Product Details

Performance & Features by Line Configuration

CJWS75 Twin-Screw Extruder

Main Extruder Model: CJWS75

⚡ Motor Power

450 kW (AC frequency motor), maximum screw speed up to 900 RPM, energy-saving and high efficiency.

📦 Output Capacity

1–2 T/h

⚖️ Loss-in-Weight Feeding System

Automatic high-precision metering and feeding for multiple materials, ensuring accurate formulation control.

🎯 High-Precision Metering

Automatic material weighing to ensure consistent and stable product quality.

🛡️ Durable Barrel

Equipped with integral tungsten carbide alloy liners, extending service life and reducing maintenance costs.

🔩 High-Performance Screw Elements

Made of powder metallurgy (PM), featuring high wear resistance and mechanical strength for long-term stable operation.

🌿 Glass Fiber Reinforced Side Feeder

The side feeding design allows glass fibers to be introduced into the main material flow in a controlled and sectional manner, preventing fiber agglomeration and improving dispersion uniformity in the matrix. Low-shear feeding helps preserve fiber length (especially long fibers of 6–25 mm), reduces fiber damage, and enhances final product density through efficient high-vacuum degassing. The buffer hopper is equipped with an agitator to prevent material bridging and improve feeding efficiency.

🤖 Automated Production System

Equipped with small bag and big bag feeding stations, quick-opening strand die head, cooling water tank, air knife, gantry pelletizer, lifting conveyor, finished product homogenization silo, and automatic bagging system to improve overall production efficiency.

Frequently Asked Questions (FAQ)

What is the output capacity of the CJWS75 Twin-Screw Extruder?

The CJWS75 Twin-Screw Extruder has an output capacity of 1–2 T/h, driven by a 450 kW AC frequency motor with a maximum screw speed of up to 900 RPM, making it highly energy-efficient and suitable for large-scale production.

How does the glass fiber reinforced side feeder preserve fiber length?

The side feeding design uses a low-shear feeding mechanism that introduces glass fibers into the main material flow in a controlled, sectional manner. This approach minimizes fiber damage and helps preserve fiber lengths, especially long fibers of 6–25 mm, while improving dispersion uniformity in the matrix.

What materials are the screw elements made of, and why does it matter?

The screw elements are manufactured using powder metallurgy (PM), which provides exceptional wear resistance and mechanical strength. This ensures long-term stable operation even when processing highly abrasive or filled materials, significantly reducing downtime and maintenance costs.

Which industries can benefit from engineering plastics compounding machines?

Engineering plastics compounding machines serve a wide range of industries including automotive, electrical and electronics, mechanical manufacturing, aerospace, medical devices, energy and environmental protection, as well as emerging sectors such as 3D printing and 5G communication.
