Nylon Drag Chain: Lightweight "invisible Armor" For Industrial Flexible Protection

In The Field Of Protection For Cables And Pipelines, Which Are The "blood Vessels And Nerves" Of Industrial Equipment, Nylon Drag Chains Are Becoming The "flexible Armor" In Light Load High-frequency Scenarios Due To Their Lightweight And High Flexibility Characteristics, In Addition To The "rigidity And Hardness" Of Steel Aluminum Drag Chains. This Drag Chain, Which Uses Engineering Plastics As Its Core Material, Is Rapidly Becoming Popular In Fields Such As Automation Equipment And Precision Machinery Due To Its Unique Advantages.

1、 From Material To Structure: The 'Flexibility Gene' Of Nylon Drag Chain

The Core Material Of Nylon Drag Chains Is Modified Nylon (PA), Which Is Optimized By Adding Glass Fibers, Toughening Agents And Other Formulations. It Retains The Lightweight (density Only 1/7 Of Steel), Wear Resistance (friction Coefficient 0.1-0.3), And Corrosion Resistance (oil And Weak Acid Resistance) Characteristics Of Nylon, While Improving Rigidity And Fatigue Resistance (able To Withstand More Than 1 Million Reciprocating Motions). Its Structure Adopts Modular Design: The Chain Links Are Connected By Pin Shafts And Can Bend Freely; The Internal Cavity Can Be Customized With Partition Plates To Avoid Cable Entanglement; Smooth Surface Without Burrs, Reducing Motion Resistance.

2、 The "cost-effective Choice" In Light Load High-frequency Scenarios

Compared With Steel Aluminum Drag Chains, The Advantages Of Nylon Drag Chains Are Concentrated In "light, Static, And Economical":

• LightweightThe Weight Per Meter Is Only 1-3kg (about 5-15kg For Steel Aluminum Drag Chains), Significantly Reducing Equipment Load, Especially Suitable For Weight Sensitive Scenarios Such As Robotic Arms And Small CNC Machine Tools;

• Low NoiseThe Self-lubricating Property And Flexible Structure Of Nylon Make The Operating Noise ≤ 55 Decibels (about 65-75 Decibels For Steel Aluminum Drag Chains), Which Meets The Quiet Requirements Of Precision Workshops And Laboratories;

• Easy MaintenanceOpen Or Quick Detachable Chain Link Design, Supporting Single-sided Opening For Maintenance Without The Need For Overall Disassembly, Saving Downtime.

Its Weakness Lies In Its Load-bearing Capacity Limit (the Maximum Load-bearing Capacity Of A Single Section Is About 50kg, And The Steel Aluminum Drag Chain Can Reach Over 200kg), Making It More Suitable For High-frequency Motion Scenarios With Fewer Cables And Lighter Weight (such As Signal Lines And Thin Oil Pipes).

3、 Application Scenarios And Key Selection Factors

Typical Applications Of Nylon Drag Chains Include:

• Automated Production LineCable Protection For Collaborative Robots And AGV Carts, Suitable For 360 ° Rotation And Fast Start Stop;

• Precision Machine ToolLightweight Equipment Such As Carving Machines And 3D Printers To Avoid The Impact Of Metal Drag Chain Vibration On Processing Accuracy;

• Electronic DevicesTesting Instruments And Medical Robotic Arms Meet The Requirements Of Clean Workshops For Corrosion Resistance And Low Dust.

When Selecting, Three Key Points Should Be Focused On:

1. Temperature Resistance RangeOrdinary Nylon Drag Chains Have A Temperature Resistance Of -40 ℃~+100 ℃, And Glass Fiber Reinforced (+120 ℃) Should Be Selected For High Temperature Scenarios;

2. Bending RadiusAccording To The Equipment Travel Selection, The Common Radius Is 50-300mm, Which Is Too Small And Can Accelerate Material Fatigue;

3. Cavity SizeThe Total Cross-sectional Area Of The Cable Should Be Less Than 70% Of The Drag Chain Cavity, With Reserved Expansion Space.

From The "steel Tough Guy" To The "flexible Pioneer", Nylon Drag Chains Have Filled The Gap Of Steel Aluminum Drag Chains In Light Load High-frequency Scenarios With Their Lightweight, Low-cost, And Easy To Maintain Characteristics. With The Upgrading Of Industrial Equipment To Precision And Intelligence, This "invisible Armor" Is Becoming The Key Supporting Role Of Flexible Automation, Guarding The "nerve Vein" Of Equipment With Flexible Force.
