Job Overview

• Set up, start up, and optimize injection molding machines and auxiliary equipment
• Develop, adjust, and maintain molding processes to meet quality, cycle time, and scrap targets
• Troubleshoot and resolve complex molding defects (e.g., short shots, flash, warpage, splay, burn marks)
• Analyze recurring process issues and implement corrective actions to improve consistency and efficiency
• Modify and adapt processing parameters, tooling, materials, and equipment to resolve production challenges
• Perform mold validations, process studies, and parameter optimization (scientific molding principles preferred)
• Interpret part quality data and make process adjustments based on root cause analysis
• Work with engineering and quality teams to support new product launches and process development
• Ensure adherence to safety, quality, and production standards

Job Requirements

• Train and mentor operators and junior technicians on proper processing techniques and troubleshooting methods
• Serve as a hands-on technical resource for complex molding or equipment issues
• Provide guidance on best practices for material handling, drying, and processing conditions
• Support continuous improvement initiatives including cycle time reduction, scrap reduction, and uptime improvement
