PLA plastic sheet extrusion machine Function
PLA Plastic Sheet Extrusion Machine
Function Overview
The PLA Plastic Sheet Extrusion Machine is designed to process PLA (Polylactic Acid), a biodegradable raw material, into high-quality plastic sheets. PLA requires specialized screw design and processing conditions to ensure optimal extrusion. The machine can be configured as either a single-screw or twin-screw extruder, depending on production requirements and material characteristics.
Key Features
Biodegradable Material Processing: Specifically designed for PLA and other biodegradable materials.
Energy Efficiency: Twin-screw extruders are recommended for power-saving and multi-purpose sheet production.
Versatility: Capable of processing various materials, including PP, PP+starch powder, PP+CACO3 powder, PET, and PS.
Advanced Screw Design: Building-block style screw design with multiple arrangements for wide application range.
Double Vacuum System: Ensures fast venting of water and moisture.
Melt Pump: Equipped with a melt pump for stable and quantitative output.
PLC Control System: Fully automated control with parameter setting, data feedback, and alarm functions.
