Custom Mold Minimum 
Due to the time and precision involved in designing and machining custom molds, all custom projects require a minimum order of $200.

If your project is smaller, we’d be happy to recommend one of our standard molds or suggest adjustments to meet your budget.

How Our Custom Graphite Mold Process Works

We specialize in designing and machining custom graphite molds for metal casting and related high-temperature applications. To ensure accuracy and performance, we follow a structured process from concept to finished mold.

Step 1 — Customer Design Submission

To begin a custom mold project, we require one or more of the following:

Accepted Design Inputs

  • Hand drawings (clear and legible)

  • Fully dimensioned sketches

  • 3D CAD files

    • STL (preferred)

    • STEP / STP

    • 3DM

STL files are preferred as they allow the fastest turnaround.

If submitting hand drawings, please include:

  • Overall dimensions

  • Cavity depth

  • Draft angles (if known)

  • Any critical tolerances

  • Intended metal type (silver, gold, bronze, etc.)

Step 2 — Model Creation or Refinement

If a usable 3D model is not provided, we can create one based on your drawings or concept.

  • We generate a manufacturable 3D model

  • Geometry is optimized for graphite machining

  • Draft, fillets, and relief are added as needed

Design Adjustments

At this stage, the model can be modified to your specifications, including:

  • Size changes

  • Text or logo adjustments

  • Depth or volume changes

  • Edge radii or surface detail updates

Step 3 — Model Approval

Once the 3D model is complete, we will send a visual preview (and/or STL file) for review.

Customer Confirmation Required

Production does not begin until:

  • The customer confirms the model is correct

  • All dimensions and features are approved

Any changes requested after approval may result in additional charges or lead time adjustments.

Step 4 — Machining the Graphite Mold

After approval:

  • The mold is CNC-machined from high-quality graphite

  • Machining is optimized for surface finish and durability

  • Cavities are cleaned and inspected before shipment

Each mold is produced specifically for your approved design.

Step 5 — Final Inspection & Shipping

Before shipment:

  • Dimensions and features are visually inspected

  • Cavities are cleaned of graphite dust

  • Mold is packaged to prevent damage during transit

Shipping details and tracking information are provided once the mold ships.

Important Notes
  • Graphite molds are designed for experienced users

  • Mold performance depends on material, temperature, and technique

  • Minor surface variations are normal due to graphite’s natural structure
