ZHITIAN Showcases Advanced Twin Screw Extruder Solutions at K 2025: ZT65E Gearbox, ZT818 Tungsten-Cobalt Barrel

The world’s leading plastics and rubber exhibition, K 2025, will take place in Düsseldorf, Germany, from October 8 to 15, 2025. As a global leader in twin screw extruder components, ZHITIAN will showcase its latest technological breakthroughs at Booth No.: 8B D11-15, presenting solutions that redefine performance, durability, and cost-efficiency in extrusion production.

• Specific torque up to 18 Nm/cm³, representing industry-leading standards

• High load-bearing capacity and operational reliability under continuous production

• Precision-ground gears with optimized meshing for reduced noise and extended service life

ZHITIAN’s ZT65E gearbox is designed for demanding extrusion lines where torque density, mechanical efficiency, and durability are critical. It delivers stable power transmission and extended service life, even under continuous high-load conditions.

• Manufactured using Cold Isostatic Pressing (CIP) technology

• Composition: 82% tungsten carbide + 18% cobalt

• Hardness: HRC 68–69

• Impact toughness: ＞13 J/cm²

• Wear resistance: Over 20× higher than conventional HSS 6542

Thanks to its superior wear resistance, ZT818 is regarded as the pinnacle of metal-ceramic materials, offering unmatched durability and long service life in highly abrasive environments.

Applications:

• Lithium battery slurry mixing

• Solid-state battery material processing

• Wood-plastic composite extrusion

• High-filler and abrasive polymer compounding

• Chemical extrusion with corrosive and abrasive additives

ZHITIAN’s laser cladded twin screw extruder barrel is designed to deliver exceptional wear and corrosion resistance through advanced surface engineering. By precisely fusing high-performance alloys onto the barrel’s inner surface, the laser cladding process forms a metallurgically bonded, ultra-hard protective layer that significantly extends service life.

Key Advantages:

• High wear resistance: Ideal for abrasive fillers and high-glass-fiber materials

• Superior corrosion resistance: Suitable for chlorine-containing, acidic, or alkaline additives

• Extended service life: Typically 2–3× longer than nitrided steel barrels

• Cost-effective: Reduces replacement frequency and downtime

This solution is widely used in chemical extrusion, flame-retardant masterbatch production, battery materials, and recycled plastic processing where both wear and chemical resistance are critical.

With more than 20 years of industry experience, ZHITIAN specializes in twin screw extruder parts, including gearboxes, barrels, screw elements, and wear-protection components. Products are exported to Europe, America, and Southeast Asia, trusted by global manufacturers for their high precision, high performance, and superior cost-effectiveness.

Q1: What makes ZT818 different from traditional barrel materials?
A1: ZT818 provides over 20× better wear resistance than standard tool steel (HSS 6542), with excellent toughness and hardness, greatly extending operational life.

Q2: What are the benefits of laser cladding technology?
A2: Laser cladding creates a dense, metallurgically bonded protective layer with superior hardness and corrosion resistance, making it ideal for highly abrasive or chemically aggressive extrusion environments.

Q3: Can ZHITIAN customize twin screw extruder components?
A3: Yes. We offer fully customized barrels, screw elements, and gearboxes based on specific materials, surface treatments, and processing requirements.

Q4: Which industries benefit most from ZT818 and laser cladded barrels?
A4: Industries include battery materials (lithium and solid-state), wood-plastic composites, high-filler compounding, recycled plastics, and chemical extrusion with corrosive or abrasive additives.

Q5: Where can I visit ZHITIAN during K 2025?
A5: Join us at Booth 8B D11-15 at the K 2025 Exhibition in Düsseldorf, Germany (October 8–15, 2025), to see our latest technologies in person.
