What are the differences between high-frequency welded bellows-type protective covers and ordinary protective covers

High-frequency welded bellows-type protective covers and regular protective covers exhibit significant differences in manufacturing processes, structural performance, material selection, and application scenarios. The detailed comparisons are as follows:

I. Manufacturing Process

1. High-Frequency Welded Bellows-Type Protective Cover

   • Utilizes high-frequency welding technology to bond outer PVC/TPU-coated fabric with an inner PVC skeleton.
   • Advantages:
     • High welding efficiency and speed.
     • No additional adhesives required.
     • Maintenance-free after welding.
     • Features waterproof, dustproof, oil-resistant, acid-resistant properties.

2. Regular Protective Cover

   • Employs traditional manufacturing methods, such as stitching or adhesive bonding.
   • Drawbacks:
     • Stitching may result in exposed threads or weak seams prone to breaking.
     • Adhesives may degrade over time, reducing protective performance.

II. Structural Performance

1. High-Frequency Welded Bellows-Type Protective Cover

   • Long stroke, small compression ratio: Minimum compression ratio of 1:10, adaptable to导轨 of varying lengths while saving space.
   • Superior sealing: Effectively blocks dust, metal chips, and debris from entering machinery.
   • Durability: Resistant to foot impact, deformation, and shock, ensuring long service life.

2. Regular Protective Cover

   • Limited stroke and compression ratio: May fail to meet requirements for specialized equipment.
   • Poor sealing: Gaps allow contaminants to infiltrate, risking equipment damage.
   • Low impact resistance: Prone to deformation or damage under external force.

III. Material Selection

1. High-Frequency Welded Bellows-Type Protective Cover

   • Materials include PVC, nylon, rubber, etc., chosen based on specific environments.
   • Properties: Resistant to coolants, oils, acids, and alkalis.

2. Regular Protective Cover

   • Limited material options, often unsuitable for harsh conditions (e.g., high temperature, humidity, or corrosive environments).

IV. Application Scenarios

1. High-Frequency Welded Bellows-Type Protective Cover

   • Ideal for high-demand environments:
     • CNC machine tools
     • Machining centers
     • Automated equipment
   • Ensures extended equipment lifespan by shielding against environmental hazards.

2. Regular Protective Cover

   • Suitable for low-demand scenarios:
     • Simple mechanical equipment
     • Hand tools
   • Provides basic protection only.
