Celem badań była ocena wpływu poroforów fizycznych i chemicznych na właściwości jakości powierzchni i mechaniczne estetycznych wyprasek wtryskowych dla przemysłu samochodowego. Badania wykonano przy użyciu formy typu core-back pozwalającej na wykonanie wyprasek wtryskowych o grubości do 4 mm. W badaniach oceniono wpływ zawartości poroforu na strukturę wyprasek oraz odporność na test upadającej kulki. Wykazano znaczące zmniejszenie masy i gęstości wyprasek wtryskowych z poroforem, co może przyczynić się do obniżenia zużycia surowca, a tym samym mieć pozytywny aspekt ekologiczny i ekonomiczny. Otrzymana struktura porowata dzięki technologii formowania core-back charakteryzowała się jednolitą wielkością i rozmieszczeniem porów w rdzeniu wypraski wtryskowej. Wykazano również znaczące zmniejszenie odporności udarnościowej wyprasek porowatych oraz znaczący spadek ich walorów estetycznych

The aim of the research was to assess the impact of physical and chemical blowing agents on the surface quality and mechanical properties of aesthetic injection moulded parts for the automotive industry. The tests were carried out using a core-back type mold that allows the production of injection moulded parts with a thickness of up to 4 mm. The tests evaluated the impact of the blowing agent content on the structure of the moulded parts and the resistance to the falling ball test. A significant decrease in the weight and density of injection moulded parts with a blowing agent was demonstrated, which may contribute to the reduction of raw material consumption and thus positive ecological and economic aspects of the method used. The obtained porous structure, due to the core-back moulding technology, was characterized by a uniform size and distribution of pores in the core of the injection moulding. A significant decrease in the impact resistance of porous moulded parts and a significant decrease in their aesthetic values were also demonstrated.
