ZSE87 ZSE110 60° Kneading Block For Co-Rotating Twin Screw Extruder Screw Element

ZSE87/ZSE110 60° Kneading Block For Co-Rotating Twin Screw Extruder Screw Element

ZSE87 60° kneading block and ZSE110 60° kneading block serve as core mixing components for ZSE87 MAXX and ZSE110 MAXX co-rotating twin screw extruders. Firstly, the 60° offset disc structure delivers balanced shear force and stable material conveying capacity. Secondly, it provides stronger dispersive mixing effect than 30° and 45° kneading blocks. For this reason, extrusion factories widely install this screw element in melting zones and main mixing zones of twin screw compounder screw layouts.

We adopt professional 5-axis CNC machining to produce every kneading block. Strict production standards control dimensional tolerance within ±0.02mm. Meanwhile, the standard involute spline bore matches original spline shafts perfectly. This precise structure eliminates assembly gaps and avoids vibration during high-torque continuous operation. Furthermore, we support diversified material selection and surface treatment to adapt to different extrusion working conditions. Besides standard specifications, we also provide customized size services to meet personalized screw configuration demands.

• Precise Machining & Stable Operation
  We apply 5-axis CNC integral machining for all kneading blocks. Tight tolerance control ensures zero shaking and stable high-speed operation. Thus, it effectively reduces equipment failure rate and improves overall extrusion production efficiency.
• Diverse Material Matching for All Working Conditions
  We equip multiple high-performance materials for different production scenarios. Conventional nitrided steel fits general plastic compounding. In contrast, WR5 and SAM series alloy materials adapt to high-abrasion working conditions with massive mineral fillers and glass fiber additives.
• Three Rotation Modes for Flexible Process Adjustment
  Forward, neutral and reverse three structural types cover all polymer processing needs. Forward blocks accelerate material conveying and regular mixing. Reverse blocks build reasonable backpressure to enhance material homogenization. Neutral blocks provide moderate shear force for delicate material processing.
• Perfect Compatibility & Easy Installation
  Standard involute spline design fully matches original ZSE series equipment. Customers can directly replace old and worn parts without secondary processing or modification. This design greatly saves installation time and maintenance cost.
• Superb Wear & Corrosion Resistance
  Optional gas nitriding and alloy spray welding surface treatments strengthen surface hardness and abrasion resistance. Therefore, the kneading block extends service life obviously and reduces long-term spare part replacement costs.
• Professional Customization & OEM Support
  We accept personalized customization according to customer drawings or sample sizes. Our professional technical team verifies parameters strictly to produce exclusive screw elements that fit your screw layout perfectly.

This ZSE87 and ZSE110 60° kneading block applies to all kinds of polymer extrusion and compounding industries. First, it suits glass fiber reinforced PP and PA engineering plastic modification. Second, it supports color masterbatch and functional masterbatch production with high mineral filling. Third, it completes polymer alloy blending and homogenization processing. Fourth, it works for biodegradable PLA and PBAT plastic compounding. In addition, it adapts to cable material, thermoplastic elastomer and recycled plastic extrusion production.

1. Q1: Why choose 60° kneading block instead of 30° and 45° types?
   60° kneading block provides stronger shear force and better dispersive mixing performance. It delivers more thorough material homogenization effect. So it is the best choice for high-filler modification, fiber reinforcement and high-uniformity compounding processes. You can choose smaller angle types if you prioritize fast material conveying.
2. Q2: Do you supply forward, neutral and reverse ZSE87/ZSE110 60° kneading blocks?
   Yes, we fully support all three rotation types. You only need to confirm the required type and screw layout parameters in your inquiry to get matching products.
3. Q3: What material is best for high-abrasion masterbatch production?
   We recommend WR5 or SAM10 alloy kneading blocks with alloy spray welding treatment. These materials resist strong abrasion from calcium carbonate, talcum powder and glass fiber fillers, and they maintain long-term stable working performance.
4. Q4: Can you produce non-standard custom kneading blocks?
   Absolutely. We provide one-stop OEM customization services. You can send us your design drawings or original sample dimensions, and we will complete parameter verification and customized production.
5. Q5: What is your production lead time?
   Standard in-stock kneading blocks can be delivered within 7 working days. Meanwhile, customized non-standard products take 15 to 20 working days. We will confirm the exact delivery time in the formal quotation.
6. Q6: Is this kneading block compatible with old ZSE series extruders?
   Our products follow ZSE MAXX series original standards. For old-generation equipment, you can provide spline and dimension parameters, and our team will confirm compatibility for you for free.

Please tell us your required rotation type, material grade, total length and disc quantity of ZSE87 or ZSE110 60° kneading block. You can also attach your screw layout drawing. We check all specifications strictly and provide competitive factory quotations within 24 hours.
