What design guidelines should be considered for the ‘AEP’ and ‘AEB’ versions of DME Accelerated Ejectors?

1. Use the Accelerated Ejector item # AEB-10 for up to 10-7/8 wide X 23-1/2 long mold bases.
2. Use the Accelerated Ejector item # AEB-20 for up to 23-3/4 wide X 35-1/2 long mold bases.
3. Use guided ejection in ejector assembly.
4. Maximum stroke for any unit is 5/8. This provides a 2:1 ratio.
5. Use early ejector return to return ejector assembly.
6. Accelerated ejectors should not be used to overcome springs. Springs may cause the plate to deflect and bind.
7. When using the AEB device, a minimum of four units is required.
8. Lubricate pinion occasionally with a lithium-type grease or oil containing P.T.F.E.
9. AEB and AEP units: Body and Racks are carburized to R/C 45-50.
