Modern robotics and industrial automation systems depend on precise electrical insulation, dimensional stability, and long-term durability. From robotic arms and motion systems to PLC cabinets and factory control panels, materials must perform reliably in electrically active, heat-generating, and vibration-prone environments.

Sterling Plastics supplies high-performance laminate and thermoplastic materials engineered to meet the demanding requirements of robotics OEMs, automation integrators, and industrial controls manufacturers.

Typical Applications

Plastics used in robotics and industrial controls must support accuracy, repeatability, and electrical safety across a wide range of operating conditions.

Common applications include:

• Electrical insulation for control cabinets and panels

• Structural components for robotic arms and automation equipment

• Mounting plates, spacers, and wear surfaces

• Electrical barriers and terminal board substrates

• Enclosures and insulating components near motors and drives

Material Requirements for Robotics & Controls

Automation systems introduce stresses not found in general manufacturing environments. Materials must balance mechanical strength with electrical and thermal performance.

Key material properties include:

• High dielectric strength and electrical insulation
• Dimensional stability under heat and vibration
• Resistance to oils, coolants, and industrial chemicals
• Flame resistance and low smoke generation
• Machinability for tight-tolerance components
