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

The barrel is equipped with integral tungsten carbide alloy liners, extending service life and reducing maintenance costs.

🔩 High-Performance Screw Elements

Screw elements made of powder metallurgy (PM), featuring high wear resistance and mechanical strength to ensure 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 delivers an output capacity of 1–2 tonnes per hour, powered by a 450 kW AC frequency motor with a maximum screw speed of up to 900 RPM, making it suitable for high-efficiency engineering plastics compounding production.

❓ How does the glass fiber reinforced side feeder protect fiber length?

The side feeder uses a low-shear feeding mechanism that introduces glass fibers into the main material flow in a controlled, sectional manner. This approach preserves fiber length — particularly long fibers of 6–25 mm — minimizes fiber damage, prevents agglomeration, and improves dispersion uniformity within the matrix material.

❓ What materials are used in the barrel and screw elements to ensure durability?

The barrel is equipped with integral tungsten carbide alloy liners for extended service life and reduced maintenance costs. The screw elements are manufactured using powder metallurgy (PM), providing high wear resistance and mechanical strength for long-term stable operation under demanding processing conditions.

❓ Which engineering plastics are commonly used in the automotive industry?

Key engineering plastics for automotive applications include Nylon (PA) for fuel lines and intake manifolds, Polycarbonate (PC) for headlight covers and instrument panels, Polyoxymethylene (POM) for door locks and seat belt components, and Polyphenylene Sulfide (PPS) for high-temperature sensor housings and ignition components. These materials contribute to vehicle lightweighting and improved fuel efficiency.

❓ Is PEEK material suitable for medical device applications?

Yes. Polyetheretherketone (PEEK) is widely used in medical devices due to its excellent biocompatibility and ability to withstand sterilization processes. It is commonly applied in orthopedic implants and dental instruments as a reliable metal alternative, offering high strength, chemical resistance, and long-term stability in biological environments.
