Product Overview
Specially designed for the production of submarine communication/power cable fixing blocks, widely suitable for casting of cable fixing accessories in deep sea and offshore areas.
This PU cast unit is purpose-built for manufacturing cable fixing blocks used in submarine communication and power cable systems. The 1A1B independent temperature control two-component system supports both MOCA and BDO chain extender processes, with the BDO hydrolysis-resistant formula delivering excellent seawater corrosion resistance for long-term immersion in harsh submarine conditions. Vacuum defoaming (≤-0.095MPa) ensures dense, pore-free products that resist water flow impact and fix cables firmly without loosening. The system supports flexible switching between dual chain extenders, allowing product toughness adjustment to adapt to different sea area requirements. With stable and reliable operation, the machine is ideal for mass production of multi-specification cable fixing blocks, ensuring the stability of submarine cable laying and operation.
Operation Workflow
Raw Material Preparation
Prepare CPU prepolymer and chain extender (MOCA or BDO) according to the target mix ratio. Select the appropriate formula based on the specific sea area application requirements.
Tank Loading & Independent Temperature Setting
Load prepolymer into Tank A and chain extender into Tank B. The 1A1B independent temperature control system allows precise setting: Tank A at 30–80°C, Tank B according to selected formula (MOCA: 90–115°C; BDO: 25–50°C).
Vacuum Defoaming
Activate the vacuum defoaming system to achieve vacuum level ≤-0.095MPa, thoroughly removing bubbles to ensure dense, pore-free products that can withstand high water pressure and flow impact in deep-sea environments.
Metering, Mixing & Casting
The PLC-controlled dynamic metering system (accuracy ≤±0.3% full range) dispenses materials precisely. The mixing head operates at 7000–11000 r/min for homogeneous blending. The pouring rate is adjustable within 80–1000 g/s to accommodate different cable block sizes and specifications.
