Why the right process choice matters
The manufacturing process affects:
- unit cost,
- dimensional consistency,
- speed to scale,
- and design constraints.
Casting (investment casting) — quick overview
When it typically fits
- Organic, volumetric geometry.
- Designs with details integrated into the body.
- Runs where design flexibility is valuable.
What to watch
- Tolerances and very thin/delicate areas.
- Dimensional control in critical points.
- Designing to avoid deformation and rework.
Stamping (die striking / stamping) — quick overview
When it typically fits
- Flat or repeatable geometries.
- Components that benefit from high consistency.
- Production with stable volume.
What to watch
- Tooling/jigs (upfront investment).
- Design changes are typically costlier once tooling is set.
- Geometry limitations depending on the piece.
Fast comparison
- Design flexibility: casting is often more flexible.
- Large-scale consistency: stamping can be superior for suitable parts.
- Upfront tooling: stamping often requires more preparation.
- Iteration (changes): casting is typically easier to iterate.
How to decide (key questions)
- Is the piece suitable for repeatable, controllable geometry?
- Are you producing sustained volume or validating demand?
- Do you expect frequent design changes?
- What matters most: unit cost, speed, or aesthetic freedom?
What we need to recommend safely
- CAD/key dimensions or a dimensioned sketch
- Material and finish
- Target quantity and forecast
- Critical areas (setting, clasp, tolerances)
