Product Detail

LINA Kneader-Screw Discharge & Forming Integrated Machine

One-step mixing–conveying–forming for high-viscoelastic materials

1. Product Positioning
Leveraging 30 years of kneader / internal mixer expertise and single-screw extrusion technology, LINA launches an all-in-one unit that integrates “kneader + screw discharge + forming die”. Within one sealed chamber it completes high-viscosity material kneading, devolatilization, steady-pressure conveying and continuous forming, eliminating the pain points of “multiple machines, repeated transfers, contamination and high loss”.
2. Core Structure & Workflow
  1. Top — Vertical Kneader
    • Double “Σ” or Z blades, high-torque hardened reducer, 5–40 rpm VFD
    • All wetted parts SUS304/SUS316L mirror-polished
    • Jacket/half-pipe heating, PID ±2 °C accuracy
    • Vacuum/nitrogen ports for degassing & drying
  2. Middle — Hydraulic Gate + Forced Feeding
    After kneading, the hydraulic gate opens instantly; blades rotate slowly to push material into twin-screw forced-feeding section, eliminating bridging and back-flow.
  3. Bottom — Single-Screw Extrusion & Forming
    • Φ45–150 mm barrier screw, alloy steel + nitrided/bimetallic sleeve
    • Multi-zone barrel temp, gear pump for stable pressure (±1 %)
    • Quick-change die: rods, sheets, profiles, films
    • Optional hot-cut air cooling, water strand, calender or lamination line
  4. Overall Control
    Siemens PLC + 10″ HMI, 100 recipes; full-line linkage, one-button start/stop, 4G remote module option.
