Armstrong Mold Corp.

One-Shot Casting Process

Rubber Plaster Molding (RPM) has been a staple at Armstrong RM since the business was founded. It is a fast and affordable alternative to investment casting, sand casting and prototype die casting of non-ferrous alloys. But it has one constraint: foundry tooling. To accelerate the process, lower the upfront investment and increase design flexibility, Armstrong RM has put a new twist on a mature process.

One-Shot Casting eliminates the need for foundry tooling. Plaster molds are poured directly from laser-sintered models, which are burned out of the mold after the plaster has set. This makes the process faster and less expensive for small orders of aluminum, zinc or magnesium castings.

• Al, Zn or Mg parts in 1 to 2 weeks.
• Ideal for 1 to 10 castings.
• No limits on design.
• No cost or added time for design modifications.
• Simulates die casting properties and appearance.
