Industrial Applications

1. Compact Pneumatic Manifold Routing

Connecting miniature control valves to cylinders on a crowded automation manifold [4.2.4]. The 360-degree rotation of the elbow joint allows 4mm tubing to be organized cleanly without risk of kinking.

Problem Solved

Prevents mechanical stress on the pneumatic tubing and localized pressure drops caused by tight, forced routing angles.

2. Cleanroom Semiconductor Sorting Systems

Directing compressed air lines in pick-and-place sorting machinery that handles delicate wafers. The fitting's ISO Class 4 cleanroom and LABS (PWIS-free) compliance make it ideal for preventing particulate contamination.

Problem Solved

Eliminates contamination risks from paint-wetting impairment substances and microscopic airborne particulates in sensitive silicon handling zones.

3. Vacuum Gripper End-of-Arm Tooling (EoAT)

Interconnecting vacuum channels on automated robotic gripper plates. The capability to withstand negative pressures down to -0.95 bar allows reliable hold paths for suction cups.

Problem Solved

Guarantees a secure, leak-free vacuum holding line under dynamic robotic acceleration, eliminating product drops in packaging lines.
