• Optimize cycle times, reduce scrap, and improve OEE
• Troubleshoot molding issues including:
• Flash
• Short shots
• Cure variations
• Knit lines
• Voids
• Dimensional variation
• Establish standardized process parameters and work instructions
• Lead root cause investigations using 5 Why, 8D, Fishbone, and other problem-solving tools
• Support new product launches, mold qualifications, and production transfers
• Partner with Tooling, Production, Quality, Maintenance, and NPI teams
• Drive continuous improvement through Lean, Kaizen, SPC, and data analysis
