4 Sets Rigid Frame Industrial Extrusion Blow Molder

The 80FDE-4S(100) is a high-performance industrial extrusion blow molding machine engineered for precision and efficiency in plastic packaging production. Featuring a robust 4-die head setup and an advanced 75mm screw diameter, this machine delivers consistent plasticizing capacity (HDPE 85 Kg/h) and a maximum container capacity of 500ml. Designed for high-speed automated operations, it ensures exceptional wall-thickness uniformity, energy efficiency, and reliable continuous output for industrial manufacturing lines.

The 80FDE-4S(100) derives its exceptional molding precision from 8.6 tons of strategically distributed structural mass. This is not merely weight for weight's sake—the cast iron base, thick-gauge welded steel frame sections, and oversized tie-bar assemblies create a vibration-damping foundation that isolates the molding process from ambient factory floor disturbances. Natural frequency analysis during design ensured the machine's resonant frequency lies well above operational excitation frequencies, preventing harmonic amplification of molding forces.

• 8.6-Ton Distributed Structural Mass: Strategic mass distribution across the machine base and frame creates inherent vibration damping that isolates the molding process from factory floor disturbances.
• Stress-Relieved Cast Iron Base: Normalized cast iron machine base with precision-ground mounting pads provides a dimensionally stable foundation that maintains alignment through thermal cycling.
• Robotic-Welded Steel Frame: Automated welding with post-weld stress relief ensures consistent frame geometry and prevents the progressive distortion that plagues manually fabricated lighter-gauge frames.
• Above-Resonance Natural Frequency: Design-phase FEA analysis positioned the machine's natural frequency above 30 Hz—well clear of operational excitation from the 22 kW motor and hydraulic system.
• Precision-Ground Mounting Surfaces: All module-to-frame mounting interfaces are ground flat within 0.05mm, ensuring precise component alignment during assembly and throughout the machine's service life.

Manufacturers operating in multi-story factory buildings where floor vibration transmission affects neighboring precision equipment. Production facilities in seismic zones benefit from the machine's inherent structural stability. High-precision container applications where even micron-level mold movement during clamping causes visible parting-line defects.

Export-standard fumigated wooden crate packaging with reinforced steel strapping protects the 80FDE-4S(100) during ocean freight. Critical components are separately wrapped in VCI (Volatile Corrosion Inhibitor) film. The complete package includes a tool kit, spare parts kit, and comprehensive English-language technical documentation.
