Features & Advantages

• Key Difference: Conductive casters must ensure a low-resistance pathway, while anti-static casters focus on controlling the speed of charge release. For example, the graphite microcrystal structure in carbon fiber allows π electrons to move freely, forming an efficient conductive network. In contrast, the electrons in ordinary plastics are bound by covalent bonds and cannot conduct electricity.

• 2. Causes of Material Differences

  • Conductivity Requirements: In environments where rapid current conduction is needed (e.g., power supply for bumper cars), conductive casters use low-resistance materials (e.g., carbon fiber composites). Anti-static casters, which only need to release weak static charges, can use high-resistance polymers.
  • Durability and Environmental Adaptability:
    • Conductive casters often incorporate wear-resistant polyurethane to ensure long-term use on epoxy floors without shedding.
    • Standard casters, without special formulations, are prone to slipping or aging in damp or oily environments.

Application Scenarios

• Electronics Manufacturing

  • Transporting PCB assembly carts, server racks, and semiconductor handling equipment in ESD-protected areas (EPAs).

• Medical & Laboratory Equipment

  • Moving diagnostic machines, analytical instruments, and mobile medical carts in hospitals and labs.

• Automotive EV Battery Production

  • Used in battery module assembly lines to prevent static damage to battery management systems (BMS) and cells.

• Aerospace & Defense

  • Handling avionics, communication systems, and other sensitive electronic assemblies in cleanroom environments.

3. Performance Comparison and Selection Recommendations

Selection Principles:

• If direct current conduction is required (e.g., equipment grounding) → Choose conductive casters (resistance 10³–10⁵Ω).
• If only static prevention is needed → Anti-static casters (resistance 10⁶–10⁹Ω) are more cost-effective.
