Mold Flow Engineer

Responsibilities

• Perform Moldflow simulations (Fill, Pack, Warp, Cooling and Fibre Orientation) to support component and tooling design
• Create high-quality meshed models and build representative Moldflow models incorporating cooling channels, inserts and feed systems
• Analyse results and provide clear, actionable engineering guidance to design, tooling and production teams
• Identify moulding and tooling risks using 'what-if' and sensitivity studies, defining mitigation actions
• Optimise gating strategies, runner layouts, cooling circuits and cycle times using simulation
• Support Design for Manufacture (DFM) reviews and collaborate with tooling engineers on mould design and material selection
• Produce technical reports and present analysis results to internal stakeholders and customers
• Participate in tooling GA reviews and mould trials, correlating simulation predictions with actual tool performance
• Support root-cause analysis of moulding defects using Moldflow outputs and validation data
• Develop and maintain Moldflow best practices, libraries, templates and workflows

Requirements

• Proven experience performing Moldflow simulation for injection-moulded plastic components
• Ability to create fully meshed part and tool models, including complex tool features
• Solid understanding of plastic component design, mould tool design and injection-moulding processes
• Strong knowledge of thermoplastics, fibre-filled materials, shrinkage modelling and warpage control
• Excellent analytical and problem-solving capability
• Clear written and verbal communication skills, able to explain complex results to non-specialist audiences
• Ability to manage multiple simulation tasks within cross-functional engineering teams
• Experience working with toolmakers or injection-moulding suppliers

Preferred Qualifications

• Experience correlating simulation outputs with mould trial results
• Familiarity with DOE methods, optimisation studies or additional CAE tools
• Strong proficiency in Autodesk Moldflow Insight
• Degree (or equivalent experience) in Mechanical, Plastics, Manufacturing or Materials Engineering
• Knowledge of GD&T, DFM, DFA or tolerance analysis
