Ejector Pins
During plastic injection molding and die
casting operations, no other single mold or die
component takes the beating ejector pins take.
They’re always on the move. Always fighting
friction. Thermal stress. Mechanical stress. And
therefore, they’re always in danger of galling,
seizing, bending or breaking if they’re not made
of high quality steel with uniform strength - if
they’re not hot-forged properly - or if they’re
not nitrided to exact specifications for case
depth and hardness. Heads annealed for easy
machining.

Ejector Sleeves
D-M-E ejector sleeves are made of the finest
grade nitriding steel. They are gun drilled, finish
reamed and honed for accurate concentricity
of O.D./I.D. over full bearing length. The
heads are hot-forged for uniform, consistent
tensile strength and longer mold life. The
outside surface is nitrided to a hardness of
min. 950 HV 0,3 and is honed to minimize
wear and give trouble-free performance. Your
D-M-E Service Center stocks a wide range
of diameters and lengths to suit a variety of
applications.

Flexible Cores
Manufactured from spring steel this unit allows
the release of small undercuts. It is activated by
the ejector plates as a standard ejector. They
come with a reference plane and a conical
fixing system, which saves cutting the flexible
core to fix it.
