Frequently Asked Questions (FAQ)
QWhat is the output capacity of the CJWS75 twin-screw extruder production line?
The CJWS75 twin-screw extruder production line offers an output capacity of 1โ2 tonnes per hour. It is driven by a 450 kW AC frequency motor with a maximum screw speed of up to 900 RPM, providing both energy efficiency and high throughput for engineering plastics compounding.
QHow does the glass fiber reinforced side feeder protect fiber integrity?
The side feeding design introduces glass fibers into the main material flow in a controlled, sectional manner. This low-shear feeding approach helps preserve fiber length โ particularly long fibers of 6โ25 mm โ reduces fiber damage, prevents agglomeration, and improves dispersion uniformity within the matrix. An efficient high-vacuum degassing system further enhances the final product density.
QWhat materials are used for the barrel and screw elements to ensure durability?
The barrel is fitted with integral tungsten carbide alloy liners, which significantly extend service life and lower maintenance costs. The screw elements are manufactured from powder metallurgy (PM) materials, offering superior wear resistance and mechanical strength for long-term, stable operation under demanding compounding conditions.
QWhich industries are best served by engineering plastics compounding machines?
Engineering plastics compounding machines serve a wide range of industries including automotive (lightweight structural parts), electrical and electronics (precision connectors, insulation components), mechanical engineering (wear-resistant gears and bearings), aerospace (extreme-environment components), medical devices (biocompatible implants), and energy and environmental protection (battery membranes, filter media).
QWhat automation features are included in the production line?
The production line is equipped with a comprehensive automated system including small bag and big bag feeding stations, a quick-opening strand die head, cooling water tank, air knife, gantry pelletizer, lifting conveyor, finished product homogenization silo, and an automatic bagging system โ all designed to maximize production efficiency and minimize manual intervention.
QCan the CJWS75 line be used for emerging applications such as 3D printing or 5G materials?
Yes. The CJWS75 twin-screw extruder is well-suited for compounding advanced engineering plastics used in emerging fields. These include PEEK and PA-based materials for 3D printing of complex structural parts, LCP materials for 5G high-frequency antenna applications, and modified PLA compounds for high-performance degradable engineering plastic applications.
