Spiring - Pirnar&Savšek d.o.o.

Since 1987, we have worked at consulting and executable engineering in the field of mechanical engineering.


Spiring - Pirnar&Savšek d.o.o.

A journey through the last three decades evokes at least some sentimentality even with those devoted to the less romantic technical science. For us, it is a period too short to call ourselves "veterans", but nevertheless long enough to believe that an objective bystander could think of us in terms like "maturity" and "experience". (by Zdenko Savšek and Miro Pirnar the founders of the engineering bureau in our book Mechanical engineering with head and heart)


Development of new machines and consulting

Along with good theoretical knowledge in mechanical engineering our engineers are highly qualified for working with software packages ANSYS, PRO/E, Solid Works, and AutoCAD. All the above-mentioned qualities are effectively used in the development of new products, machines, and appliances.

FEM analysis

Finite element method (FEM) analysis

FEM is a numerical method used for the prediction of how a part or assembly behaves under given conditions. We use Ansys software for solving structural, heat transfer and fluid flow problems.

Strain Gauges

Strain gauges measurements

A combination of analytical and experimental techniques and procedures goes hand in hand. What we calculate analytically we often confirm by doing some measurements. On the other hand, when we don't know what to use as loading conditions in our analytical model we firstly do measurements and later analyze what will happen with the structure below real loadings.

Mobile robot

Current projects

A consortium of companies TEGRAD d.o.o., PIRNAR & SAVŠEK d.o.o. and KOVINC d.o.o. will develop and launch a comprehensive digitized solution for automatic hole drilling. The project duration is from December 2023 to November 2025.
