Industrial 50mm-1.967 Injection Mold Screw Tip Assembly

Description:

The Toshiba Injection Mold Screw Tip Assembly 50 mm (1.967 in.) is used to control molten resin flow, prevent backflow, and ensure consistent shot size during plastic injection molding operations. Commonly installed in Toshiba (Shibaura Machine) injection molding machines with 50 mm injection units, including IS, ISG, and EC series machines used for automotive, medical, packaging, electronics, and consumer product manufacturing. Maintenance technicians, molders, and OEM service providers use this screw tip assembly for replacement of worn check ring assemblies, injection unit rebuilds, preventive maintenance, and restoration of molding accuracy and machine performance. 

Applications:

The Toshiba Injection Mold Screw Tip Assembly 50 mm regulates resin flow during plasticizing and injection while preventing melt backflow during screw recovery. It is widely used for processing polypropylene (PP), polyethylene (PE), ABS, polystyrene (PS), nylon, engineering resins, and glass-filled materials in injection molding facilities producing automotive components, medical devices, packaging products, electrical housings, and consumer goods.
