Selvakumar S

• Professional Summary:

Results-driven manufacturing associate with 15+ years of hands-on expertise in PVC, HIPS extrusion, and precision compressor core component production for high-volume appliance manufacturing.

Excelled in process optimization, defect elimination, manpower utilization, and equipment reliability, achieving up to a 25% scrap reduction and an 18% OEE uplift across multiple lines.

Core Experience & Achievements:

• Extrusion Production Expertise (11+ Years): Maintaining and monitoring daily operations on PVC and HIPS extrusion lines for refrigerator gaskets, sheets, and glass shelf trim parts, optimizing parameters (melt temperature, screw speed, die calibration) to achieve a 98% first-pass yield, and reduce changeover time by 30%.
• Implemented lean improvements, including 5S and SMED, resulting in a 20% productivity increase, a 15% scrap reduction, and sustained OEE above 85% across 3-shift operations.
• Led troubleshooting of extrusion defects (e.g., die swell, melt fracture), utilizing root-cause analysis (5-Why, fishbone diagrams) to eliminate recurring issues and stabilize output at 1,200 kg/hour.
• Compressor Core Parts Manufacturing (4+ Years): Oversaw precision machining and assembly of cylinder blocks, crankshafts, and pistons, ensuring tolerances within ±0.005 mm via SPM machines, such as honing, boring, reaming, centerless grinding, cylindrical grinding, super finishing, and Mn Phosphating operations.
• Drove quality enhancements post-training, reducing piston-cylinder clearance defects by 15% through optimized coolant systems, and tool geometry adjustments.
• Supported high-volume production ramp-up, achieving 95% on-time delivery for 400,000 * 3 (cylinder blocks, piston, crank shaft) + units/month while maintaining SPC-compliant process capability (CpK > 1.33).

International Training & Recognition:

• Handpicked for advanced compressor manufacturing training at Samsung’s Gwangju, South Korea, plant, mastering machining processes from raw material to sub assembly processes for reciprocating compressors.
• Successfully transferred acquired expertise to the domestic facility, accelerating line readiness by 40%, and earning a formal award from the Samsung South West Asia CEO for leadership, technical proficiency, and exceptional performance in greenfield plant commissioning and knowledge transfer.
