Advanced Extrusion Process Control

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

Modern pipe extrusion machines are equipped with advanced process control systems that ensure optimal performance and product quality. These systems monitor and control various parameters throughout the extrusion process, including temperature, pressure, and material flow. Key components of advanced process control include:

1. Temperature Control

Precise temperature control is critical in pipe extrusion to ensure proper melting and homogenization of the plastic material. Advanced machines use multiple heating zones with independent control to maintain consistent temperatures along the extruder barrel. This ensures uniform melting and reduces the risk of material degradation.

2. Pressure Monitoring

Pressure monitoring systems track the pressure within the extruder and die, ensuring consistent material flow and preventing potential issues such as die swell or melt fracture. These systems provide real-time feedback to the operator, allowing for quick adjustments to maintain optimal extrusion conditions.

3. Material Feeding and Dosing

Accurate material feeding and dosing are essential for consistent product quality. Modern extrusion machines use gravimetric or volumetric feeders to precisely control the amount of material entering the extruder. This ensures a consistent melt flow and reduces the risk of variations in pipe dimensions.

4. Screw and Barrel Design

The design of the screw and barrel significantly impacts the performance of the extrusion process. Advanced machines use specialized screw designs optimized for specific materials and applications. These designs enhance mixing, homogenization, and material conveyance, resulting in higher output rates and better product quality.
