80FD Precision 4-Cavity PE Extrusion Blow Molding Machine

At the heart of every extrusion blow molding machine, the die head determines the ultimate quality of every bottle produced. The MEPER 80FDE-4S(100) features an advanced 4-cavity die head system with 15 independently controlled heating zones delivering 16.5kW of precision thermal management, representing a sophisticated approach to parison formation control. Each of the four die heads benefits from granular temperature regulation that enables per-cavity parison thickness adjustment, a capability critical for producing bottles with consistent wall distribution across all cavities simultaneously. The 75mm extruder feeds homogenized PE melt at 85kg/h into a die head manifold engineered for balanced flow distribution, ensuring each of the four cavities receives material at identical pressure and temperature. With a maximum mouth mold diameter of 35mm, the die head system accommodates a wide range of bottle neck geometries while maintaining the concentricity precision that automated filling and capping equipment demands. The 3-zone screw heating (15.3kW) upstream and the 15-zone die head heating downstream work in concert to create a complete thermal chain from pellet to parison.

• 15-Zone Independent Die Head Control: Each heating zone is governed by its own PID controller with real-time temperature feedback, enabling per-cavity thermal optimization that compensates for ambient conditions, material variations, and production speed changes.
• Balanced Melt Flow Distribution: The die head manifold geometry is computationally designed to deliver equalized melt pressure and flow rate to all four cavities, eliminating the cavity-to-cavity variation that plague less sophisticated multi-cavity die head designs.
• 35mm Mouth Mold Versatility: The maximum mouth mold diameter supports production of bottles with neck finishes ranging from narrow 18mm to wide 35mm openings, covering the full spectrum of closure types used across beverage, personal care, pharmaceutical, and food packaging applications.
• Per-Cavity Parison Programming: Each die head supports independent parison wall thickness profiling, enabling production of bottles with different wall distribution requirements simultaneously when running mixed-cavity molds for multi-SKU production scenarios.
• Upstream Thermal Preparation: The 75mm screw with 24:1 L/D and 3-zone heating (15.3kW) delivers thoroughly plasticized PE resin to the die head, eliminating unmelted particle issues that cause die head flow disruptions and parison inconsistency.
• Quick Die Head Disassembly: The die head assembly is designed for efficient disassembly and cleaning during material changes, with accessible heating band connections and documented torque specifications for reassembly to ensure rapid return to production.
• Thermal Stability Validation: 0.14kW active fan cooling at critical locations prevents heat migration that could disrupt the precision thermal balance achieved by the 15-zone die head heating system during extended production runs.

The precision die head technology in the 80FDE-4S(100) makes it particularly suitable for applications where bottle dimensional consistency directly impacts downstream process efficiency and end-product quality. High-speed filling lines operating at hundreds of bottles per minute depend on neck finish consistency within micron-level tolerances; the machine's 15-zone die head control delivers the parison uniformity that produces bottles meeting these demanding requirements. Multi-cavity production of bottles destined for different filling line setups benefits from per-cavity parison adjustment that allows each cavity to produce bottles optimized for its specific downstream process. Applications requiring bottles with intentional wall thickness variation, such as containers with grip panels or decorative features, leverage the per-cavity programming capability to achieve design intent consistently across all four cavities. Contract manufacturers serving diverse customers appreciate the 35mm mouth mold versatility that enables producing bottles for different closure systems without major die head reconfiguration.

Each 80FDE-4S(100) die head system undergoes individual calibration and validation including thermal uniformity mapping across all 15 zones (target: less than or equal plus or minus 2 degrees C deviation), cavity-to-cavity parison weight consistency testing (target: less than or equal 1.0% variation), and die head flow balance verification using instrumented pressure transducers at each cavity port. Export packaging provides specialized protection for the precision die head assembly with impact-isolated mounting within the main machine crate, VCI anti-corrosion treatment on all flow surfaces, and sealed protective covers on die head orifices. Delivered accessories include die head disassembly and reassembly toolkit with calibrated torque wrench, spare heating bands and thermocouples for all 15 zones, die head cleaning kit, and detailed English-language die head maintenance manual with thermal profile documentation. CE and ISO9001:2008 certificates. Standard 12-month warranty including die head system; on-site die head setup and process optimization service available.
