MAIN MACHINE LIST

1.Extruder

Based on 33:1 L/D ratio for screw design, we have developed 38:1 L/D ratio. Compared with 33:1
ratio,38:1 ratio hasadvantage of 100% plasticization, increase output capacity by 30%, reduce power consumption
up to 30% and reach almost linear extrusion performance.

2.Die head

Die head apply spiral structure, each material flow channel is placed evenly. Each channel
is after heat treatment and mirror polishing to ensure material flow smoothly. Die head structure is compact and
also provide stable pressure, always from 19 to 20Mpa. Under this pressure, pipe quality is good and very little
effect on the output capacity. Can produce single layer or multi-layer pipe.

3.Vacuum tank

Vacuum tank is used to shape and cool pipe, so as to reach standard pipe size. We use double-chamber
structure.First chamber is in short length, to ensure very strong cooling and vacuum function. As calibrator is
placed in the front of first chamber and pipe shape is formed mainly by calibrator, this design can ensure quick
and better forming and cooling of pipe.

4.Cooling tank

Water cooling tank is used to cool pipe further.

5.Haul off machine

Haul off machine provides sufficient traction force to pull pipe stably. According to different pipe sizes and
thickness, our company will customize traction speed, number of claws, effective traction length. To ensure
match pipe extrusion speed and forming speed, also avoid deformation of pipe during traction

6.Cutting machine

Cutting machine controlled by Siemens PLC, working together with haul off unit to have precise cutting.Customer
can set the length of pipe they want to cut. Multi-feed-in actions for the accomplishment of one cutting process
(protect blades and saws, prevent from blade and saws stuck for thick pipe and cut face of pipe is smooth).

7.Stack rack

To support and unload pipes. Length of stacker can be customized
