Abstract


The study examines the financial and technological possibilities of a start-up business company, which creates boutique concrete elements (in ancient styles such as Renaissance, Baroque, and Gothic) with an optimal budget for the activity. The main problem is the extremely high cost of the matrices, which until now have been made of silicone and polyester resin. The investment for each mold is substantial and this changes the price of the final product. The present study shows the application of a PVC blister packaging machine in producing decorative concrete elements, using the vacuum forming method. The technological time and the value of the matrix have been optimized several times, showing the methodology's effectiveness and the way of working.
