Radial Springs to Center Floating Inserts for Alignment

Progressive Components introduces Radial Springs, which lift and center floating inserts to pre-align cores before a mold's cavity interlocks engage.

Precise alignment is often required between the cavities and cores, such as with critical shutoffs or requirements for a consistent parting line match. Rather than rigidly bolting inserts to the mold base, stripper bolts enables the Radial Spring's pressure to reduce side forces and pressure on alignment locks. Previous design practices utilized disc springs to provide preload in the Z axis, but Progressive's new Radial Springs go a step further by positioning the core insert in the X and Y axis for minimal force to be experienced with the initial lock engagement.

Radial Springs are available in four sizes to fit Progressive's Stripper Bolt diameters of 1/4", 5/16", 3/8", and 1/2". For alignment purposes, Progressive offers Cavity Interlocks in both a round and a flat series.
