Mechanical Product Development | DFM, Tooling & Manufacturin

A plastic part is easy to model in CAD. Producing it consistently across multiple cavities is where the real engineering begins. This project involved the complete development of a production injection molding system, including DFM review, mold flow analysis, runner balancing, multi-cavity tooling development, and production validation. The objective was to identify manufacturing risks before steel was cut, improve cavity balance, reduce molding variation, and achieve a smooth transition from CAD design to production parts. Projects like this sit at the intersection of product development, tooling engineering, and manufacturing reality.

Many stamping problems are not caused by the tool itself. They originate from forming behavior, material flow, springback, and process decisions made long before production starts. This project covered the complete development cycle of a progressive die system, including forming analysis, strip layout optimization, tooling development, manufacturing support, and production launch. The objective was not simply to create a working die, but to reduce production risk, improve process stability, and achieve consistent part quality at volume. Projects like this are where mechanical design, tooling engineering, and manufacturing reality come together.

Many structural failures are not caused by insufficient material. They are caused by poor load management. This mountain bike frame development project focused on understanding load paths, validating boundary conditions, identifying stress concentration areas, and refining geometry through Finite Element Analysis (FEA). The objective was not simply to generate simulation results, but to use those results to make better engineering decisions before prototype and production investment. Services involved: • Product Development • Mechanical Engineering • FEA Simulation • Structural Analysis • Design Optimization • Manufacturing-Oriented Engineering

Many sheet metal components appear simple, but achieving stable production requires careful control of material flow, blank holding force, forming geometry, springback, and tooling design. This project involved the complete development of a sheet metal forming system, from product development and forming strategy through tooling design, manufacturing, tryout, and production implementation. As project lead, I was responsible for product engineering, process development, tooling design, manufacturing support, and production validation. The tooling combined blanking and forming operations within a single system to improve production efficiency while maintaining dimensional consistency and part quality. The project required balancing manufacturability, tooling durability, production repeatability, and cost efficiency to ensure reliable mass production. Projects like this are where product development, tooling engineering, and manufacturing execution come together.
