Industrial Training Report on Production, Quality Control and Maintenance Practices at Sun Engineering

This paper presents a case study framework for studying production, quality control and maintenance activities at Sun Engineering. Production activities such as CNC processing, cutting, bending and fabrication require systematic planning and process control. Quality inspection at incoming, in-process and final stages helps identify defects and maintain product conformity. Maintenance activities, particularly preventive maintenance, help improve machine availability and reduce unexpected production interruptions. The integration of production, quality and maintenance departments is therefore essential for achieving higher productivity, consistent quality, reduced rejection and reliable delivery. A data-driven approach using production output, rejection percentage, machine availability, MTBF and MTTR can further support continuous improvement.
