Blade Ejectors – Specifics


Blade ejectors are usually modified to suit each particular application. They are manufactured in a variety of methods such as:

  1. Machined from a solid to the desired shape and hardened.
  2. Ground to shape from a through-hardened pin.
  3. Fastened or brazed to a slotted pin.

Tight tolerances must be maintained to prevent the plastic from flashing past the blade ejector into the mold base.
