The concrete steps of the production process of PE pipe are as follows:
1, mixing drying
The effect of mixing drying is to stir, dry and mix the PE resin with the color masterbatch to get the uniform raw material.
2. Plasticizing extrusion
The raw material is pushed from the hopper into the extruder. After transportation, compression, melting and homogenization, the raw material gradually changes from solid pellets to high elastic state, and then from high elastic state to viscous fluid (viscous flow state), and continuously extruded.
3, mold forming
At the appropriate temperature, the material extruded from the extruder enters the mold by the filter plate from the rotating motion to the straight motion. After the screw shunting, the tube shaped billet was compacted and compacted in the forming section, and finally it was extruded from the die.
4, cooling and setting
The heat pipe blank extruded from the die is fixed and cooled by the sizing set and the vacuum sizing box in the negative pressure state, and then the internal cooling of the pipe is gradually cooled through the spray cooling box, so that the whole body is solidified and finalized.
5, cutting
Under the control of the meter wheel, a planetary cutting machine is used to complete the fixed length cutting of the pipe.
6. Stacking and packing
The cut tube was pushed to the overturn table and carried away after inspection and packing.
The above is the concrete steps of the PE pipe in production. When the PE pipe is produced, the above steps are indispensable
