Legacy Part Replication

Legacy Part Replication: Bring Discontinued Castings Back to Life

Your equipment is down. The original manufacturer closed decades ago. The part is obsolete, and no one makes it anymore. We do. One Off Casting specializes in replicating legacy metal castings—even when drawings are lost, patterns are destroyed, or suppliers have disappeared. Using reverse engineering, 3D scanning, and patternless casting technology, we reproduce discontinued parts with the precision and material properties of the original.

When you need it

When You Need Legacy Part Replication

Every day without that part costs money. We move fast to get you back online.

Equipment failure — A critical component breaks and production stops
Obsolete parts — The OEM no longer exists or discontinued the part
No documentation — Drawings, specs, or patterns were lost over time
Single-source dependency — Your only supplier can't deliver
Vintage restoration — Historic machinery, vehicles, or equipment need authentic parts
Inventory depletion — Last spare part used, no replacements available

The process

Step-by-Step Process

Assessment & Reverse Engineering
Send us your sample, drawings, or whatever you have. Our engineers analyze the part geometry, identify the alloy, and create a manufacturable 3D model.
Material Matching
We identify the original alloy or recommend an equivalent. Our in-house spectrometer can analyze a sample from your existing part to match chemistry precisely.
Patternless Production
Using robocasting and 3D sand printing, we create molds directly from CAD—no expensive tooling, no 8-week pattern lead time.
Casting & Heat Treatment
We pour your part in the correct alloy with full in-house heat treatment capabilities for aluminum and steel.
Inspection & Verification
Every replicated part undergoes dimensional verification and NDT inspection (LPI/MPI available) to ensure it meets or exceeds original specifications.
Delivery
Parts ship from our Arkansas facility. Rush delivery available for critical situations.

Why One Off

Why Choose One Off Casting for Legacy Parts?

No Minimum Orders

Need just one part? That's our specialty. We're called "One Off" for a reason.

Rapid Turnaround

Patternless casting eliminates weeks of tooling time. Many legacy projects deliver in 2-4 weeks.

In-House Engineering

Our engineers work directly with you—no middlemen, no miscommunication.

Complete Traceability

Full material certifications, heat treatment records, and inspection reports available.

Case example

Case Example: How It Works

The Problem: A food processing plant's 30-year-old filling machine failed. The gearbox housing cracked, and the German OEM had been out of business for 15 years. No drawings existed.

Our Solution: The plant shipped us the broken housing. We 3D-scanned the fragments, reconstructed the CAD model, identified the original alloy (ductile iron 65-45-12), and cast a replacement using 3D sand printing.

The Result: New part delivered in 18 days. Production line back online. Cost was 60% less than a full machine replacement.
