Core Responsibilities

Primary Functions

Team Leadership & Development: Directly supervise a team of molding technicians, process engineers, material handlers, and operators, managing scheduling, performance evaluations, and disciplinary actions to foster a high-performance work environment.
Production Schedule Attainment: Drive the execution of the daily production schedule, ensuring all molding machines are operating efficiently to meet output targets, order deadlines, and customer requirements.
Process Optimization & Control: Champion the use of scientific and decoupled molding principles to troubleshoot, optimize, and stabilize injection molding processes, aiming to improve cycle times, reduce scrap, and enhance part quality.
Quality Assurance & Compliance: Uphold stringent quality standards by ensuring all personnel adhere to work instructions, quality inspection procedures, and documentation requirements; actively participate in root cause analysis for any quality deviations.
Safety & Environmental Stewardship: Enforce all safety protocols, including Lockout/Tagout (LOTO), machine guarding, and proper use of Personal Protective Equipment (PPE), to maintain a zero-incident workplace and ensure compliance with OSHA and environmental regulations.
Mold Change & Setup Efficiency: Oversee and coordinate all mold changeovers and machine startups, focusing on minimizing downtime through Single-Minute Exchange of Die (SMED) techniques and ensuring first-piece approval procedures are meticulously followed.
Technical Troubleshooting & Problem-Solving: Serve as the first line of defense and primary technical expert for resolving complex processing issues, equipment malfunctions, and quality concerns on the production floor.
Performance Monitoring & Reporting: Track, analyze, and report on key departmental metrics (e.g., efficiency, scrap rates, downtime, labor variance) to plant management, identifying trends and developing actionable improvement plans.
Staff Training & Skill Enhancement: Identify skill gaps within the team and develop or facilitate training programs for molding processes, machine operation, safety procedures, and quality checks to ensure a highly competent workforce.
Equipment & Tooling Management: Collaborate with the maintenance and tooling departments to schedule preventative maintenance, communicate repair needs, and ensure the proper care and handling of all molds, machines, and auxiliary equipment.
Resource Management & Allocation: Effectively manage labor, materials, and equipment resources across the shift to maximize productivity and adapt to changing production demands or unforeseen challenges.
Documentation & Record Keeping: Ensure accurate and timely completion of all production-related documentation, including setup sheets, process logs, production reports, and quality records, maintaining data integrity within the ERP/MES system.

Secondary Functions

Continuous Improvement Leadership: Actively lead and participate in Kaizen events, 5S initiatives, and other lean manufacturing projects aimed at improving operational efficiency, reducing waste, and lowering production costs.
Cross-Functional Collaboration: Partner with Quality, Engineering, Maintenance, and Supply Chain departments to resolve issues, support new product introductions (NPI), and implement process improvements.
Budgetary Input & Cost Control: Provide input for the departmental budget and actively manage operational costs, including labor, materials, and supplies, to stay within financial targets.
New Technology Evaluation: Assist in the evaluation and implementation of new molding technologies, automation, robotics, and auxiliary equipment to enhance departmental capabilities.
Audit Support: Represent the molding department during internal and external audits (e.g., ISO, IATF, customer audits), ensuring all processes and documentation are compliant.
Material Handling & Logistics: Oversee the proper handling, drying, and blending of raw plastic materials to prevent contamination and ensure process consistency.
Emergency Response Coordination: Act as a key leader during plant emergencies, directing personnel and executing established emergency action plans.
Mentorship of Future Leaders: Identify and mentor high-potential employees, providing them with opportunities and guidance to prepare them for future leadership roles within the organization.
