Built to Endure PP Strapping Band Production Line Heavy Duty PP Extrusion Workhorse

This industrial backbone is engineered for uninterrupted, high-intensity production. Understanding that downtime means loss, we reject compromise at every critical durability component. The extruder's core—screw and barrel—is crafted from 38CrMoAlA alloy steel with deep nitriding treatment, achieving surface hardness up to HV1000 to withstand years of wear from PP fillers. The gearbox features integrally cast HT250 iron, annealed to relieve internal stress, with internal helical gears hardened and precision-ground for smooth, quiet operation. From the robust welded frame to brand-name bearings and seals, every detail reflects our commitment to reliability, delivering decades of stable service.

• Ultra-Wear-Resistant Extrusion Unit: Nitrided screw and barrel with deep, uniform hardness layer, offering wear life several times that of ordinary carburized treatment. Precision-ground barrel bore with optimized clearance balances plasticizing efficiency and durability.
• High-Rigidity Drive System: Gearbox gears use 20CrMnTi alloy steel with high-frequency hardened and precision-ground tooth surfaces (accuracy grade GB7), ensuring high transmission efficiency, low temperature rise, and long life. Includes built-in forced lubrication system.
• Sturdy Mechanical Structure: Main frame constructed from high-quality profiles and steel plates with reinforced design at key load-bearing points and stress relief treatment to prevent long-term deformation.
• Brand-Name Key Components: Bearings, seals, inverters, and other critical parts selected from renowned domestic and international brands, ensuring operational reliability and maintenance convenience.
