In high-precision industries such as electronics manufacturing, semiconductors, and medical equipment, electrostatic discharge (ESD) remains a critical factor affecting product quality and operational stability.If static electricity is not effectively dissipated:
Minor cases may lead to equipment malfunction,While severe cases can damage sensitive components and impact overall production yield.

Therefore, establishing a reliable and low-resistance discharge path has become essential in modern industrial environments.Conductive casters are a key component of this system.

 What Are Conductive Casters?

Conductive casters are designed with conductive materials integrated into the wheel, allowing equipment to maintain a continuous conductive path to the ground during movement, enabling fast static dissipation.

Their core benefits include:

• Preventing static buildup during movement
• Rapidly dissipating electrostatic charges
• Improving production stability and yield
• Reducing equipment failure and maintenance costs

They are widely used in:

• SMT production lines
• Semiconductor manufacturing
• Precision electronics
• Medical and laboratory environments
