Mechanical Product Development | DFM, Tooling & Manufacturin

Many plastic parts can be modeled in CAD. Far fewer successfully make the transition into stable, repeatable production. This project involved the complete development of a multi-cavity injection molding system, from product design and DFM review through mold flow analysis, tooling development, mold trials, and production launch. As the project lead, I coordinated product engineering, tooling design, manufacturing support, and process validation to reduce production risk before mass manufacturing. Flow analysis and runner balancing were used to optimize cavity filling and improve process stability prior to cutting steel. The result was a production-proven injection molding program that successfully moved from concept and CAD development to molded production parts. Projects like this sit at the intersection of product development, tooling engineering, and manufacturing execution.

Hydraulic Punching Machine for Deep Drawn Stainless Steel Production High-volume production of deep drawn stainless steel components often requires secondary operations that must maintain tight dimensional accuracy without deforming the formed part. This project involved developing a custom hydraulic punching machine capable of delivering precise, repeatable punching while supporting reliable mass production. As the technical lead, I was responsible for the complete engineering process, including machine architecture, structural calculations, FEA validation, hydraulic system design, manufacturing process development, tooling and die design, detailed mechanical design, and production documentation. The machine was engineered to achieve stable production, minimize part deformation, simplify maintenance, and ensure long-term manufacturing reliability. Beyond the mechanical design itself, the project focused on creating a production-ready solution that balanced performance, manufacturability, tooling complexity, and operating efficiency. Responsibilities Product & manufacturing equipment development Machine architecture and mechanical design Structural calculation and FEA validation Hydraulic system development Tooling & die design Manufacturing process development Production engineering documentation

6061 Aluminum BBQ Grill Plate – Product Development for Mass Production Led the mechanical development and tooling engineering for a deep-drawn 6061 aluminum grill plate. The project included CAD design, formability analysis, springback compensation, die face optimization, tooling design, and production trials. Every design decision was validated against real manufacturing constraints, resulting in a stable production process and production-ready tooling.

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.
