Float-Type Blow Molding Machine for 500L–5000L Plastic Water Tanks Barrels
500L 1000L 2000L 3000L 5000L Plastic Water tank Barrel Float Blow Molding Machine A core merit of float-based blow molding equipment is the well-rounded balance between "performance, efficiency and cost", rendering it ideal for production scenarios where high product dependability and large-scale output are critical. When compared with traditional manufacturing processes, it not only elevates product quality and longevity, but also slashes long-term running costs significantly, making it the preferred option for float item fabrication.

1.Accurate Molding Capability: Equipped with a MOOG wall thickness control system, the machine guarantees consistent wall thickness of float components, preventing localized thin or thick spots that would compromise buoyancy and service durability. Key parameters including injection stroke and blow molding duration are fully customizable, enabling the production of diverse float profiles (including round, oval, and irregular-shaped float tubes).
2.High-Efficiency Production Performance: The dual-station configuration supports alternating production operations to maximize output efficiency. The bottom blowing unit is designed with secondary lifting and expanding functions, which are tailored for shaping the specialized structures of float products. Automated product retrieval by a robotic arm minimizes manual involvement, cuts down product damage rates, and shortens the overall molding cycle.
3.Smart Control System: The equipment adopts a Mitsubishi PLC control module paired with a touchscreen HMI (human-machine interface), which provides real-time visibility of operational status and automatic fault alerts. Production parameters can be saved and retrieved on demand, streamlining production line changeovers and facilitating ongoing process optimization.
4.Versatile Adaptability Features: Core components like the die head and blow pin can be flexibly customized to accommodate floats of varying dimensions and layer configurations. The machine is also compatible with a range of raw materials such as HDPE, fulfilling the stringent requirements for float corrosion resistance and anti-aging properties.
1.Cutting-Edge Technology & Stable Molding Performance: The multi-layer co-extrusion technology boosts the float’s structural toughness and impact endurance; the integrated MOOG wall thickness control and servo hydraulic system ensure top-tier molding accuracy and a reduced defect rate; core parts are sourced from globally renowned brands, which effectively lowers equipment malfunction risks and unplanned production halts.
2.Energy-Saving Configuration & Cost Optimization Performance: The high-efficiency servo hydraulic system delivers approximately 40% energy conservation; the dual-station design paired with automated product extraction decreases labor intensity and energy usage while boosting hourly production output; aluminum alloy molds shorten the molding period, further reducing the overall production expenditure.
3.High Customization Level & Broad Material Compatibility: Machine types and molds can be fully tailored to match specific float specifications (including dimensions, volume, and layer count); the equipment is compatible with a wide range of raw materials, meeting various performance demands of floats such as UV protection and low-temperature resistance.
4.Easy Operation & Hassle-Free Maintenance: The user-friendly touchscreen interface enables quick proficiency and reduces operator training expenses; the clear fault warning function supports rapid and efficient troubleshooting; the complete after-sales service, together with prompt spare parts provision, guarantees non-stop production operations.
