Manufacturing Reassurance
We manufacture precision stainless steel and alloy castings with tight dimensional control for critical industrial applications.
Achievable Tolerances
Precision Castings Built to Engineering Specification
Our process control, tooling design, and measurement systems allow us to consistently achieve:
Linear tolerances
±0.005–0.010 inch (±0.13–0.25 mm)
Hole/ID tolerances
±0.004–0.008 inch (±0.10–0.20 mm)
Flatness & straightness
<0.010 inch per 100 mm
Surface finish
up to Ra 3.2–6.3 μm as-cast (finer with post-processing)
Actual tolerance capability depends on:
-
Alloy selection
-
Section thickness
-
Tooling and gating design
-
CMM measurement requirements
-
Machining allowance (if required)
If you need tolerance confirmation, upload your CAD our engineers provide a free DFM + tolerance feasibility check.
