Why 100% Unitary Control Is a Must in Critical Applications

Can your application tolerate a single defective component?

In sectors such as medical devices, automotive safety, or aerospace, the answer is simple: not. That’s why at RPK Group, we’ve made 100% unitary control a core part of our production philosophy.

We work with extremely narrow tolerances, designing and manufacturing components where precision, safety, and repeatability are vital. But process capability is not always enough—especially when the risk of failure directly impacts human lives.

To meet these demands, we develop and manufacture our own high-performance control machines in-house. This gives us complete control over inspection processes, allowing us to design solutions that are specifically tailored to the component and the application.

Our systems include:

✅ 100% Free Length (L₀) control

✅ 100% Free Angle (α₀) control

✅ Load testing

✅ Electric resistance measurements

✅ Geometrical and visual inspection with integrated vision systems

These machines are seamlessly integrated into our production lines to ensure that every part that leaves our facilities meets the drawing’s key requirements—without exception.

We don’t just talk about quality. We engineer it into every step.

Here’s an example of one of our latest complex unitary control systems for critical assembly.
