1. Precise Molding Performance: Fitted with a MOOG wall thickness control system, the machine ensures uniform wall thickness for float parts, avoiding localized thin or thick areas that could impair buoyancy and operational longevity. Critical parameters such as injection stroke and blow molding time are fully adjustable, allowing for the manufacture of various float configurations (including round, oval, and irregular float tubes).
2. High-Output Production Capacity: The dual-station design enables alternating production processes to boost output efficiency to the maximum. The bottom blowing mechanism is integrated with secondary lifting and expanding functions, customized specifically for forming the special structures of float products. Automated product handling via a robotic arm reduces manual intervention, lowers product damage rates, and shortens the total molding cycle.
3. Intelligent Control System: The equipment is equipped with a Mitsubishi PLC control unit combined with a touchscreen HMI (human-machine interface), offering real-time display of operational conditions and automatic fault notifications. Production parameters can be stored and retrieved as needed, simplifying production line transitions and supporting continuous process improvement.
4. Flexible Adaptability: Core components including the die head and blow pin can be flexibly modified to suit floats of different sizes and layer structures. Additionally, the machine is compatible with multiple raw materials like HDPE, meeting the strict demands for float corrosion resistance and anti-aging performance.
1.Advanced Core Tech & Steady Molding Capability: The multi-layer co-extrusion process enhances the float’s structural rigidity and impact resistance; the integrated MOOG wall thickness control mechanism and servo hydraulic setup secure superior molding precision and minimize product defect rates. Core components are selected from world-famous suppliers, significantly reducing equipment failure risks and unplanned production interruptions.
2.Energy-Efficient Setup & Cost-Saving Performance: Equipped with a high-efficiency servo hydraulic system, the machine achieves around 40% energy reduction. Its dual-station structure combined with automatic product picking lowers labor intensity and energy consumption while improving hourly throughput. Aluminum alloy molds cut down the molding cycle, further optimizing the overall production cost.
3.Excellent Customization & Wide Material Adaptability: Both machine models and molds can be fully customized to meet specific float requirements, including size, capacity, and layer quantity. The equipment is compatible with a broad spectrum of raw materials, satisfying diverse performance needs of floats like UV resistance and low-temperature tolerance.
4.Intuitive Operation & Convenient Maintenance: The user-friendly touchscreen interface allows for quick mastery, reducing operator training costs. The clear fault alarm function facilitates fast and effective troubleshooting. Comprehensive after-sales services, coupled with timely spare parts supply, ensure uninterrupted production operations.
1.Professionalism Tailor-made specifically for float production, this equipment integrates a bottom-blow system with an expansion function, specially designed to shape the hollow and irregular structures of float products. This dedicated configuration effectively addresses the incompatibility issues arising when conventional blow molding machines are utilized in float manufacturing workflows.
2.Stability Constructed with a robust heavy-duty steel frame and equipped with linear guide rail systems, the machine guarantees steady mold clamping and injection movements at all stages. Furthermore, its die head is equipped with accurate temperature control parts, which ensure uniform plasticization of raw materials and thus deliver consistently premium-quality float products.
3.Durability Key components like the screw and die head are crafted from high-strength wear-resistant alloy, boasting excellent fatigue resistance and abrasion durability. This high-quality component design not only prolongs the overall operational lifespan of the equipment but also renders it ideally suited for 24-hour continuous production runs.
4.Environmental friendliness Adopting advanced servo energy-saving technology and electric heating units, the machine realizes remarkable reductions in energy usage and carbon footprints. Moreover, it is compatible with recycled raw material feeds, fully complying with the stringent requirements of eco-friendly and sustainable manufacturing practices.
1.Aquaculture Sector: Specializes in producing fishing net floats, cage buoys, and aquaculture platform flotation units, along with supporting fishing net parts. Suitable for both freshwater and brackish water cultivation settings, these products offer dependable anti-corrosion performance and consistent buoyancy retention during extended use.
2.Marine Transportation & Leisure Field: Caters to the manufacturing of yacht harbor bumpers, floating dock assemblies, water-crossing floating passages, and rafts for aquatic theme parks. With outstanding load-bearing capability and structural steadiness, these flotation solutions excel in environments with varying water levels.
3.Marine Engineering Industry: Develops flotation platforms for water-based construction work, buoyancy components for dredging operations, environmentally friendly floating islands, and navigation beacons. The end products boast excellent impact resistance and high adaptability to the severe and complicated operating conditions of marine areas.
4.Other Application Fields: Encompasses the production of water safety buoys and fishing detection floats, which can be tailored with unique color patterns and identification labels to meet the specific functional requirements of diverse clients.
