- Sucker or Puller bushing made from H-13 50-52 Rc, M-2 58-60 Rc, S-7 54-56 Rc, 420SS 52-54 Rc or A10 58-60 Rc
-
- This bushing is used as a wear component for plastic injection mold. Runner pins, puller pins or sucker pins are used to grip runners to ejector side of mold. They can also be modified and used as a small cavity inserts with ejector pin or core pin to fit.
-
- A standard off-the-shelf H13 Nitrided core pin was used as a puller or runner pin to fit the above bushing.
- This choice may hold down cost at mold start-up but the rapid wear on the exposed soft core assures early mold repair.
- Choosing M-2 or A-2 60-62 Rc will last longer and extend runtimes before normal mold repair.
The prints below were used at CPS Mfg.
before the company was closed and merged into Matthews Gauge operations.
I will be updating the information on the
print as time permits.
