Product Description:

Material Advantages:

Product Name: 8-strand monofilament/8-strand braided rope (CCS certified) for marine mooring.
Material Combination: Polypropylene (PP), polyethylene (PE), polypropylene (PP) blends, polyester (PET), nylon (NYL), and other high-strength materials.
Construction: 8-strand braided, uniform linear density, high strength, and excellent tensile strength.
Main Applications: Ship mooring, cable lashing, offshore packaging and logistics securing, dock loading and unloading, and port vessel maintenance.

Manufacturing Process:

1. Raw Material Pretreatment

Material Storage and Inspection
PP, PE, polyester, nylon, and other raw materials are stored according to specifications and randomly inspected for color, particle size, moisture content, and impurities. Material certificates of conformity and chemical stability test reports required for CCS certification are also collected.

Particle Sizing and Drying
Pellets are screened and dried to control moisture content to prevent hydrolysis and air inclusion during extrusion.

Fiber Pretreatment
Preparing materials in multi-strand or monofilament form, surface treatment (such as UV protection, slip enhancement, and anti-friction) and cleaning are performed.

2. Mixing and Proportioning

Formulation Design
Determine the ratio of each component (PP/PE/nylon/polyester, etc.), fiber type, and fiber cross-sectional diameter based on product specifications.

Material Mixing
Mix different materials in a predetermined ratio to ensure color consistency and uniform physical properties.

Pre-Stretching Stretching/Microstretching (if applicable)
Preliminary pre-stretching of some filaments to improve the stability and uniformity of subsequent twisting.
III. Extrusion and Rope Forming

Compound Melt Extrusion
The mixed material is fed into the extruder, where it is propelled, melted, and homogenized to form a uniform melt.

Solidification and Shaping
The melt passes through the spinning orifice to form filaments, which are then cooled and shaped.
8-Strand Braiding
Eight monofilaments are braided at a set tension and passed through a braiding line to form an 8-strand braid.
Pre-Stretching and Tensioning
The core strands of the 8-strand braid are tensioned to ensure uniform density and avoid excessive initial elongation.
Surface Treatment
If necessary, UV protection coating, wear-resistant coating, and smooth surface treatment are applied to improve durability in seawater environments.
IV. In-Process Testing and Quality Control

Mechanical Property Testing
Tensile strength, elongation, fracture toughness, etc. are sampled according to standards. Test
Appearance and Dimensional Inspection
Measurement of diameter, rope roundness, end treatment quality, and winding consistency
Environmental Adaptability Testing
Salt spray, UV, and heat and humidity simulation tests ensure long-term reliability at sea
Traceability and Batch Management
Establish a quality traceability code for each batch of product, recording raw material batch number, process parameters, and test results
V. End Treatment and Finished Product Finishing
End Sealing
Prevent unwinding by heat sealing, knotting, or using a rapier tip
Roll Forming
Roll the finished rope into a roll according to specifications, specifying the roll diameter, roll weight, and labeling information
Labels and Certificates
Apply product information labels and include factory shipping information Test reports, material certification, CCS certificate, etc.
VI. Finished Product Inspection and Release

Factory Review
Final review against process parameters, customer specifications, and CCS certification requirements
Spot Inspection and Approval
Second spot inspection of key diameters and strength points. Only qualified products are released for storage or shipment.
VII. Packaging, Transportation, and Storage

Packaging Requirements
Packaging according to order specifications, marked with length, diameter, weight, batch, and certification information.
Storage Conditions
Keep in a cool, dry place away from light, moisture, mildew, and heat. Avoid sharp objects.
Shipping and Transportation
Load according to sea/land transport requirements to ensure cargo integrity during transportation.
