Injection Molds for Morgan Presses

Delphi O.E.M. Co. designs and builds injection molds primarily for Morgan injection molding machines. Our experience includes roughly 100 molds made for our own molding work as well as custom molds made for others.

That work has ranged from very simple molds that are placed in the machine and opened by hand to self-opening molds using ejector pins, stripper mechanisms, removable inserts, cam slides, and other specialized details.

We are also developing a series of practical Morgan mold-plan packages for people who want to machine and build their own molds.

Three Ways We Can Help

Morgan Mold Plans

Dimensioned drawing packages for proven mold constructions that can be machined by the purchaser. The first plans are now being prepared.

Custom Mold Design

Have a part that needs a mold? We can develop the mold arrangement around the part, the material, the required ejection method, and the Morgan press.

Complete Mold Making

Delphi can also machine and build the mold rather than supplying drawings alone. Prototype and short-run molding can be discussed as part of the job.

Mold Construction Types

These are some of the mold arrangements we have used. They also form a useful progression for the Morgan mold-plan series.

Hand placed / hand opened. The simplest arrangement: the mold is placed in the press by hand and pried open after molding.
Self opening. The mold is arranged so opening of the press separates the mold automatically.
Knockout / ejector pins. Pins push the molded part from the cavity or core after the mold opens.
Stripper plate. A moving plate strips the molded part from a core or other forming surface.
Loose or threaded inserts. Inserts come out with the molded part and are removed from the part by hand afterward.
Cam slide plates / side action. Slides withdraw side features or undercuts that prevent straight opening.
Stripper-ring core insert. A turned core/insert assembly uses a localized moving ring or sleeve to strip the molded part from the forming section.

Morgan mold plans are being developed now. If there is a particular mold construction you need, contact Delphi O.E.M. and tell us about the part and the Morgan machine you are using.

Morgan G-100T in Our Shop

Delphi operates a Morgan G-100T injection molding machine. Our mold work is therefore based on actual setup, molding, opening, ejection, and troubleshooting experience on the machine—not only on drawing-board dimensions. See our equipment and capabilities.
