From part design to production

We take your part from DFM review and pattern development through wax sampling, shell building, casting, and final finishing, with each stage building on the last.

01
DFM Review
Reviewing the layout

We review wall thickness, geometry, fillets, gates, and features before pattern development. Required changes are identified to improve castability, pattern manufacture, and final part quality.

Pattern Development
Building the wax pattern

Once the design is approved, we develop the pattern tooling and produce wax patterns representing the final casting geometry. Patterns are inspected before assembly.

Shell Building
Creating the ceramic mold

Wax patterns are assembled into a tree and coated with ceramic slurry and stucco to build a controlled ceramic shell. The shell is dried and prepared for dewaxing and casting.

Casting & Inspection
Producing the first castings

The wax is removed from the ceramic shell, the mold is prepared and heated, and molten stainless steel is poured. The castings are then inspected for dimensions, appearance, and casting quality.

What stainless steel investment casting delivers

Stainless steel investment casting combines complex geometry, fine detail, material flexibility, and near-net-shape production for demanding metal components.

01

Multiple

Stainless Steel Alloys

Select from a broad range of stainless steel grades based on corrosion resistance, strength, temperature, and application requirements.

02

Fine

Part Detail

Investment casting reproduces fine features, intricate profiles, and detailed geometries that can be difficult to machine.

03

Complex

Near-Net Geometries

Complex shapes, undercuts, internal passages, and other difficult features can be produced with reduced machining requirements.

04

Tight

Dimensional Control

The process supports close casting tolerances, with critical features able to be machined when tighter requirements are needed.

05

Smooth

Surface Finish

Investment castings can produce good as-cast surface finish, with additional finishing available for more demanding requirements.

06

Low

Secondary Machining

Near-net-shape geometry can reduce the amount of material removal required on suitable components.

Typical capabilities depend on alloy selection, part geometry, pattern design, shell system, casting conditions, and required tolerances.

Every finish has a purpose.

Stainless steel investment castings can be finished for cleanliness, corrosion resistance, appearance, and surface uniformity. The right treatment depends on the material grade and application.

Cadlete Designs helped me design a 3d model for a quite complex project: the Lightsaber. There were a lot of design decisions which mattered here, and they executed them perfectly! After 3d printing everything worked out well and connected well. The response time is phenomenal, after asking for fixes they were done the next day or even sometimes the same day. They also provided nice explanation videos each time to explain the design choices made. Would definitely recommend!
