ADDITIVE
MANUFACTURING
We have rich experience with additive technologies for printing polymers, metal materials and special materials such as wax or sand. We actively collaborate with academia and industrial partners on research into new approaches and materials, especially in the field of metal 3D printing.
- We can help you choose the right additive technology
- We evaluate the effectiveness of the use of additive technology vs. traditional production technology in terms of time, quality and price
- We modify the design of your parts taking into account the possibilities of the given additive technology
- We ensure production with a wide range of additive technologies and materials.
- We organize educational workshops where even your company can enter the world of additive technologies
CASE STUDY
APPLICATION OF ADDITIVELY MANUFACTURED
STRUCTURES IN HEAT EXCHANGERS
- Additive manufacturing enables the production of mathematically defined TPMS (Triply Periodic Minimal Surface) structures, which are more efficient than conformal or conventional cooling
- We developed our own algorithm that is able to generate structures depending on the heat transfer simulation
- The heat exchange takes place in a controlled manner and takes into account areas with uneven heat load
- The application was verified in foundry moulds for high-pressure die casting of aluminum or zinc alloys
- Development and application of printed structures focused on heat transfer in cooperation with the Institute of Physics of the Czech Academy of Sciences and Beneš a Lát, a.s.

FOUNDRY MOULD
- A combination of topological optimisation, conformal cooling and additive manufacturing technology
- Conformal cooling copies the complex shape of the casting to the maximum
- Topological optimisation performed to reduce additive manufacturing costs
- Half of the mould is manufactured additively, and the core is made by hybrid printing on a pre-machined semi-finished product to save costs
- Better cooling results in a shorter cycle time

OPTIMISATION
& DIGITISATION
We offer diverse support in the field of digitisation, as we have broad knowledge of technologies, software tools and procedures, and we follow modern trends in industrial practice and news on the market. We can design and assess specific solutions for a company or their operational parts. In digitisation we offer:
- A digital audit
- A digitisation strategy proposal
- Consultation in choosing an IS
- A technological audit
- Simulation of production and technological processes
CASE STUDY
DIGITISATION STRATEGY
AT PRESTAR
- The goal was to design a digitisation strategy for the next seven years
- Through joint workshops, we analysed key processes from the acceptance of an order, through its implementation, to the delivery of the product to the customer
- A mind map of activities was created and divided into logical units
- A schedule with individual activities, cost estimates, supplier recommendations and a detailed description of activities was prepared
- The developed strategy supported and initiated concrete steps that help in the company’s development
FEASIBILITY STUDY – AUTOMATION OF THE GRINDING
AND POLISHING PROCESS AT PROSPON
- Request to turn manual processing into an automated process
- Complicated search for cost-effective technology due to a small production volume and a large variety of parts
- All relevant technologies were assessed, including the robotic station that the client was considering
- Various aspects of the considered technologies were evaluated – variability, process time, productivity, investment costs, rate of return, output quality, difficulty of production preparation, etc.
- Tumbling technology with great potential to meet customer requirements was recommended
COORDINATION OF ERP SELECTION FOR COMPANIES
CZ-AUTO SYSTEMS AND CZ-SKD SOLUTIONS
- The two companies agreed on a coordinated procedure for choosing an ERP solution
- The goal was to find a suitable solution for different companies (a small company with custom production and a medium-sized company with different types of production)
- Together we put together the project team and the requirements for the ERP system
- Recommendation of suitable solutions according to specified conditions, organization of the tendering process and development of a tender evaluation system
