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

In the article enterpris e acting in the business of processing plastics was researched . In the enterprise is realizes mainly mass pr o- duction. The main factor that decides about the reliability of applied technologies there are used machines. As a result of analysis a modern i- ty level of sub - assemblies for two machines was determined (injections moulding machine and extrusion machine). A nalysis of the machines ef fective ness based on chosen TPM coefficients was also undertaken . It allowed the assessment of the working time of these machines.
