Risk Analysis of Component Quality in the Production Process of Gate Valves Using the Failure Mode and Effect Analysis Method

Material damage is a common occurrence in every production in a company, of course material damage is very often found in the Quality Control process in every manufacturing company. Especially in the company I do internship there are four production production sections in the burr and stamp process, namely: structure division, finishing division, assembly division, packaging division. The one that often experiences damage problems in the burr and stamp process is the structure division and can still be reworked depending on the level of material damage, based on the largest percentage of products that are most hampered are in the process of stamping material identity details with stamping machines and stamping several material letters without stamp machines, namely by manual tapping or carving processes. The company wants to reduce the addition of rework that makes delivery to customers delayed and not according to shipping estimates. Therefore, the Failure Mode and Effect Analysis (FMEA) method will be used. The stages carried out using the FMEA method are identifying failure modes, identifying the effects of failure, identifying cause effects, determining severity rating values, occurrence rating values, determining current control, detection values, and calculating the Risk Priority Number (RPN) to determine the cause of the damage problem
