Work History

Product and Extrusion Specialist

Goodyear Tire & Rubber
05.2024 - Current
  • Analysed daily performance data (MII) to identify inefficiencies, machine downtime, and drive corrective actions.
  • Led and managed the die shop, overseeing a team of two die makers to ensure optimal machine time utilization and timely completion of die trials.
  • Prioritised daily production based on Kanban system and real-time inventory checks to minimise delays.
  • Conducted water quality testing (microbial load, phosphate, hardness) and introduced the Hash turbidimeter to cut cycle time in half.
  • Detected measurement discrepancies in phosphate meters, leading to process improvements.
  • Monitored line speed of 3 extrusion lines (6", 8x8, Quad) bi-weekly to reduce product variation.
  • Used inline scanner (Dr. Noll) data to evaluate machine performance; calculated CP & CPK via JASP software.
  • Verified monthly shrinkage and split tests for die makers to ensure tooling quality.
  • Facilitated daily meetings with internal stakeholders (Mixing, Final Finish, NPI) to align compound specs, address defects, and adjust production plans.
  • Attended DMS meetings to align with broader business strategy and production continuity.
  • Implemented and standardized lean practices to improve workspace efficiency, safety, and operator mobility.
  • Led two Standard Kaizen problem-solving initiatives: 1. Lack of sidewalls on building machines 2. Inconsistent supply of filter paper.
  • Applied 'Three-Legged 5M Fishbone' methodology for root cause analysis.
  • Used Catia to design splice bars and GADAM CNC for manufacturing components.
  • Implemented a Turbidimeter System to streamline the water filtration process,
    significantly reducing downtime and enhancing quality water availability. - Led project oversight, including planning, implementation, and training of lab
    technicians and extrusion team on new equipment and processes.
  • Monitored and analysed extruder performance through Grafana, identifying variances, tracking machine performance, and optimising processes to
    improve efficiency and reduce defects.

Final Assembler

Shatterproof
