The main objective of the project is to research and develop a prototype of a new blowing machine for the production of hollow bodies from plastics up to a volume of about 30 liters. The parameters of the prototype will be characterised by a high degree of novelty in terms of both the design of the machine itself and the extrusion blowing technology. Furthermore, the machine will meet the conditions of reduced energy and material intensity. A brand new machine size range will mean a significant expansion of the range for GDK. The project involves effective cooperation with TUL.
