Low Volume Production

At One Off Castings, we specialize in low-volume metal casting for prototypes, specialty components, and legacy parts. Our fully in-house process — from engineering and mold-making to pouring and machining — allows us to deliver fast, precise, and consistent results without the delays and inconsistencies of outsourcing.

Why Choose Low-Volume Production?

Not every job needs thousands of parts. For teams developing new products, testing fit and function, or replacing hard-to-source components, low-volume casting offers flexibility without compromising quality or efficiency.

Whether you're building a one-off prototype, servicing an older system, or filling a short-run order, our process gives you:

  • Speed to market

  • Tight quality control

  • Flexibility to iterate

  • Cost-effective production at any scale

Our Advantages: Why We're Different

Fully In-House Production
We handle every step — engineering, Robocasting, mold creation, pouring, machining, and inspection — all under one roof. This ensures:

  • Faster lead times

  • Real-time design updates

  • Direct communication with our engineering team

✔ Patternless Robocasting for Agility
Our robotic mold-making enables quick-turn production without the cost or lead time associated with traditional patterns — ideal for prototypes or designs that frequently change.

✔ Engineering-Driven Approach
We work directly with your team to evaluate specifications and ensure manufacturability — no guesswork, no generic templates, just tailored engineering support for your project needs.

Our Low-Volume Process

Engineering & Design Review
We collaborate with your team to define the part’s purpose and tolerances.

Mold Creation – Traditional or Robotic
Depending on the design and delivery needs, we select the right tooling method — from traditional sand molds to advanced Robocasting.

In-House Pouring & Machining
All casting and finishing are performed in-house, using alloys like aluminum, bronze, and ductile iron.

Quality Assurance
The first part is laser scanned and measured for accuracy. Subsequent parts undergo thorough visual inspection to ensure consistent, production-ready quality.

When to Choose Low-Volume Production

  • Prototypes – Validate design and performance in real-world conditions

  • Small-Batch Orders – Fulfill limited-run product needs or initial launches

  • Legacy or Custom Parts – Replace discontinued or hard-to-source components

  • R&D and Field Testing – Produce working versions for early trials and evaluation

Benefits of Low Volume Production with One-Off Casting

  • Speed to Market
    No middlemen. Just streamlined, focused production that gets your part built faster.

  • Cost Efficiency
    Save by skipping the overhead of tooling up for mass production or managing multiple vendors.

  • Flexibility
    One-off? Prototype? Legacy part? We’re built to adapt.

  • Consistency
    Our fully integrated process ensures every part is cast, machined, and inspected with the same precision and care.
