25-30kg/h PP/PLA Extruder for Small Scale Plastic Production

25-30kg/h PP/PLA Extruder Product Introduction 

The 25-30kg/h PP/PLA Extruder for Small Scale Plastic Production is a compact, high-performance solution for manufacturing PP and PLA sheets and films. Its single or twin screw extrusion system ensures uniform melting and smooth material flow. The machine supports semi-automatic feeding, temperature-controlled extrusion, and PLC touch screen monitoring, providing stable, high-quality output for small-scale industrial production.

This extruder is widely used for producing biodegradable sheets, food packaging films, industrial prototypes, and research and development applications. Its design integrates feeding, extrusion, cooling, and winding processes in a small footprint, offering an efficient, eco-friendly, and versatile solution for small-scale plastic production.

Working Principle：

Plastic granules (PP or PLA) are fed into the hopper and transported into the extrusion barrel. The single or twin screws rotate to melt and homogenize the material. The molten plastic is forced through a die to form sheets or films, which then pass through cooling rollers for shape stabilization and surface finish. The semi-automatic feeding and PLC control ensure consistent thickness and quality for small-scale production.
