PU Cast Unit for Submarine Cable Blocks

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) at the target mix ratio (MOCA: 100:9-12; BDO: 100:4-6) for submarine cable fixing blocks.

1A1B Tank Loading & Temperature Setting

Load prepolymer into Tank A and chain extender into Tank B; the 1A1B independent temperature control sets Tank A at 30-80°C and Tank B per formula (MOCA: 90-115°C; BDO: 25-50°C).

Vacuum Defoaming

Activate the vacuum defoaming system to reach ≤-0.095MPa, removing bubbles for dense, pore-free cable fixing blocks that resist water flow impact and hold firmly.

Precision Metering & Casting

The PLC dynamic metering system (≤±0.3%) dispenses precisely; the mixing head runs at 7000-11000 r/min, with 80-1000 g/s flow for multi-specification cable fixing blocks.

Frequently Asked Questions

What submarine cable applications is this machine designed for?
This machine is specially designed for the production of submarine communication and power cable fixing blocks. It is widely used for casting cable fixing accessories in deep sea and offshore areas, ensuring cable stability during laying and operation.
How does the machine ensure corrosion resistance in seawater?
The machine supports the BDO hydrolysis-resistant and corrosion-resistant formula, which provides excellent seawater corrosion resistance. This ensures the cable fixing blocks maintain their structural integrity during long-term immersion in harsh submarine conditions.
How does vacuum defoaming benefit submarine cable block production?
The vacuum defoaming system maintains vacuum ≤-0.095MPa, producing dense, pore-free products. This prevents water penetration and resists water flow impact, ensuring cables are fixed firmly without loosening under high-pressure deep-sea conditions.
What is the advantage of the 1A1B independent temperature control design?
The 1A1B independent temperature control design allows precise temperature regulation for each component, ensuring stable and reliable operation. This is particularly suitable for mass production of multi-specification cable fixing blocks with consistent quality.
Can I switch between different chain extender systems?
Yes. The system supports flexible switching between MOCA and BDO chain extenders, allowing you to adjust product toughness as needed to adapt to different sea area conditions and application requirements.
How does the machine ensure quality control during production?
The PLC + touch screen control system with multi-formula storage ensures precise parameter management. The dynamic metering system (≤±0.3% accuracy) provides consistent material ratios, while real-time monitoring ensures stable operation and reliable product quality.
