Analysis of the modernity and effectiveness of chosen machines in the processing of high-molecular materials

In the article enterprise acting in the business of processing plastics was researched. In the enterprise is realizes mainly mass production. The main factor that decides about the reliability of applied technologies there are used machines. As a result of analysis a modernity level of sub-assemblies for two machines was determined (injections moulding machine and extrusion machine). Analysis of the machines effectiveness based on chosen TPM coefficients was also undertaken. It allowed the assessment of the working time of these machines.
