A25/30/38 PVC Boat Fender for Type a Colorful Buoy

A25/30/38 PVC Boat Fender for Type a Colorful Buoy

Product Description:

Material Advantages:

Core material: PVC (Polyvinyl chloride)
The basic components are based on PVC resin, combined with plasticizers, stabilizers and other additives to balance flexibility and durability.
The common production processes are thermoplastic molding or blow molding. The surface is mostly treated to be smooth, and some are coated with anti-UV coatings.
Key characteristics of materials
Waterproof and corrosion-resistant: Does not absorb water, is not easily eroded by seawater or oil stains, and is suitable for use in Marine water scenarios.
Buffering and shock absorption: It has excellent elasticity and can effectively absorb the impact force when ships are docked, protecting the hull and the wharf.
Lightweight and portable: With a density lower than that of metal, it is light in weight and easy to install, disassemble and store.
Color stability: Special color masterbatch is added, making the color bright and resistant to ultraviolet aging. It is not easy to fade even after long-term outdoor use.
Cost-friendly: Compared with materials like rubber, PVC has a lower raw material cost and a higher cost performance.
Auxiliary structure and material matching
The interior is filled with more high-pressure air (inflatable) or closed-cell foam (solid type) to enhance the buffering effect.
The connection parts may be equipped with nylon ropes, stainless steel hooks and other accessories to enhance the installation firmness.

Manufacturing Process:

1. Raw material preparation and mixing
Mix PVC resin, plasticizer, stabilizer, UV absorber, color masterbatch and other raw materials according to the formula to ensure uniform color and weather resistance.
The raw materials are thoroughly mixed through a high-speed mixer for stirring and heating, forming a uniform PVC mixture (in powder or granular form).
2. Forming processing (Core step)
The mainstream process is blow molding: the PVC mixture is put into the blow molding machine, heated and melted, and then the tubular blank is extruded through the mold opening.
High-pressure air is introduced into the blank to make it expand and adhere to the inner wall of the mold. After cooling, it is shaped into the required form of the buoy (such as cylindrical or spherical).
Some small-sized products are formed by thermoplastic pressing. Through the pressure and heating of the mold, the shape of the product is directly shaped.
3. Post-processing
After cooling and demolding, trim the excess corners and burrs of the product to ensure a smooth surface without any flaws.
If it is an inflatable type, install the valve stem and carry out sealing treatment. Solid type does not require this step.
The surface is coated with an anti-UV protective layer (for some products) to enhance the outdoor aging resistance.
4. Assembly and Inspection
Assemble auxiliary accessories such as nylon lanyards and stainless steel hooks to ensure that the installation function meets the standards.
Conduct multiple tests: air tightness test (inflatable), dimensional accuracy measurement, appearance inspection (no cracks, color difference), and impact resistance test.
Qualified products are cleaned, packaged, and marked with specification parameters before being stored in the warehouse.

Features:

The core features of the PVC Boat Fender for Type A Colorful Buoy are "practical protection + bright colors + wide adaptability scenarios", precisely matching the protection requirements of ship berthing.

1. Core protective performance
- High elastic buffering: The PVC material has an excellent inherent resilience, which can efficiently absorb the impact force from collisions during the mooring and navigation of ships, preventing the hull from being scratched and damaged by the dock or other vessels.
- Weather resistance and corrosion resistance: Resistant to ultraviolet rays, seawater erosion, and not easily contaminated by oil stains. It is not prone to aging, cracking or fading even after long-term outdoor or Marine use.
- Stable and durable: High material strength, combined with a tight sealing process (inflatable) or solid structure (solid type), it is tear-resistant, compression-resistant, and has a long service life.

2. Practical and convenient features
- Lightweight and easy to operate: PVC has a low density and the product is lightweight. It can be installed, disassembled and moved by a single person without the need for complex tools.
- Flexible installation: Compatible with various fixation methods such as nylon ropes and hooks, and the installation position and quantity can be adjusted according to the size of the ship and the environment of the wharf.
- Simple maintenance: The surface is smooth and easy to clean. Once stained, it only requires a simple wipe. The inflatable product is convenient for pressure replenishment and does not need frequent maintenance.

3. Appearance and Additional advantages
- Bright and eye-catching colors: With the addition of dedicated color masterbatches, the colors are rich (such as red, yellow, blue, etc.), which not only looks beautiful but also enhances the ship's visibility on the water surface, increasing navigation safety.
- Strong shape adaptability: Type A models are mostly classic structures such as cylindrical and spherical shapes, which fit the hull curves perfectly, providing no blind spots in protection and are suitable for various medium and small-sized ships.
- High cost performance: The raw material cost of PVC is moderate, and the production process is mature. Compared with materials such as rubber, the product price is more advantageous, balancing performance and budget.

Applications:

The PVC Boat Fender for Type A Colorful Buoy is mainly applied in "ship protection + water scene adaptation", covering all kinds of water mooring and navigation protection needs.

1. In the field of civilian ships
- Small and medium-sized private vessels: Suitable for yachts, motorboats, fishing boats, assault boats, etc., used for hull protection when moored at docks or along the shore to prevent scratches and wear.
- Leisure cruise boats/sightseeing boats: Sightseeing cruise boats on lakes and rivers in scenic areas enhance recognition through bright colors while also buffering the impact force when boats meet or dock.
- Fishing vessel operation: Small nearshore fishing vessels, capable of withstanding collisions during mooring at fishing ports and loading/unloading goods, and resistant to seawater corrosion, are suitable for fishery operation environments.

2. Commercial shipping sector
- Passenger ferries/transport boats: Short-distance cross-river and cross-sea ferries, fixed-route transport boats at docks, installed in batches for continuous protection during frequent berths, and to extend the service life of the hull.
- cargo ship assistance: When small cargo vessels (such as inland waterway cargo ships and coastal barges) dock at the loading and unloading wharf, protect the Cargo area of the hull from impact and avoid damaging the wharf facilities.
- marina (marina) Accessories: Yacht marina, ship mooring area, provided as standardized protective accessories for mooring vessels, uniformly adapting to the protective needs of vessels of different sizes.

3. Special Waters and Scenes
- Waterborne engineering operations: Waterborne construction vessels, salvage vessels and other operation vessels, when docking or operating in the operation area, buffer collisions with other equipment and the shore.
- Port/wharf protection: As a temporary or fixed edge protection component of the wharf, it assists in buffering when large vessels berth or protects the wharf's anti-collision facilities.
- Water sports event support: For water sports events such as sailing races and jet ski races, it is used for marking the course boundaries (with bright colors) and also to prevent competing vessels from colliding with the course facilities.
