Where Do ServoWeld® Actuators Perform Best?

Compact servo actuators are commonly used for resistance spot welding applications due to their reliability and force repeatability. Servo actuators play a crucial role in controlling the movement and force applied during resistance spot welding, offer greater control in applications such as electronics, aerospace and automotive manufacturing.

What are the factors of weld performance optimized by Tolomatic servo actuators?

Tolomatic’s ServoWeld actuators are designed for best-in-class performance with the factors that are most important for resistance spot welding gun applications.

  • Number of welds(product life): Tolomatic’s roller screw design has the highest dynamic load rating for more welds than competitive technologies like other roller screws, ball screws or pneumatics.
  • Force repeatability: Tolomatic’s unique motor design minimizes motor cogging and provides highly repeatable actuator force – ±3% over the lifetime of the actuator.
  • Efficiency: All elements of actuator (winding, screw, rod scraper, bearings) are designed to provide the most energy efficient solution on the market.
  • Welds per minute: All elements of the actuator are designed for long life and to run as cool as possible in welding applications.
  • Weight: Tolomatic integrated servo actuators minimize weight when designed into the weldgun. Additionally, Tolomatic can customize actuators for specific weldgun applications to provide industry leading light weight designs.
  • Lifetime cost: By optimizing long life, efficiency and welds per minute, Tolomatic actuators provide the lowest total cost per spot weld.
