Foam Fender with Integrated Rope Holes for Simple Setup

Foam Fender with Integrated Rope Holes for Simple Setup

Product Description:

Material Advantages:

1. Core Foam Material: Utilizing high-density closed-cell EVA foam or cross-linked polyethylene foam, this lightweight and highly elastic material effectively absorbs the impact of berthing.

The closed-cell structure is completely non-absorbent and mold-resistant; even if the outer layer is damaged, buoyancy remains unaffected, ensuring the fender remains afloat and preventing sinking failure.

2. Outer Protection and Reinforcement Structure: The outer surface is coated with a wear-resistant polyurea layer, offering resistance to seawater corrosion, UV aging, and scratches. It withstands long-term erosion from marine salt spray and waves, protecting the internal core material from damage.

A nylon fiber mesh reinforcement layer is nested between the core material and the polyurea coating, enhancing overall structural strength and tear resistance, preventing peeling between the outer layer and core material, and distributing stress around the rope holes.

3. Integrated Rope Hole Material: The rope holes feature an integrated molding design, with hot-dip galvanized steel sleeves or high-strength engineering plastic bushings embedded in the hole walls. This prevents wear on the hole walls during rope tension, extending service life.

The core material around the rope hole is locally reinforced, and a special adhesive is used to secure the bushing to the core material and reinforcement layer, ensuring even stress distribution during rope installation and preventing localized deformation or cracking.

4. Auxiliary Materials Small stainless steel washers are added to the ends of the rope holes on some larger products to further enhance the load-bearing capacity of the holes, accommodate thicker ropes, and improve stability after installation.

All materials comply with marine environmental standards, release no harmful substances, and will not pollute the marine environment.

Manufacturing Process:

1. Raw Material Preparation and Pretreatment
The core material is closed-cell foam (commonly EVA, PE, or PU foam). Density, hardness, and weather resistance must be tested to ensure compliance with marine protection requirements.

Auxiliary materials include reinforcing fiber cloth, adhesive, and pre-embedded rope hole sleeves (usually made of corrosion-resistant plastic or metal). The sleeves need to be roughened beforehand to improve adhesion to the foam.

The foam raw materials are mixed evenly according to the formula. If it is a foamed material, the foaming agent ratio and temperature must be controlled to avoid uneven bubble formation.

2. Mold Design and Fabrication
The mold is customized according to the final dimensions, shape (commonly cylindrical or square) and rope hole positions of the fender. It is usually made of fiberglass or aluminum alloy to ensure smooth demolding.

Pre-embedded sleeves are fixed in the mold at the corresponding rope hole positions, ensuring precise and vertical positioning and a tight fit against the inner wall of the mold to prevent leakage during injection.

3. Integrated Molding Process

For casting: Inject the mixed foam material into the mold, ensuring the material completely covers the embedded sleeve to prevent gaps between the sleeve and the foam.

For compression molding: Place the foam blank into the mold, heat and pressurize to shape the blank, simultaneously compacting and fixing the embedded sleeve. Temperature (typically 80-120℃) and pressure must be controlled to ensure uniform molding density.

Monitor the mold status in real time during molding to prevent material overflow or molding defects.

4. Curing and Demolding
Control the curing time according to material characteristics (4-24 hours at room temperature or 1-3 hours at high temperature) to ensure complete cross-linking of the foam and achieving the required strength.

After curing, demold slowly to avoid damage to the fender edges or loosening of the rope hole sleeve due to rough handling.

5. Post-processing and Finishing
Remove excess edges and burrs from the fender, and sand the surface to make it smooth and burr-free.

Check the rope hole sleeves for secure fastening. If loose, inject a special adhesive to reinforce them, ensuring the rope holes do not detach under tension.

If necessary, apply a UV-resistant and corrosion-resistant coating to the fender surface to extend its outdoor lifespan.

6. Quality Inspection and Packaging

Appearance Inspection: Check the surface for cracks, bubbles, and dents. Verify the accuracy and free from deformation of the rope hole positions.

Performance Testing: Test the fender's compressive strength, resilience, impact resistance, and the tensile strength of the rope holes (must meet design load-bearing standards).

Qualified products should be cleaned and dried, then wrapped in waterproof packaging materials to prevent moisture or damage during transportation.

Features:

Foam fenders with integrated rope holes not only possess the inherent advantages of foam fenders in terms of protection and durability, but the integrated rope hole design further enhances their ease of installation and use. Here is a detailed introduction to their specific advantages:

1. **Extremely Convenient Installation and Use**

- **Simplified Installation Process**: The integrated rope holes eliminate the need for drilling or adding additional fixing accessories. During use, the fender can be directly secured to the vessel, dock, or floating hull by threading ropes through it. No specialized tools or technicians are required; a single person can complete the operation, significantly reducing preparation time before vessel berthing. Furthermore, the suspension position and angle of the fender can be flexibly adjusted through the rope holes to adapt to different vessel sizes and dock structures. Multiple fenders can also be linked together to cover a larger protected area.

- **Effortless Handling and Storage**: The lightweight foam, combined with the integrated rope hole design, facilitates easy lifting and positioning during installation and allows for easy lifting during transport without the need for heavy equipment. Its relatively compact size, unlike traditional inflatable or rubber fenders, allows for easy storage in a corner of the cabin when not in use, without taking up excessive space.

2. **Excellent and Stable Protective Performance**

- **High Energy Absorption Fender Effect:** The internal closed-cell foam (such as EVA, PE, etc.) has an energy absorption efficiency of 80%-90%. When the ship is berthed, the foam cushions the impact through compression deformation, with minimal reaction force, effectively preventing scratches, dents, and other damage to the hull and dock structure due to collisions. Furthermore, the smooth surface of the foam fender reduces wear on the hull paint compared to rubber fenders with higher friction.

- **Strongly Integrated Rope Holes and Body:** The rope holes are integrally formed with the fender body through pre-embedded sleeves, rather than being drilled later, avoiding problems such as foam cracking and structural damage that can occur with drilling. The pre-embedded sleeves are typically made of corrosion-resistant materials, tightly bonded to the foam, and can withstand the tension of rope fixing. Even under long-term stress, they are not easily loosened, ensuring that the fender will not fail due to rope hole detachment during protection.

3. **Strong Environmental Adaptability and Durability**

- **Harsh Environment Resistance**: The fender exterior is often coated with a protective coating such as polyurea. Combined with the hydrophobic properties of closed-cell foam, it resists corrosion from seawater, oil, and chemicals, as well as the aging effects of ultraviolet radiation and ozone, making it suitable for special scenarios such as oil terminals and nearshore areas. Its temperature resistance range is typically -40°C to +80°C, adapting to most marine climates.

- **Long Service Life**: Unlike inflatable fenders, it does not suffer from leakage risks or cracking and swelling issues like rubber fenders. This type of foam fender with integrated rope holes has a theoretical service life of over 20 years. Even if the surface is accidentally scratched, the internal foam will not absorb water, maintaining basic protective performance.

4. **High Overall Economic Efficiency**

- **Controllable Initial Costs**: Foam raw materials are relatively inexpensive, and the integrated molding process eliminates the need for additional rope hole assembly steps, resulting in a significant cost advantage during mass production. Compared to rubber fenders of the same specifications, the initial procurement cost is lower.

- **Low Long-Term Maintenance Costs:** This product requires virtually no special maintenance. Unlike inflatable fenders, it doesn't require regular inflation checks, nor does it need frequent maintenance of the fixing system like heavy-duty rubber fenders. Its extended lifespan reduces replacement frequency, and installation and maintenance can be completed manually, resulting in significant savings in labor and equipment costs over the long term.
