If the injection molding requirements meet the smaller the number of gates are the better it is it would reduce the weld marks. Plastic injection molding is a complex highly intricate process. The gate is where the molten plastic flows into the final part.

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. Every type of gate that has its advantages today we will explain each type of molding gate when you use your molding parts according to each gate of advantages and disadvantages you could. With submarine gates the part is broken from the. Have a great influence on product appearance dimensional physical characteristics and production efficiency.
