Machining a mold detailAll mold making projects require design, steel preparation, rough machining, precision machining, fitting and mold sampling.

Precision Machining

Gear mold insertsToday’s precision machining relies on three primary technologies for a superior product:

  • Computer Aided Design (CAD),
  • Computer Aided Manufacturing (CAM), and
  • Computer Numerical Control (CNC).

These technologies interface with various types of precision machining equipment such as hard milling centers, graphite machining, and electrical discharge machining (EDM).​

At Prodigy Mold & Tool, our hard milling center allows mold components to be machined in the hardened state. In many cases, this can eliminate secondary machining steps, saving time and money.

Electrical Discharge Machining (EDM)

EDM removes material from the mold by a series of rapidly recurring electrical discharges between electrode and workpiece. This process is used when working with hard metals, or when trying to create complex geometries that are difficult to produce using more traditional machining processes.

The two primary types of EDM are Sinker EDM and Wire EDM, both of which are used by the expert machinists at Prodigy.

With sinker EDM, an electrode (usually made of carbon) and the mold are placed in an insulating liquid. A current is rapidly passed between the electrode and the mold, discharging a small amount of material from both the electrode and the mold. Varying the strength and duration of the electrical current will remove more or less material from the mold. The mold geometry can be controlled precisely, creating complex three-dimensional shapes.

In wire EDM, a thin brass wire is fed from a spool across the mold. Rapid electrical discharges between the wire and the mold remove material from the mold. Wire EDM is typically used to cut plates as thick as 300mm and to make punches, tools, and dies from hard metals. The upper guide can also move independently, creating the capability to cut tapered and transitioning shapes.

Once the mold has been precision machined, it’s finely polished to remove all machining and grinding marks. This process ensures that we deliver a superior tool--one that meets exacting design specifications for both fit and texture.

Our injection mold sampling process examines and corrects any issues that could affect the moldability of a part. Adjustments are made quickly and efficiently, to ensure that your injection mold is delivered ready to run.
