The special nozzles of injection molding machines are divided into three categories: shut-off series, filter & mixing series, and silicone series.
1. Shut off nozzle:
2. Filter & mixing nozzle:
3. L.S.R specialized shut off nozzle
Internal spring controlled shut-off nozzles of injection molding machines mainly serve the leakage of low density thermo-plastic injection processes, like PA, PP, PS, and PE, which can improve production efficiency and save production cost, and it’s used a lot in the low-frequency injection process.
The needle shut-off nozzle can be optionally driven by pneumatic or hydraulic drive. It’s often used to prevent material leakage and wire-drawing of plastic. It can also be applied in synchronization dosing situations and in the micro-foaming(physical or chemical) injection field.
Piston valve shut-off nozzles of injection molding machines are commonly used to shorten cycle time by synchronizing screw dosing during mold opening, and to prevent material leakage, the unique sealing design offers a single pass channel with fewer pressure loads and max. shot weight, and also guaranteed excellence in product color changing.
The injection molding machine filter nozzle is mainly used to purify passing polymer, block foreign objects from entering the mold, and improve production quality & surface appearance. By adding a block or barrier section inside the nozzle, it can be customized per actual application and block foreign objects inside the nozzle.
The benefit of static mixer color mixing nozzle:
LSR specialized shut-off nozzle is designed for liquid silicon rubber injection process, which is integrated inside pneumatic and water circuit system to prevent the vulcanization and leakage of L.S.R.
Application field:
Mainly used on baby and infant products, medical products, electronic components, phone cases, and wearable devices.
