Custom One-Off Castings for Industrial & Engineering Applications
Precision. Speed. Reliability.
At One Off Castings, we specialize in custom, one-off and low-volume metal castings for manufacturers, engineers, and project teams who need exactly one part — done right.
Whether you’re replacing a discontinued component, prototyping a new design, or solving a complex manufacturing problem, we deliver engineered castings without the delays, minimum orders, or guesswork of traditional foundries.
What Is a One-Off Casting?
A one-off casting is a custom metal casting produced as a single unit or small batch, often for:
Replacement parts
Prototypes
Legacy equipment
Specialty or non-standard designs
Unlike high-volume foundries, we are built for flexibility, not mass production.
Industries We Serve
We support customers across a wide range of industrial sectors, including:
Manufacturing & Fabrication
Mining & Aggregates
Agriculture & Heavy Equipment
Energy & Utilities
Construction & Infrastructure
Maintenance & Repair Operations (MRO)
If downtime is expensive, we’re built for your use case.

Frequently Asked Questions
Do you really do single-part castings?
Yes. One-off and low-volume castings are our specialty.
What files do you need to quote a part?
Drawings (PDF, STEP, DXF), photos, or physical samples all work.
What is your typical lead time?
Lead times vary by material and complexity, but we prioritize speed without sacrificing quality.
Can you reverse-engineer an existing part?
Absolutely. Reverse engineering is a common request.
Do you work with discontinued or obsolete components?
Yes — this is one of our most common project types.
