1.Production capacity: The daily capacity of Tongda’ four-pipe extrusion line is above 12 tons.
2.Water and air consumption: Tongda’ optimized cooling water channel and air circuit make the water and air consumption is 25% of the one of the traditional one.
3.The noise pollution: The saw blade of the traditional cutting equipment makes piercing noise while Tongda’ chipless cutting make no noise.
4.Dust pollution: The traditional saw cutting causes severe dust pollution and the materi···

Based on 39 years of plastic extrusion machinery development and design experience, Tongda combined the advanced technology to prompt this HDPE water and gas pipeextrusion line. Its unique structure design and high efficiency performance makes it fast accepted by the pipe factories.

PVC pipe production line is mainly used to produce PVC pipes with all kinds of Diameter & thickness that are used for water supply and drainage as well as cable laying. This machine is made up of conical twin screw extruder, vacuum tank, HAUL-OFF machine, stacker etc.. The extruder and HAUL-OFF machine are controlled by imported AC variable frequency device. The vacuum pump and the motor of the HAUL-OFF machine are both of high quality.
