ABC Multi-layer Blown Film Line — 800 / 1000 / 1200

Technical Architecture & Mechanical Design

The ABC Multi-layer Blown Film Line — 800 / 1000 / 1200 (ABC · multi-layer) is a blown film extrusion line engineered by Wenzhou Ashal Innomech Technology for heavy-duty commercial and industrial film production. Built around a high-rigidity heavy structural frame, this line incorporates precision single/multi-screw extrusion units (45/50/45mm) paired with bimetallic nitrided barrels (38CrMoAlA alloy, surface hardness HV950-1050) for consistent plasticization, thermal stability and melt homogeneity. The die head assembly features a spiral-runner flow channel optimized via 3D computational fluid dynamics (CFD) simulation, eliminating weld lines, melt fracture, and thermal degradation. Operating with a web width range of 400–1200 mm and a peak throughput rating of 150 KG/H, the machinery utilizes a multi-stage PID digital temperature controller with solid-state relay (SSR) output to maintain thermal tolerances within ±1°C across all heating zones. Driven by heavy-duty Siemens/ABB motor drives coupled with hardened helical gearboxes (SF factor > 1.5), the line delivers continuous, pulse-free resin extrusion even during 24/7 continuous production runs under full load capacity. The upper haul-off frame features synchronized dual-side nip rollers with pneumatic clamping and micro-adjustable bubble guide rings to guarantee impeccable film bubble concentricity and tension balance.
