Single Part vs. Series: At What Quantity Does Series Production Pay Off?

SI

Strobel Industry

Published on 24 February 2026

The most common question from our customers: "Why is the single part so expensive?" The answer lies in the cost structure of CNC manufacturing. One-time costs like programming and setup are incurred regardless of quantity – and that makes all the difference.

Cost Example: A Typical Turned Part

The Sweet Spot: 5-500 Pieces

At Strobel Industry, the sweet spot for small series is 5-500 pieces. In this range, unit costs drop dramatically without committing to large series of 10,000+ pieces.

Prototype → Pre-series → Series

Our approach: Start with 2-5 prototypes for functional testing. If approved, we produce a pre-series (20-50 pieces) for process validation. Only then do we move to series production – with optimized programs and minimal unit costs.

Frequently Asked Questions

Why are single CNC parts so expensive?

A single part bears 100% of fixed costs: CAM programming (~€120) and machine setup (~€80) are charged to one piece. At 100 pieces, these €200 spread across all parts – just €2 per piece.

At what quantity does CNC series production pay off?

From 5 pieces, unit costs drop 80%+. The sweet spot is 5-500 pieces. Important: material selection also strongly affects pricing.

What is a framework agreement for CNC parts?

A framework agreement sets an annual total quantity that you call off flexibly in partial batches. Programming costs are incurred only once. Tips on optimal ordering here.
