Program Management

We will manage your entire program from “Prints to Parts”.

We will take your CAD/prints and design the entire tooling package to ensure you get the right tool to maximize your investment.  After the tooling phase, our die cast process engineers will develop the optimum process parameters to ensure the highest quality parts to meet your part quality specifications.  With our in-house machining capabilities and/or the vast array of approved local suppliers, we will make sure that your parts are finished precisely to specification and delivered exactly on time.
