Blade Ejector Pins
A thin rectangular working end reaches narrow ribs and restricted ejection areas. Blade orientation and the transition to the shank require close attention.

Material options
Select SKD61, stainless steel or tool steel for mold temperature and corrosion duty.
Send inquiry now →Industries and operating scenarios
The flat blade increases contact area to spread ejection force—suited to thin walls, narrow slots and complex areas where round pins cannot fit, helping reduce ejector marks, deformation and scratches; the non-round section can also resist rotation during ejection.

Materials and treatment options
Blade ejectors in narrow ribs need balanced strength and toughness; blade width, thickness and shank follow mold space and force.

-
SKH51
An HSS option; balance wear, toughness and heat treatment, and verify standards before substitution.
-
SKD61
A hot-work steel option assessed for mold temperature and toughness; specify nitriding separately.
Surface treatments and finishes
Blade faces may be polished or nitrided; thin sections need straightness control after treatment.

-
Grinding and polishing sliding surfaces
Specify roughness separately for sliding sections and part-contact tips while preserving head and orientation datums.
-
Nitriding option
Confirm suitability, treated areas and case depth for the chosen steel; recheck diameter and thin-section distortion.
Family-specific questions
Where are blade ejector pins used?
Narrow ribs, deep slots or tight spaces needing a thin ejection edge—confirm blade orientation and shank transition.
How to reduce blade pin breakage?
Control aspect ratio, grade and heat treat; ensure guidance and contact area—avoid over-treating thin sections.
What to supply for custom blade pins?
Drawing with blade width/thickness, shank, length, orientation and tolerances; resin and cycle count help material choice.
