Engineered Overview & Technical Deep-Dive — SB Blowing & Printing Line — 600 / 800 / 1000
Technical Architecture & Mechanical Design
The SB Blowing & Printing Line — 600 / 800 / 1000 (SB · blow + print) represents state-of-the-art blown film extrusion technology 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 (50mm) paired with bimetallic nitrided barrels (38CrMoAlA alloy, surface hardness HV950-1050) to guarantee superior plasticization, thermal stability, and melt homogeneity across all resin grade spectrums. 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 of 100–600mm and a peak throughput rating of High Capacity, 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.
Industrial Applications & Resin Processing
Engineered for high versatility, the SB Blowing & Printing Line — 600 / 800 / 1000 processes a wide spectrum of polyolefin resins and biodegradable biopolymers including HDPE, LDPE, LLDPE, Metallocene LLDPE (mLLDPE), EVA, PLA, PBAT, and recycled PE pellets. It produces high-clarity agricultural greenhouse films, heavy-duty shipping sacks, shrink packaging, laminated barrier pouch substrates, courier mailing bags, and premium retail shopping bag film. The film thickness profile ranges from micro-thin 0.008 mm garment wrap up to heavy-duty 0.25 mm industrial liner sheeting, maintaining tight gauge tolerances across the entire 100–600mm web width.

Key Engineering Innovations & Quality Assurance
CFD Spiral Die Head Geometry
Engineered spiral distribution channels prevent melt stagnation, eliminate die lines, and optimize multi-layer thickness distribution across all extrusion channels.
Dual-Lip Air Ring & IBC Bubble Cooling
High-pressure dual-chamber air ring with frequency-controlled blowers accelerates bubble cooling, increasing line speed by up to 30% while securing film bubble stability.
Automatic Tension & Corona Treater Integration
Surface treatment unit with high-frequency spark discharge prepares film surface tension (38-44 dyne/cm) for downstream flexographic printing and laminating processes.
Servo Winder with Automatic Cut & Changeover
Dual-station winder equipped with magnetic powder brake or AC servo control ensures flat, wrinkle-free film roll formation with smooth edge alignment.
⚡ Installation & Utility Requirements
Operational installation requires a dedicated 3-phase electrical supply (380V/415V, 50/60Hz) with total power consumption rated at approximately 18KW. Compressed air must be supplied at 0.6–0.8 MPa with a clean, moisture-free air dryer unit. Industrial water chilling (chilled water temperature 15-20°C, flow rate 8-15 m³/h) is required for air ring cooling coils and gearbox thermal exchangers. Floor pad loading must support minimum floor loading ratings of 3,500 kg/m² on a level reinforced concrete base.
🛠️ Preventative Maintenance Protocol
Preventative maintenance includes weekly inspection of gearbox oil levels (VG220 synthetic gear oil change every 4,000 operational hours), daily cleaning of die lip carbon deposits using soft copper scrapers, monthly lubrication of haul-off bearings and winder pivot points, and quarterly calibration of thermal thermocouples and PID controllers. Filter screen changers should be purged and cleaned per melt pressure transducer feedback.
