High Efficiency and Automation + High Quality and Stable Production! Technology and Application of Engineering Plastics Modification and Granulation Equipment

Engineering plastic compounding refers to the technology of optimizing the performance of engineering plastics (such as PA, PC, PBT, PPO, PPS, etc.) to meet specific application requirements through physical, chemical or a combination of both methods. The core goal of modification is to improve the mechanical strength, heat resistance, chemical resistance, flame retardancy, wear resistance, etc. of the material, or to reduce costs and improve processing performance. It is mainly used in the automotive industry, electrical and electronic industry, machinery industry, aerospace, medical equipment, energy and environmental protection, etc.

Introduction

Model：CJWS75

Power：450KW (AC frequency motor), maximum screw speed 900RPM, energy-saving and efficient.

Output：1T-2T/h

Loss-in-weight ：Automatic metering and feeding of multiple materials with high precision to ensure formula accuracy.

High-precision metering：Automatic material measurement to ensure the stability of product quality.

Durable barrel：The barrel adopts  tungsten carbide alloy liners to extend the service life of the barrel and reduce maintenance costs.

High-performance Screw Elements：made of PM, with high wear resistance and strength to ensure long-term stable operation.

Glass fiber reinforced side feeder：The side feeding design allows the glass fiber to enter the main material flow in sections and in a controllable manner from the side, avoiding fiber concentration and agglomeration, improving the dispersion uniformity in the matrix material, reducing fiber damage, and achieving high vacuum exhaust effect, thereby improving the density of the final product. Low shear feeding can better maintain the fiber length (especially long fiber reinforcement, such as 6~25mm), and the buffer hopper is stirred to prevent the material from bridging in the hopper, thereby improving the feeding efficiency.

Automated production：Equipped with small bag and ton bag feeding stations, quick-opening strand die head, cooling water tank, Air knife,Gantry pelletizer,Lifting conveyor, Finished product homogenization silo and Bagging system to improve production efficiency.
