Manufacturing Process:

The production process for 1.5mm, 2mm, and 3mm 304 and 316 stainless steel wire rope slings primarily includes raw material preparation, wire drawing, strand twisting, rope closing, and post-processing.
1. Raw Material Preparation
- Procurement of Wire Coils: Select 304 or 316 stainless steel wire coils, typically with a diameter of 5.5mm or greater.
- Pretreatment: First, mechanical methods, such as repeated bending, are used to initially remove the oxide scale from the wire coil surface. The wire coil is then pickled in a mixture of nitric and hydrofluoric acids to thoroughly remove surface impurities. After cleaning, a layer of lime or borax is applied to the wire coil surface as a lubricant to absorb the lubricant and reduce friction during subsequent wire drawing.
2. Wire Drawing
- Rough Drawing: The wire coil is passed through a die through multiple rough drawing passes to quickly reduce its diameter to an intermediate size. - **Intermediate Heat Treatment**: Because the steel wire becomes hard and brittle due to cold work hardening during the drawing process, it requires annealing in a protective atmosphere, such as hydrogen, to eliminate internal stresses, reduce hardness, and restore plasticity.
- **Fine Drawing**: The annealed steel wire is finely drawn to achieve the required diameter and strength. The fine drawing process requires extremely high die precision, lubrication, and speed control.
- **Finish Heat Treatment**: Depending on the customer's specific wire properties, a final solution treatment may be required to achieve the best overall performance.
3. **Stranding**: A specific number of steel wires, such as 7 or 19, are twisted through a stranding machine. Around a central wire, surrounding wires are twisted together using a specific lay length and lay direction, such as right-hand alternate lay (ZS), to form a strong spiral structure.
4. **Rope Closing and Post-Processing**
- **Rope Closing**: Several strands, such as 6 or 8, are twisted together around a core to form a rope. Stainless steel wire ropes often use a stainless steel core or a cotton-free core, such as a polypropylene core, to prevent corrosion.
- **Stabilization**: The assembled wire rope is subjected to a tension close to 60%-80% of its breaking strength to even out internal stress, stabilize its structure, and reduce initial structural elongation.
- **Lubrication**: A specialized lubricant is used throughout the production process and on the finished product to reduce wear and corrosion.
- **Inspection and Packaging**: The wire rope undergoes a comprehensive final inspection, including diameter measurement, breaking strength testing, lay length inspection, visual inspection, and material certification, to ensure compliance with relevant standards. After passing inspection, the wire rope is wound around a spool or wooden wheel and protected to prevent damage during transportation and storage.

Features:

Dual-material corrosion resistance provides greater flexibility in application scenarios.
304 stainless steel: Provides basic corrosion resistance and can be used in dry, indoor, or slightly humid environments (such as lifting precision parts in a workshop). It offers a cost-effective solution for general lightweight sling needs.
316 stainless steel: Contains molybdenum for enhanced corrosion resistance, allowing it to be used outdoors in rain, coastal humidity, or in slightly acidic or alkaline environments (such as installing small equipment outdoors or lifting within seafood processing plants), preventing rust from affecting its strength.
Small diameter, high precision, suitable for precision lifting.
The small diameter of 1.5mm-3mm, combined with a fine wire drawing process, results in a perfectly rounded cable with minimal dimensional deviation (typically ≤±0.05mm). This makes it suitable for small slings used for lifting precision components such as electronic equipment and medical device accessories, eliminating the inconvenience and risk of collision caused by overly thick slings. The structure balances strength and operability.
The mainstream 7X7/7X19 structure is constructed from multiple strands of fine steel wire. This ensures the tensile strength required for lightweight slings (for example, a 3mm 316 stainless steel 7X19 rope has a breaking force of approximately 350kg) while also offering good flexibility, allowing for flexible adjustment of the lifting point angle to accommodate various shapes of light workpieces.

III. Sling Adaptability Value: Providing Safety for Light Lifting
Safe Adaptability: The material and structural design meet the safety standards for lightweight slings. Factory-tested for tensile strength and visual inspection, these ropes are free of broken wires and loose strands, allowing them to be directly processed into slings, eliminating safety hazards during light lifting.
Easy Processing: The small diameter rope is easily cut, braided, or combined with small rigging tools (such as mini shackles and lightweight hooks) to create custom sling lengths. This eliminates the need for complex equipment and reduces sling production costs. Long-lasting and durable: Stainless steel material does not require frequent maintenance and only requires simple daily cleaning. Compared with ordinary carbon steel ropes, its service life is extended by 2-3 times, reducing the replacement frequency of light slings.

Applications:

This 1.5mm-3mm 304/316 stainless steel wire rope, with its small diameter, corrosion resistance, and lightweight properties, is primarily used in three areas: precision lifting, light-duty operations, and civilian applications. It is particularly well-suited for light lifting applications requiring high sling flexibility and corrosion resistance.

### 1. Industrial Precision Lifting (Core Requirements: Anti-collision + Suitable for Small Loads)
- Electronic/Medical Equipment Lifting: Used for transporting electronic components (such as chip wafer cassettes) and medical device accessories (such as small diagnostic instrument parts) within the workshop. The small diameter of the rope prevents collisions with delicate components, while the 304 stainless steel resists minor dust and moisture in the workshop, preventing equipment contamination.
- Automotive/Mechanical Precision Component Assembly: Used for lifting small sensors and precision gears on automotive production lines, or for lifting micro-motor parts in mechanical manufacturing. The flexibility of the 7x7/7x19 structure allows for flexible adjustment of lifting points, ensuring precise assembly and docking of components.

### 2. Light Duty Outdoor and Special Environment Operations (Core Requirements: Corrosion Resistance + Low Maintenance)
- **Marine/Offshore Light Duty**: 316 stainless steel can be used for lifting small fishing gear (such as fishing net accessories) from fishing vessel decks and installing lightweight metal decorative components in coastal landscaping projects. The molybdenum-containing material resists corrosion from seawater salt and resists rusting over time.
- **Food/Chemical Light Duty**: Lifting small stainless steel drums (such as sauce drums) in food processing plants, or transferring small, corrosion-resistant containers in chemical workshops. Both 304 and 316 stainless steel meet hygiene standards and can withstand corrosion from food juices and minor chemical volatiles.

### 3. Residential and Home Use (Core Requirements: Safety + Ease of Use)
- **Home DIY and Decoration**: It can be used to make lightweight slings for hanging indoor plants, decorative paintings, and small chandeliers. The slender, unobtrusive 1.5mm-2mm diameter and natural stainless steel color complement a variety of decor styles and require no frequent replacement. Small Warehousing and Logistics: Used in home warehouses or small e-commerce warehouses for lifting lightweight cargo (such as clothing cartons or small tool boxes). Used with a mini hook for easy operation, the 304 stainless steel cable withstands the humid environment of warehouses.

### IV. Other Professional Lightweight Applications (Core Requirements: Specialized Adaptation)
Stage/Exhibition Construction: Used for temporary lifting of small stage lighting stands and exhibition panels. The small diameter cable provides excellent concealment without affecting the visual effect, and can withstand the light loads of lights and panels (typically 50-150kg).
Agriculture/Horticulture: Used for lifting small irrigation equipment and seedling trays in greenhouses. The 304 stainless steel cable withstands the high humidity of greenhouses, preventing rust and breakage of the cable due to moisture, ensuring safe operation.
