15-Zone Precision Die Head Heating Blow Molding Machine

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) die head thermal management system represents the pinnacle of extrusion temperature control, with 15 independent heating zones delivering 16.5 kW of precisely regulated power. Each zone incorporates a dedicated PID controller with thermocouple feedback, maintaining setpoint accuracy within ±1°C across the entire die head assembly. This granular temperature control eliminates the hot spots and cold zones that cause parison thickness variation and surface defects in less sophisticated heating systems.

• 15 Independent PID Heating Zones: Each die head heating zone operates under closed-loop PID control with dedicated thermocouple feedback, enabling zone-specific temperature optimization for complex parison profiles.
• 16.5 kW Total Die Head Heating Capacity: Abundant heating power with fine control granularity ensures rapid heat-up from cold start and immediate response to temperature disturbance during production cycling.
• ±1°C Setpoint Accuracy: Precision thermocouple placement and fast-cycling solid-state relays (SSR) maintain tight temperature bands, eliminating the ±5°C swings of contactor-based heating systems.
• Zone-Specific Temperature Profiling: Independent zone control enables graduated temperature profiles from die head entry (higher) to exit (lower), optimizing melt viscosity for parison formation.
• Thermal Overshoot Prevention: Advanced PID auto-tuning algorithms with feed-forward prediction prevent the temperature overshoot during heat-up that degrades polymer at the die head wall interface.

Manufacturers of high-clarity bottles and containers where surface defects from thermal variation are unacceptable. The precise thermal control benefits producers of containers with complex geometries requiring programmed parison wall thickness distribution. Medical, cosmetic, and premium beverage packaging applications where visual quality directly impacts brand perception particularly benefit from the thermal precision.
