Streszczenie -W artykule o charakterze literaturowego przegl¹du monograficznego przedstawiono wtryskiwanie precyzyjne jako proces realizowany w uk³adzie roboczym obejmuj¹cym nastêpuj¹ce elementy: cz³owieka-wykonawcê, formê wtryskow¹, wtryskarkê, metodê wtryskiwania, warunki (parametry) wtryskiwania oraz rodzaj wtryskiwanego tworzywa. Szczegó³owo omówiono wp³yw ka¿dego z tych elementów na koñcow¹ jakooeae uzyskiwanych wyprasek i jej powtarzalnooeae, uwzglêd-niaj¹c przy tym strukturê materia³u, w³aoeciwooeci mechaniczne i inne cechy u¿ytkowe, masê, skurcz, stan naprê¿eñ oraz dok³adnooeae wymiarów. S³owa kluczowe: wtryskiwanie, wtryskarki precyzyjne, jakooeae wyprasek, wykonawca, forma wtryskowa, tworzywo przetwarzane, powtarzalnooeae wyników.
SELECTED PROBLEMS OF PRECISION INJECTION MOLDING. PART II. FACTORS INFLUEN-CING THE QUALITY OF PRECISE MOLDINGSSummary -In the literature review the precise injection molding is presented (Fig. 6) as a process realized in a working system consisting of the following elements: man-operator, injection mold ( Fig. 1-3), injection molding machine, injection method, injection parameters (Table 1) and the type of polymer. The effects of all the factors on the final quality of moldings obtained and its repeatability were discussed in detail. The material structure, mechanical properties and other functional features, weight, shrinkage ( Fig. 4 and 5), stress state and accuracy of dimensions of molding were taken into account.
