Engineering before steel. Every program starts with a design-for-manufacturing review: draft, wall thickness, gates, shrink and tolerance stack, before a tool is cut.
Production in Phoenix. Multi-cavity and family molds, in-process inspection and scheduled releases from a plant 180 miles from the Mexican border and a day’s freight from the whole Southwest.
Tooling you own. We design and manage your mold, build it through our vetted tooling partners, and maintain it in Phoenix for the life of the program.
A domestic alternative that pencils out. No tariff exposure, no eight-week ocean transit, no quality trips overseas. Lead times run two to six weeks instead of eight to sixteen.
