Manufacturing Custom Plastic Molds

Building custom plastic injection molds involves two primary machining methods: Electrical Discharge Machining (EDM) and Computer Numerical Control (CNC) machining. Each method is essential for creating precise mold components that meet complex design specifications.

EDM Machining

EDM uses a copper or graphite electrode to burn the mold shape into the component. This process is ideal for intricate details like sharp corners or thin ribs that cannot be easily cut with CNC. While slower and more expensive, EDM provides unmatched precision for complex mold features. The steps include:

  1. CNC machining electrodes from copper or graphite.
  2. Submerging both the electrode and mold in dielectric fluid.
  3. Using an EDM machine to discharge electricity at a controlled rate to erode the mold material into the required shape.

CNC Machining

CNC machining utilizes computer-controlled technology to cut precise geometries from raw metal blocks. Designers create 3D CAD models that define the mold’s dimensions, which are then converted into CAM software instructions. The CNC machine follows these instructions to cut the mold with high speed and efficiency. CNC machining is faster and more cost-effective for producing large, less intricate features of the mold.

The combination of EDM for detailed features and CNC for broader shapes ensures high-quality, durable molds capable of producing complex plastic parts.
