With complex mechanical designs, a prototype is often built to test the functionality of the design concept, as well as address details such as tolerances and interference fits. The cost and schedule impact of contracting this work out on a regular basis is often prohibitive. CONAX Florida Corporation uses an in-house model/machine shop to build prototypes and has consequently realized additional benefits.

The company maintains a full-scale prototype model shop that includes such equipment as a lathe, drill press, milling machines, surface and offhand pedestal grinders, and band saw. The model shop which has been in operation since 1989 provides for several needed capabilities including the ability to generate and modify prototype hardware prior to development and release of supplier quality drawings. Additional advantages include early feedback from an experienced machinist on design-related problems, the ability to cross section and evaluate assemblies, an in-house rework capability, and in-house assembly and test fixture manufacturing capability.

As an example of this model shop advantage, CONAX Florida Corporation was required to build a prototype and prove a design before the customer would enter into a commitment. If the model shop had not been available, substantial resources would have been needed to develop detailed drawings, and a lengthy procurement process would have occurred, possibly requiring several iterative steps for corrections and explanation. By utilizing the internal expertise and familiarity with the product contained in the model shop, the prototype was constructed in about three weeks and in a cost effective manner. The design was proven and CONAX Florida Corporation was awarded a contract to manufacture the product in greater quantities.
