Step One:  Manufacture Required Masterbatch granule


1.  Determine the granulation formula according to the requirements of the product

2.  Weigh PE and additives separately according to the ratio of granulation formula

3.  Mixing the PE and the auxiliary agent according to the feeding sequence and the mixing time required by the process in an internal mixer

4.  Put the mixed mass into the hopper of the granulator and extrude according to the required extrusion process parameters and process flow

5.  Cutting particles with air-cooled die surface, cool

6.  the two-stage cyclone cylinder

7.  Filter with vibrating screen and cool further

8.  Enter the storage barrel for weighing, packaging and labeling and warehousing.


The types of common master batches are generally divided into cross-linked master batch, foaming master batch, filling master batch, flame-retardant master batch, conductive master batch, color master batch etc.

Step Two:  Manufacture Required Masterbatch Sheet


1.  Determine the granulation formula according to the requirements of the product

2.  Weigh PE and Masterbatch granule according to the ratio of granulation formula

3.  Mix the PE and the required masterbatch into the mixer and stir regularly

4.  Plasticizing extrusion according to the required extrusion process parameters and process

5.  Calendering with three-rolls

6.  Cooling, cutting, drawing, winding, weighing, packing and labeling, sending into storage


Step Three: Heating and Foaming


1.  Select the master sheet according to the production requirements

2.  Set the relevant parameters according to the foaming process requirements

3.  The technological process is first cross-linked through the preheating section of the foaming furnace, and then through the plastic foam sheet machine to cool and correct the static electricity.

4.  Cooling stereotype

5.  Correction, trimming, traction, static elimination, fixed length, winding
