A company in Guangdong Province has significantly increased its film production by using a two-stage extruder.

2025-06-01

A Guangdong recycling company has achieved a production capacity exceeding 1.2 tons/hour by using a two-stage extruder to process film materials.

 

Client Background: This company primarily recycles PE/PP film, with high levels of impurities and moisture in its incoming materials.

 

Pain Points: Conventional single-screw extruders have insufficient venting capacity, resulting in a high concentration of air bubbles in the output.

 

Our Solution: We configured a two-stage recycling extrusion system:

• First-stage twin-screw extruder for plasticizing and venting
• Second-stage single-screw extruder for pressurization and molding
• Dual vacuum venting + fume purification system
• Underwater pelletizing method

Final Results:

• Production capacity reached 1.2 tons/hour
• Black spots reduced by 60%
• Dense particles, bubble-free
• Client feedback "Efficiency doubled compared to before."
