Plastic Injection Mold Designer

Qualification: Diploma / Degree in Mechanical Engineering or ITI (Mechanical/Tool & Die) Key Responsibilities: Review and analyze product designs for manufacturability (DFM) specific to plastic injection molding. Design and develop molds and tools for plastic parts, ensuring adherence to product specifications and cost targets. Select appropriate mold materials (e.g., P20, H13, S7, etc.) based on part requirements and production volume. Evaluate and recommend suitable molding materials (e.g., ABS, PC, PP, Nylon, etc.) considering application, performance, and cost. Prepare detailed 2D/3D tool and part drawings using CAD software (SolidWorks/AutoCAD/UG/NX/Catia). Collaborate with product designers to suggest design modifications for improved manufacturability and tool life. Conduct mold flow analysis, gate location selection, cooling channel design, and parting line definition. Troubleshoot and resolve issues during mold trials and production, including warpage, sink marks, and short shots. Coordinate with toolmakers, vendors, and production teams for mold fabrication, assembly, and validation. Ensure compliance with dimensional accuracy, tolerances, and quality standards. Prepare and maintain comprehensive technical documentation, BOM, and design records. Key Skills & Requirements: Strong understanding of DFM principles for injection molded parts. Proficiency in designing injection molds, including multi-cavity and family molds. Hands-on experience with various mold steels (P20, H13, S7, etc.) and plastic materials (ABS, PC, PP, Nylon, etc.). In-depth knowledge of mold flow analysis, cooling system design, and ejection mechanisms. Experience with CAD software (SolidWorks, AutoCAD, UG/NX, Catia, or similar). Ability to interpret and generate technical drawings and GD&T. Excellent problem-solving skills and ability to suggest design/process improvements. Effective communication and coordination with cross-functional teams. Strong attention to detail and quality orientation. Preferred: Exposure to rapid prototyping, 3D printing for trial parts, and advanced manufacturing techniques. Experience in mold maintenance, repair, and modification. Candidates with exposure to other process like vacuum casting and thermoforming will be given preference.
