Piab Spring Loaded Docking Pins Review: Specs, Price and Applications

Piab spring-loaded docking pins align EOAT with the mold in insert molding and in-mold labeling (IML), where several processes often run at once and precise accuracy is needed.
They provide accuracy of ±0.001 in, are sized to fit the EOAT, robot and mold, can dock on existing mold locators and are available in custom lengths, strokes and diameters.
Quick Verdict
A precise, simple solution for registering EOAT to the mold, essential for consistent label and insert placement.

Design and Operating Principle
Robots repeat well but molds and platens vary slightly with temperature and wear. Docking pins mechanically register the EOAT to the mold each cycle, compensating for small errors.
Spring loading lets the pins engage gently and absorb small misalignments without damaging the mold.
Using existing mold locators avoids modifying the mold.
Integration and Selection
Specify pin length, stroke and diameter to match EOAT and mold locators. Program the robot to dock before placing labels or inserts.
Inspect pins regularly for wear.
