Abstract

The publication deals with an innovative technology called powder-based metal injection moulding, which is a combination of traditional polymer injection moulding and powder metallurgy. With the technology, it is possible to produce metal components with complex geometry in large series. There is an extremely large selection of materials that can be used, mostly steel, copper, titanium or nickel-based alloys. In this research, the material used is type 17-4PH, martensitic corrosion-resistant steel, and since it is a widely used material, it is examined in many international articles and research studies, and it is also common in industry, so it is advisable to use this type of material for further comparability. Little information can be found in the literature about spraying parameters and their effects, which is why this research focusses on this. On the other hand, these data can also serve as useful information for the industry. During the production of so-called green products, the effects of product shrinkage were measured by changing the most important parameters and comparing the effects of these parameters to traditional polymer injection moulding.
