【 Lipstick cosmetics packaging hose 】 Injection cosmetics cosmetics packaging hose production mold feed system is made up of which a few parts?

Injection cosmetics cosmetics packaging hose production mold feed system is usually by the sprue, sprue, runner and the cold slug well of four parts.
note: also called feeding port, is the connection pattern in cylinder injection nozzle and injection cosmetics cosmetics packaging hose production mold bridge, is the molten material into the cavity after the first place. Usually sprue is not open on the fixed mold directly but made separate sprue set set on the fixed plate fixed mode. 【 SMC cosmetics cosmetics packaging hose production mold 】
port: since the sprue to the gate in order to extend, also known as the mainstream, distributary channel, its effect is under the condition of minimum pressure loss, to transfer the molten material from the sprue to the gate, so into the cavity.
gate: is the part of connection port and cavity, and at the end of the feed system, the demand for it is to make the flow of molten material quickly through the gate with cavity, at the same time in the cavity is filled with material gate after rapid cooling to prevent high pressure hot material return within the cavity.
cold slug well: general Settings in the end of the parting surface, or end in the port. Its role is JiCun cold to prevent cold material blocking port or enter a cavity lesion or cold stamping on the spot. The causes of slag is the forefront nozzle molten material temperature is low.
the place on put together is narrated, injection cosmetics cosmetics packaging hose production mold feed system, is to make quickly filled with molten material are all from the injection nozzle cavity, and pressure transmission in molding process to various parts of the cavity to make uniform molding parts.
