Precision Waste Plastic Bottle Baling Die Mold Steel Fixture Engineering
This heavy-duty waste plastic bottle baling chamber features wear-resistant alloy steel lining plates, guided wire tying channels, and hydraulic bale ejection mechanisms. Engineered for 315-ton hydraulic compaction, it provides maximum volume reduction, prevents plastic rebound, and allows fast manual or automated strap tying.
Use Case
The waste plastic bottle baling chamber and fixture system integrates into 315-ton four-column hydraulic presses to compact loose PET, PP, and HDPE containers into high-density bales. Integrated strap tying channels allow operators to secure bales under full compression, simplifying transport and downstream recycling operations.
