How A Plastic Extruder Works

The Production Process Of Plastic Extrusion Includes The Following Aspects:

 Feed: Plastic Granules Or Pellets Are Fed Into The Hopper At The Top Of The Extruder.

 Heating And Melting: Plastic Particles Entering The Barrel Are Heated Or Melted By The Interaction Of The Heating Element And The Rotating Screw

 Conveying And Mixing: The Melted Plastic Particles Are Conveyed And Mixed Along The Length Of The Barrel By The Rotating Screw, Which Ensures That The Plastic Is Uniform

 Pressure Step: As The Molten Plastic Continues To Move Forward During The Conveying Process, It Passes Through The Screw And Barrel To Achieve Compression

 Extrusion Stage: The Compressed Plastic Passes Through The Die At The End Of The Barrel To Obtain The Cross-Sectional Shape Required For The Extruded Product, Which Can Be Set In Advance, Such As Sheet Village, Film, Pipe, Etc.

 Cooling: The Plastic Parts Processed By The Extrusion Process Are Cooled, And This Process Usually Uses A Water Bath Or Cooling Roller To Fix The Final Shape

 Cutting Or Winding: Depending On The Setting Requirements, The Extruded Plastic Can Be Cut Into A Certain Length Or Wound Into The Required State, Which Facilitates The Next Step Of Processing

In The Plastic Extrusion Production Stage, The More Critical Components Are The Hopper, Screw, Barrel, Heating Element, Mold And Cooling System, Which Are Set According To The Different Types Of Plastics Required Or The Different Products Required To Be Extruded
