The K 2025 – International Trade Fair for Plastics and Rubber will take place from October 8–15, 2025, in Düsseldorf, Germany. As a trusted innovator in twin screw extruder spare parts manufacturing, Zhitian will present its latest technologies and material solutions at Booth 8B D11-15, highlighting advancements in gearbox systems, barrel materials, and wear-resistant solutions for high-performance extrusion.
ZT65E High-Torque Gearbox
Designed for co-rotating twin screw extruders, the ZT65E delivers a torque density of 18 Nm/cm³, representing industry-leading performance. This gearbox combines maximum efficiency with long service life, making it a reliable choice for demanding compounding and extrusion applications.
Laser-Cladded Tungsten Carbide Barrels
Zhitian’s advanced laser cladding technology enhances barrel inner surfaces with a nickel-based tungsten carbide coating, offering exceptional anti-wear and anti-corrosion resistance. This innovation significantly extends the service lifespan of extruder barrels while reducing maintenance frequency.
ZT818 Cobalt-Based Tungsten Carbide Sleeves
Produced through Cold Isostatic Pressing (CIP) with 82% tungsten carbide and 18% cobalt, ZT818 achieves a hardness of HRC 68–69 and impact toughness above 13 J/cm². Independent tests show that its wear resistance is over 20 times greater than conventional 6542 tool steel. Applications include WPC extrusion, high-filler plastics, rubber processing, lithium battery materials, and solid-state battery production, where both durability and contamination control are critical.
| Material | Before Test (g) | After Test (g) | Weight Loss (g) | Relative Performance |
|---|---|---|---|---|
| 6542 Tool Steel | 63.5517 | 63.4817 | 0.0700 | Baseline |
| ZT818 Co–WC | 74.3217 | 74.3181 | 0.0036 | 20× More Wear Resistant |
For over two decades, Zhitian has specialized in twin screw extruder gearboxes, barrels, screw elements, and shafts, with products exported to Europe, the Americas, and Southeast Asia. By combining high-precision machining, advanced alloy technology, and customized solutions, Zhitian continues to help customers improve extrusion performance while reducing downtime.
Q1: What makes ZT818 different from traditional barrel sleeve materials?
A1: ZT818 offers 20 times the wear resistance of standard tool steel, combining high hardness with superior toughness, making it ideal for extreme wear applications.
Q2: Which industries will benefit most from Zhitian’s solutions?
A2: Sectors such as plastics compounding, WPC extrusion, battery materials, and chemical processing benefit significantly due to the demand for both durability and process stability.
Q3: What advantages does laser cladding bring to extruder barrels?
A3: Laser cladding creates a dense, metallurgical bond on the barrel inner wall, providing longer service life, lower maintenance costs, and enhanced corrosion protection.
