Ningbo Tianze Machinery Technology Co., more infor pls find sales(at)tizatech.com
We machine, hard-surface,grind and polish to precision tolerances in injection screws manufacturing. Special hard-surfacing alloys are made with Nickel, Tungsten-Carbide and Molybdenum.
In injection molding machines, the plasticizing unit: the screw and cylinder turns solid resin into uniform melt. In the plasticizing process, the most important elements include selecting materials suitable for various plastic resins, mechanical design, and injection molding parameters (melt temperature, metering, speedtime, back pressure, holding pressure, etc.).
Components of Plasticizing Unit:
Barrels, Screws, Screw Tip Valves, Screw Tip Assemblies, Check Ring, Rear Seat, End of Barrel, Barrel End Cap Adapters, Nozzle Bodies and Nozzle Tips, Nozzles
Screw Design:
Screw design must focus on mixing, pumping, melting and conveying tasks. Injection screws must be designed in accordance with the properties of the polymer to realize the best-level kneading and plasticizing performance. Application specific elements that affect output include:
• Screw total length • Feed zone • Transition zone • Metering zone • Channel depth
• Helix angle • Flight clearance • Flight width • Pitch/Lead (spacing) • Screw O.D. /Barrel size
• Nozzle & tip design• Flight length • Material to be processed• Volumetric feeding • Continuous feeding
• Steel and Finishes• Wear and durability• Temperatures control
We meet and exceed our customers expectations by offering:
Carefully engineered screw geometry to match the exact needs of your process.
Reduced cycle times and longer machine life.
Pairing of base materials and surface treatments to maximize screw life.
Screw recovery solutions for high performance and multiple applications.
Quality inspections with every step of the process to create customized parts specific to our customers demands.
