About Ragini Sinha

About: A goal-oriented professional with over 14 years of industry experience specializing in product design and development, I have established myself as a principal executive and the key point of contact for New Product Development (NPD) activities. My role involves overseeing the complete gamut of NPD processes, including process design, prototype development, testing, and manufacturing, all tailored to meet customer-specific requirements and drawings. I possess deep expertise in designing low voltage switches, with a strong focus on tolerance analysis, stack-up analysis, and Geometric Dimensioning and Tolerancing (GD & T). My proficiency extends to ensuring precision and reliability in product designs, particularly in plastic and sheet metal components. My extensive experience with CAD software such as AutoCAD, Solid Edge, and ProE Creo has enabled me to create detailed 3D models, assemblies, and technical drawings for switchgear products. Additionally, I am highly skilled in Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP) documentation, successfully managing multiple audits and training teams to ensure compliance and operational excellence. I specialize in diagnosing and resolving complex product issues, including fault analysis and failure mode analysis, and implementing corrective actions to enhance product reliability and performance. My proven ability to manage the entire lifecycle of product design projects—from initial concept and design through prototyping, testing, and final production—demonstrates my expertise in resource allocation, time management, and cross-functional team coordination. My experience also includes conducting rigorous testing and validation of switchgear designs, such as type testing, routine testing, and acceptance testing. I am adept at making necessary design adjustments based on test outcomes, ensuring that all products meet stringent safety and performance standards. My in-depth knowledge of material properties and behavior under various electrical stresses supports my proficiency in selecting appropriate materials for component durability and effective thermal management. Finally, my expertise in industry standards and regulations, including IS 3854 for switches, IS 1293 for sockets, and IEC standards, ensures that all designs comply with stringent requirements, contributing to the safety and performance of the products I develop.
