Description
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
- 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 - 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. - 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 - Overall Control
Siemens PLC + 10″ HMI, 100 recipes; full-line linkage, one-button start/stop, 4G remote module option.
