High-End Twin Screw Extruder Parts Manufacturer

As global demand grows for higher performance and greater efficiency in polymer processing and compounding industries, the need for advanced twin screw extruder parts has never been more critical. Zhitian, founded in 2006, is a trusted manufacturer specializing in high-end twin screw extruder parts, including gearboxes, barrels, and custom alloy solutions. With two production facilities in Nanjing and Anhui, Zhitian serves customers worldwide with precision-engineered components and cost-effective material innovations.

Why Choose Zhitian as Your Twin Screw Extruder Parts Supplier?

Zhitian not only manufactures precision components for twin screw extruders but also develops tailor-made alloy technologies to address the toughest operational challenges. Here's how we solve the most pressing problems in the extrusion industry:

1. Problem: Extreme Wear and Corrosion in Harsh Operating Conditions

In complex working environments where abrasion and chemical attack are severe, traditional materials like tool steel or nitrided alloys often fall short.

Zhitian's Solution:
Our ZT818 cobalt-based tungsten carbide alloy liner was developed through cold isostatic pressing (CIP) technology. Laboratory tests have shown that its wear resistance is over 20 times higher than HSS 6542. This alloy provides a reliable and balanced performance in wear resistance, corrosion resistance, and structural strength, making it ideal for extreme-duty barrel applications.

2. Problem: High-Performance Alloys Are Too Expensive for Large Extrusion Systems

While powder metallurgy materials offer excellent performance, their cost can be prohibitive, especially for large twin screw systems (Φ65mm and above).

Zhitian's Solution:
We offer a cost-efficient alternative by applying a 1–2 mm thick nickel-based tungsten carbide alloy layer through laser cladding on the barrel inner surface. This method not only improves wear and corrosion resistance, but also reduces machining time and overall material cost. The metallurgical bond ensures long-term stability, and the larger the machine size, the more obvious the cost advantage.

3. Problem: Rising Energy Costs and Demand for Higher Output Efficiency

Energy consumption and floor space are major concerns in modern extrusion plants.

Zhitian's Solution:
Our ZT-E series twin screw extruder gearboxes are engineered with a torque density of 18 Nm/cm³, significantly boosting single-machine output capacity. This allows producers to maintain or increase production using fewer machines, smaller motors, and less energy, while also reducing footprint and maintenance costs. It’s a smart choice for sustainable and cost-effective production.
