• Prepare detailed 3D mould assemblies and 2D manufacturing drawings using CAD software.  

• Ensure designs are accurate, manufacturable, and aligned with engineering standards.  

2. DFM & Design Validation  

• Perform detailed DFM (Design for Manufacturability) analysis and identify potential moulding and manufacturing issues.  

• Recommend suitable design solutions to improve mould performance, manufacturability, and component quality.  

• Assist in mould flow analysis and interpret simulation results where required.  

• Review product designs and provide inputs regarding draft, wall thickness, parting line, undercuts, and other moulding considerations.  

3. Technical Problem Solving  

• Identify and resolve technical challenges related to mould design, machining, assembly, and mould trials.  

• Support Tool Room and Production teams in resolving design-related issues during manufacturing and assembly.  

• Analyse mould trial feedback and implement necessary design modifications.  

• Ensure design changes are properly evaluated and documented.  

4. Advanced Technical Expertise  

• Apply knowledge of mould materials, machining processes, plastic injection moulding principles, and industry standards.  

• Calculate and verify critical dimensions, tolerances, fits, clearances, and component requirements.  

• Select appropriate standard mould components such as ejector pins, guide pillars, bushes, springs, locks, and other tooling components.  

• Use CAD and simulation software such as SolidWorks, NX, AutoCAD, and Moldflow as applicable.  

5. Review & Support Junior Designers  

• Review designs, drawings, and models prepared by Junior Tool Designers.  

• Provide technical guidance and constructive feedback to improve design quality.  

• Support junior designers in DFM analysis, mould component selection, and design problem-solving.  

• Ensure drawings released for manufacturing meet required quality and accuracy standards.  

6. Coordination & Communication  

• Coordinate with Assistant HOD / HOD, Tool Room, Production, Quality, and other departments for smooth execution of mould projects.  

• Communicate technical issues, design changes, and improvement suggestions effectively.  

• Participate in design reviews, project meetings, and technical discussions.  

• Provide necessary technical clarification to manufacturing and assembly teams.  

7. Continuous Improvement  

• Identify opportunities to improve mould design, manufacturing efficiency, mould life, and overall tooling performance.  

• Suggest innovative and cost-effective solutions for existing and new mould designs.  

• Standardize frequently used mould components and design practices wherever applicable.  

• Support implementation of lessons learned from previous mould projects.  

8. Documentation & Reporting  

• Maintain accurate design records, drawing revisions, design change requests, and project documentation.  

• Prepare DFM reports, design review reports, technical specifications, and other required documentation.  

• Ensure proper revision control and timely release of drawings for manufacturing.  

• Maintain design standards and ensure all required documents are updated and traceable.  

Qualifications & Requirements  

• Education: Diploma / Post Diploma / Bachelor's Degree in Tool Design, Tool & Die Making, Mechanical Engineering, or a related field.  

• Experience: Minimum 4–6 years of relevant experience in plastic injection mould design.  

• Preferred Background: Experience in designing complex injection moulds and working directly with Tool Room / mould manufacturing teams.  

Preferred Skills  

• Strong hands-on experience in plastic injection mould design.  

• Advanced knowledge of SolidWorks or similar 3D CAD software.  

• Proficiency in Creo, NX, AutoCAD, and Moldflow is an added advantage.  

• Strong understanding of plastic injection moulding processes and mould components.  

• Solid knowledge of DFM principles, mould materials, machining processes, tolerances, and fits.  

• Excellent ability to read and interpret product drawings and engineering specifications.
