The plastic pipe extrusion line (PEL) is used for manufacturing plastic pipe.

 In order to provide customers excellent PEL system, the PEL has been improved effectively by technicians during the last 10 years. 

This innovation can be summarized through the following aspects, namely the module layout or operation mode, the cooling system, the productivity, the operation stability, the flexibility of products, and the lower of power consumption. Generally, three time marks can be noted in the development history as three generations, which happened in 2001, in 2006, and in 2009, respectively. Based on the cooling system, three types of PEL with various production speeds can be classified.
