Prototype Metal Casting

Prototype metal castings have numerous advantages when utilizing a wide range of prototyping technologies such as; die-casting, investment casting, precision sand casting, and rubber plaster mold casting.

While these metal parts are custom to the requirements of a customer alloy specifications, using the same grade materials the end use components will be produced in and with same production method is used to mimic processes.

Since these processes each have their own advantages and disadvantages because of the engineering application specifications of each method they will vary. The typical casting processes ranges from using an SLA master pattern and molding positive and negative molds to make final cast part. Also used for these processes is lost foam or wax, match plate or parting board.

  • Shorten your time-to-market
  • Demonstrate a new product design
  • Reduce development mechanical design engineering flaws
  • Wide range of ferrous or non-ferrous alloys

Prototypes depending on the alloy are done by forcing low or high molten metal under pressure and into molded cavities. Most castings are either made using ferrous or non-ferrous alloys. These alloys are various types and grade such as aluminum, iron, magnesium, steel, and zinc.

While the metal options are not always absolute, each project is manufactured differently. The surface finishes typically range in this manner, 63-125 RMS for investment, 200-250 RMS for precision sand, 63 RMS for die-cast, and 63-125 RMS for plaster mold cast parts.

Ferrous and non-ferrous alloys because there can be several cavities in a die, producing multiple cast component per shot and even though with these highly refined processes there is still some porosity issues. We offer secondary operations to produce features not readily castable, like CNC machining, drilling, heat treating, casting impregnation, tapping holes, polishing, plating, buffing, and painting are available.
