Product Description
Threaded Element Threaded Block Kneading Block | Twin Screw Plastic Granulator Meshing Accessories
Threaded Element Threaded Block Kneading Block – Full Series Meshing Accessories For Twin Screw Plastic Granulator
Product Overview
Threaded element, threaded conveying block and meshing kneading block are the core modular spare parts for co-rotating twin screw plastic granulators, covering the full extrusion process of feeding, conveying, melting, homogenization mixing and pressure building.
Threaded Element / Threaded Block: Mainly responsible for material conveying, forward pushing and pressure adjustment; available in wide pitch, medium pitch and narrow pitch to control throughput, residence time and melt pressure.
Meshing Kneading Block: Multi-lobe staggered meshing structure, provide dispersive and distributive mixing, break up fillers, evenly blend plastic matrix, fiber, powder and additives.
All twin screw plastic granulator meshing accessories adopt WR5 powder metallurgy alloy, 6542 high-speed steel or nickel alloy blank, processed by 5-axis full CNC precision grinding, integral vacuum quenching to stable HRC58–62 hardness. Standard involute spline inner hole ensures zero-clearance assembly with extruder spline shaft, precise self-wiping profile eliminates material dead zone and carbonization. Widely matched with TEX, STS, ZSE series twin screw granulators for color masterbatch, WPC composite, glass fiber reinforced engineering plastic, biodegradable plastic and waste plastic recycling pelletizing production lines.

Functional Difference & Core Advantages
Threaded Element & Threaded Conveying Block (Conveying Section Parts)
- Adjustable pitch design realizes flexible throughput control: wide pitch for high feeding capacity, narrow pitch for material compression and melt pressure build-up.
- Smooth spiral surface reduces flow resistance, lower extruder power consumption, improve granulator production efficiency.
- High hardness alloy base resists abrasion from calcium carbonate, talc and mineral powder, long service life for high-filler production.
- Self-wiping spiral profile avoids material residue, easy formula switching without frequent shutdown cleaning.
Meshing Kneading Block (Mixing Homogenization Parts)
- Multi-angle staggered meshing lobes provide balanced shear force, fully disperse pigment, glass fiber and inorganic fillers to ensure uniform pellet color and stable mechanical performance.
- Optional low-shear single-end chamfer kneading block prevents heat-sensitive PLA/PBAT plastic degradation and black speck defects.
- Precise meshing gap eliminates material stagnation dead zone, avoid local overheating carbonization during continuous pelletizing.
- Modular combination freely collocate with threaded blocks to design customized screw configuration according to different plastic formulas.
Universal Advantages of All Series Meshing Accessories
- Uniform HRC58-62 high hardness, excellent wear & corrosion resistance, greatly reduce replacement frequency and production downtime.
- 5-axis CNC precision machining ensures consistent dimensional tolerance, stable operation without abnormal vibration and noise.
- Complete matching with twin screw spline shaft and alloy barrel, plug-and-play replacement without equipment modification.
- Two surface treatment options: mirror polishing for easy cleaning; sandblasting matte finish to prevent viscous melt adhesion.

FAQ
Q1: What is the function of threaded element and kneading block in twin screw plastic granulator?
A: Threaded element/threaded block are responsible for material conveying and pressure adjustment; meshing kneading block provides shear mixing to disperse fillers, pigments and additives for uniform plastic pellet performance.
Q2: What is the hardness of your twin screw threaded and kneading meshing block?
A: All alloy threaded elements and kneading blocks are vacuum heat treated to stable uniform HRC58–62 hardness for long-term wear-resistant granulation production.
Q3: What is the difference between wide pitch and narrow pitch threaded block?
A: Wide pitch threaded block offers larger throughput for high-output feeding; narrow pitch threaded block compresses materials to build melt pressure, suitable for melting and exhaust sections.
Q4: Can kneading block handle long fiberglass reinforced plastic?
A: Yes, we supply low-shear single-end chamfer meshing kneading block, which reduces fiber breakage and retains fiber length to guarantee finished plastic tensile strength.
Q5: Are these threaded and kneading parts compatible with JSW TEX twin screw granulator?
A: 100% OEM interchangeable. All outer diameter, center distance and spline parameters strictly follow TEX/STS original equipment standards for direct replacement.
