Peak Stress

ENGINEERING SERVICES

The driving force of my company is a passion for new technologies and finding new solutions for current engineering challenges. Today, this passion drives Peak Stress company, which has evolved from strength calculations for mechanical engineering to an enterprise currently covering a wide spectrum of engineering categories. My company’s activity is based on a modern and optimal network management model “plug & play”. This network is made up of talented engineers representing such fields of engineering as construction, mechanics, energy and fluid mechanics. Using this business model, we can boast the highest quality of our services at low maintenance costs of our design office. Thanks to that my clients pay less for engineering services.

Our Competences

PEAK STRESS offers engineering services in the field of machine and device design and strength calculations. The main branch of our activity are computer simulations using the Finite Element Method (FEM). PEAK STRESS has many years of experience in the dimensioning and optimization of mechanical solutions. Our competences include the construction of large elements, products and machines, as well as complex advanced mechanical solutions in which precision and quality are key parameters.

PEAK STRES has built a network of talented freelance engineers representing such fields of engineering as construction, automation, mechanics, energy and fluid mechanics. Thanks to this network, which currently consists of over 20 members, we carry out multidisciplinary projects. We also work with well-known manufacturers from the chemical, petrochemical and energy industries, and together with our production partners we have the opportunity to install and assemble equipment on site.

MECHANICAL DESIGN

Analysis of factors affecting quality, functionality and price
Machine and product design based on the customer’s specification
Creating new concepts and improving them for new solutions
Optimization of existing solutions
Technical documentation

ENGINEERING CONSULTING

Defining project assumptions and assessments
Creating prototypes of products (3D printing and unit production at our partners)
