Temperature control in the production process of PVC pipe & fittings!


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”.


In the production process of PVC pipes and fittings, temperature control is very important, which directly affects the later quality of the product and has a great impact on the use of the product. The following we will give you a brief introduction.


The processing performance of PVC material is relatively narrow and its thermal stability is poor, so its processing temperature range is relatively narrow and its adaptability to machines and molds is poor. Generally, PVC pipes can be set between 160 - 210 . The specific temperature still needs to be determined according to different extrusion equipment, molds and different specifications. Because the models and structures of different machines are different, there is a large gap in its plasticizing capacity. Therefore, the processing temperature of pipes with the same specification and formula on different machines can differ by 10 - 40 . Generally, the processing temperature of PVC pipe is suitable for the smooth appearance and moderate strength of pipe blank when melting the pipe blank export mold.
