PP Hollow Board Extrusion Line

GWELL, as China Plastic Extruder Supplier, PP Hollow Board Extrusion Line adopts PP hollow special single-screw extruder and double extruder for co-extrusion. Because PP hollow board is divided into white and black PP hollow board. Sometimes the middle of the board will be white. So China GWELL will use two extruders.

Features of PP Hollow Board Extrusion Line

 

  1. The unique design of the mold, setting plate, cooling system and vacuum system ensures high-speed extrusion molding, good wear resistance, good shapeability, and easier operation.
  2. Through the design of the two-stage combined tractor, the flatness of the product can be effectively controlled, and the unqualified products produced by each startup can be reduced.
  3. The special cutting design can reduce the burrs on the end face of the product to a certain extent. For the improved sawtooth of PP raw materials, the sawdust will not stick during cutting. The automatic fixed-length function of the product is convenient for personnel to operate and has high cutting accuracy.
  4. China GWELL as a supplier of extruders The whole line adopts new process technology, the production line speed is fast, and the extruder adopts energy-saving and high-efficiency extruder, which has high extrusion volume, good plasticization and stable conveying.

 

Hollow board features

 

  • Light weight, anti-stretch and other properties.
  • The surface can be printed or pasted with lamination.
  • Different colors can be produced according to demand.
  • By adding flame retardant, the produced hollow board can be extinguished immediately after fire.
  • PP hollow board extrusion line has high efficiency.
  • Production flexibility (the thickness and width of the plate can be controlled, for example, the same mold or machine can be used to produce 2-6mm thick plates)
  • PP hollow board extrusion line reliability and stability.
  • Strong adaptability to different raw materials, and the production cost is reduced by more than 30%.

GWELL PP hollow board extrusion line Feature

1. Extruder

As a China Plastic Extruder manufacturer, Gwell uses a PP hollow special single-screw extruder, and uses a twin-extruder for co-extrusion. Because the PP hollow board is divided into white and black PP hollow board extrusion lines, sometimes white appears in the middle of the board. So China Gwell will use two extruders.

2. T-die

The structure of the template is changed from the original O-shaped hollow structure to the m-shaped, V-shaped, N-shaped, well-shaped, and finally fixed to the well-shaped.So Gwell recommends customers choose a well-shaped T-die.

3. Vacuum Setting Table  

China Gwell is committed to the setting unit. Vacuum Setting Table has not only a cooling function but also a better forming function.

4. Cooling part

Adopt Gwell’s special cooling rollers and stress-relieving cooling beds to make the board run smoothly and fully shaped.

5. Automatic operation

The whole line adopts PLC automatic control to realize the operation of the man-machine interface. It is easy and automatic to operate.

6. PP hollow board extrusion line screen changer

A hydraulic quick screen changer is used to make the screen changing process fast and effective. Double station, special sealing structure, to ensure the stable operation of the screen changer. PP hollow packaging board equipment manufacturer’s hollow lattice board production line PP hollow packaging board equipment production line.

7. Tractor

The efficient PP hollow board extrusion line has two sets of tractors. The group tractor has high power, high reduction ratio, multi-roller type, good low-speed rotation performance and large tractive force, which can uniformly pull the board out of the vacuum setting table at the same time. The second set of tractors is used to destress the product. In addition, it is equipped with edge trimming equipment to guarantee the useful width and edge quality of the board.

8. Stress relief equipment

The large area conduction heating mode of the advanced PP PC PE Hollow Sheet Extrusion Line can effectively eliminate the board stress and further improve the flatness of the board.

9. Electric control of the whole line

advanced can realize the consistent control of all parameters of the whole line by using a microcomputer (PLC), so as to effectively optimize the operation characteristics of the whole production line. GWELL as China Plastic Extruder Supplier.

10. Extrusion die

High-quality alloy extrusion die lip and choke rod provide uniform pressure drop from die inlet to die lip. Precision machined molds ensure good quality of finished extruded sheets.

11. Vacuum calibration table

The thermal convection system of the calibration bench has a cross arrangement to ensure that the hot PC resin stream is effectively cooled and the final extrudate reaches the desired shape and exact dimensions. As far as the forming process is concerned, our multi-layer sheet extrusion machines can rapidly form by setting and cooling without the need for cold water. It helps save energy and improve efficiency.

12. Dry Vacuum Calibrator

The vacuum calibrator consists of 2 independent subsystems equipped with many closed-loop vacuum channels.

Advantages of the PP hollow board

  1. Good water resistance. Even if it is completely immersed in water for several days, it will not be deformed by moisture. Acid and alkali resistance, corrosion resistance, no decay, no rust, especially suitable for basement projects, highway and railway bridge piers, and other humid environments.
  2. Cement is not easy to stick to it. After the formwork is constructed, it is easy to demould. Will not be deformed due to cement adhesion
  3. The surface of the plastic template is smooth, and there is no need to brush the release agent, which reduces the cost of cleaning and maintenance. The surface of the construction building is smooth and flat, and no secondary modification is required.
  4. Lightweight, high efficiency, easy to open and dismantle the mold, low labor intensity of the handling operation, and high construction efficiency.
  5. High support strength, not easy to deform, impact resistance and wear resistance.
  6. Low cost. The service life is long, and the number of cycles used can reach more than 100 times. In addition, the used waste boards and leftover materials can be recycled and reused, saving costs and reducing pollution. The comprehensive use cost can be saved by more than 30% compared with traditional wooden formwork.
  7. Long life and many times of repeated use. The finally damaged plastic template can still be crushed again and reprocessed into a new template, saving resources and meeting the requirements of the “green industry”.
  8. Good thermal insulation is beneficial to shorten the construction period.
  9. The method of combining with wood can be used for various treatments, and welding can also be carried out, so secondary processing can be carried out flexibly on the construction site.
