RISK ASSESSMENT OF THE TIRE VULCANIZATION PROCESS USING THE FMEA METHOD

The application of FMEA method (DFMEA and PFMEA) is mandatory according to the requirements of the international standard IATF 16949. The article shows the possibility of applying the method of analyzing the types and consequences of process failures (PFMEA) according to the FMEA Handbook, which is a new reference manual. The new FMEA methodology is described as a process with seven steps/stages organized into three phases. The application of the FMEA method (Handbook) is considered for risk assessment of the process “Tire Vulcanization”, which is one of the hazardous processes in tire manufacturing due to the presence of a number of risk factors such as: use of high temperatures and pressures; working with large equipment that increases the risk of injuries and accidents; use of hazardous materials. An algorithm for conducting PFMEA, an algorithm for the process of “Tire Vulcanization” is presented. The main risks of this process, their causes, consequences are determined. Analysis of failures of the process “Vulcanization of tires” in accordance with FMEA (Handbook) is carried out. Categories of priority of actions for PFMEA are considered. Action priority zones for each of the identified risks according to the risk matrices are determined. A table of PFMEA results for the Tire Vulcanization process in accordance with the FMEA Handbook is presented. Medium and high priority risks are identified.
