The production process design of pipe extrusion forming

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”.

The main process parameters of pipe extrusion forming, which are refer to the molding temperature, pressure, extrusion rate, and traction speed.

The key points of production process design for pipe extrusion forming are: under the premise that the raw materials and equipment have been determined, the selection and control of process conditions during the production process (i.e. production process design) is particularly important. Therefore, it is necessary to develop production process conditions that are both theoretical and practical.

The process design mainly focuses on the following aspects:

(1) Temperature control,

(2) Cooling control,

(3) Cooling speed,

(4) Calibrating method,

(5) Traction speed.

Due to different production materials, the process conditions to be considered are also different, but they are generally reflected in the above five aspects.
