Industrial Applications

1. Cleanroom Electronics Component Pick-and-Place Actuation

Utilizing the Festo DGST-6-40-PA as a highly precise vertical z-axis actuator in a gantry system for placing delicate microchips and SMD components onto PCBs.

Problem Solved

Electronics manufacturing requires actuators that do not introduce particulate contamination while maintaining high repetition accuracy for tiny components. The ISO Class 6 cleanroom suitability and <= 0.3 mm repetition accuracy resolve this issue perfectly.

2. Automated Medical Laboratory Reagent Dispensing

Implementing the mini slide in an automated laboratory fluid handling robot to repeatedly lower and raise dispensing nozzles exactly 40mm into multi-well plates.

Problem Solved

Automated pipetting systems require compact, lightweight (150g product weight) vertical motion that resists mild laboratory environments and guarantees exact positioning to avoid cross-contamination or damaging well plates.

3. Micro-Connector Press-Fitting Assembly Station

Using the yoke-style slide design to press-fit tiny electrical pins and micro-connectors into plastic housings, absorbing the lateral forces generated during the insertion process.

Problem Solved

Standard compact cylinders often fail or suffer excessive wear under side loads or torque during small-parts press-fitting. The DGST's recirculating ball bearing guide can handle up to 260 N of lateral force (Fy/Fz) and 1.2 Nm of torque, ensuring long operational life.
