Your Investment Casting Process in 8 Stages
Ceramic shell investment casting forms metal around a sacrificial pattern. Wax is removed before pouring; the shell is broken away after solidification. This is not high-pressure die casting.
Wax Patterns
Create the sacrificial pattern
Tree Assembly
Arrange patterns and feed paths
Shell Build
Coat and dry the ceramic shell
Dewax & Fire
Remove wax and prepare the shell
Pour & Solidify
Fill the shell with molten alloy
Shell Removal & Cut-Off
Remove shell and separate castings
Treat & Machine*
Complete agreed secondary operations
Inspect & Release
Check the specified final state
*Heat treatment and machining only when specified. These stages explain the route, not a promised schedule.
Know What Is Reused — and What Repeats
Separate investment casting tooling cost from recurring wax, shell and production work.
Reusable tooling
Wax-pattern die and agreed fixtures. Confirm ownership, storage, maintenance and revisions.
Recurring production
Wax patterns, ceramic shells and casting operations. The reusable wax die is not the metal-pouring mold.
ILLUSTRATIVE PLANNING EXAMPLE — NOT CAPACITY OR AN ORDER MINIMUM
8 patterns / tree × 25 trees = 200 planned castings
Before losses. This is not an approved tree layout or yield guarantee. Trials, rejects and inspection samples can change required quantities.

Review scope by feature
Cast & trim→Heat treat*→Finish machine→Inspect
No universal machining allowance is assumed.
| Your input | Finished drawing, datums and delivery state |

|---|---|
| Our review | Cast texture, cut-off zones and permitted repair |
Final placement and finishing scope are agreed for your project.
3 Part States. One Controlled Acceptance Plan.
Define investment casting tolerances by feature and inspection stage — not one number for the whole part.
| State | What to identify | Acceptance basis |
|---|---|---|
| As-cast | Cast geometry, core location and machining stock | Casting drawing and datum scheme |
| After heat treatment* | Condition, distortion and remaining stock | Specified condition and agreed checks |
| Finish-machined | Bores, threads, seal faces and mating datums | Final drawing and measurement method |
*Only when required. Casting machining allowance is reviewed for your grade, geometry and datum plan.

Verify Your Final Mating Features
Review final bores, threads, seal faces and datums in the agreed delivery state.

Answers Before You Commit
Explore Other Casting Routes →Which features should be cast and which should be machined?
Near-net shape does not mean every feature is finished. Mark critical bores, threads, datums and sealing faces. Review machining stock and inspection stages before tooling.
Does lost wax casting mean no parting or gate marks?
No. Wax-pattern tooling can leave split lines, and tree attachment creates gate-contact zones. Agree removal locations, blending and appearance limits on your drawing.
What determines investment casting surface finish?
Your alloy, pattern quality, shell system, casting geometry and finishing route affect the surface. Define appearance zones and an approved sample rather than assuming one universal finish.
Can you use an existing wax-pattern tool?
Share the tool drawings, condition, ownership terms and prior process records. Compatibility and any modifications must be reviewed before transfer or repeat production.
Investment casting vs die casting: which fits my part?
Compare alloy, geometry, cast and machined interfaces, tooling investment and demand. Investment casting uses a sacrificial pattern and ceramic shell; pressure die casting uses a reusable metal die.
What affects minimum quantity and lead time?
Tooling, pattern and shell work, alloy batch planning, secondary operations and inspection scope affect feasibility and scheduling. Request a project-specific quantity and schedule; no universal minimum or lead time is promised.
