Family-specific questions
What is the difference between guide pins and locating pins?
Guide pins provide continuous alignment through repeated cycles; locating pins mainly set initial position.
Can guide pins be used without guide bushings?
In most mold applications, pins work with bushings to maintain precision and reduce wear.
What factors affect guide pin service life?
Material quality, surface treatment, lubrication and fit with the mating bushing all affect service life.
