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.

Many wire forming projects fail not because of the final geometry, but because of incorrect forming sequences, uncontrolled springback, tooling interference, or poor production repeatability.
This project involved the complete development of a wire forming die system, from product definition and forming strategy through tooling design, manufacturing, tryout, and production implementation.
As project lead, I developed the forming sequence, springback compensation strategy, tooling architecture, and manufacturing validation process to ensure the product could be produced consistently at volume rather than simply formed in simulation.
The result was a production-ready wire forming solution capable of transforming straight steel wire into a complex multi-bend component through a controlled single-cycle forming process.

Successful tooling projects are rarely defined by CAD geometry alone. They depend on understanding material behavior, forming sequence, springback, tooling durability, and production repeatability.
This project involved the complete development of a cam-driven ring forming die, from product definition and forming strategy through tooling design, manufacturing, tryout, and production launch.
As project lead, I coordinated product engineering, forming development, tooling design, and manufacturing execution to ensure the process could run reliably in production rather than simply function in simulation.
The result was a production-ready forming system capable of generating consistent parts through a single-cycle forming process.
Projects like this are where product development, tooling engineering, and manufacturing reality intersect.

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.

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.

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.

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.

Compact folding phone stand developed for CNC machining and production.
The challenge was not creating a stand that holds a phone. The challenge was integrating a stable support structure, magnetic retention, folding mechanism, and clean industrial design into a compact aluminum body only 9 mm thick when closed.
The design was developed around CNC manufacturing constraints, assembly simplicity, durability, and everyday usability rather than concept rendering alone.
Projects like this sit at the intersection of product design, mechanical engineering, and manufacturing readiness.
