Two primary advantages distinguish servo-driven pad printers from pneumatic models.
Speed
Servo-driven machines deliver faster movements and shorter strokes, which lend themselves to higher productivity, especially when it comes to fully automated machines.
Flexibility
When processing multiple different parts on a single machine, servo units can store “recipes” for each part type. This capability reduces setup time between jobs and decreases labor costs.
The hybrid option
Hybrid machines are sometimes offered, combining servo drives on certain axes while keeping other movements pneumatic. Thorough communication about client needs and expectations is essential when selecting appropriate machinery for any application.
