TY - JOUR N2 - In this work, the influence of plastic injection molding conditions, mainly plasticizing conditions: plasticizing pressure (back pressure) and decompression (suck-back) after dosing on weight, thickness, mechanical properties and structure of HDPE parts obtained by injection molding with the addition of chemical blowing agent was done. In order to enable the manufacturing of correctly made molded parts under given plasticizing conditions, other parameters (hold time and hold pressure, injection velocity and injection time) were also changed. It was found that making correct molded parts using decompression requires increased hold pressure and hold time. The share of the porous structure in the parts is inversely proportional to the decompression as well as the hold pressure and hold time, while the plasticizing pressure has little effect on thickness, mass, tensile strength and elongation at maximum force, however, it affects the structure of the molded parts to some extent.
