The Casting Difference

The RLM Investment Casting process offers many benefits over other types of casting processes including:

  • Low Initial Tooling Costs – Initial tooling costs averaged over the parts produced are often less than other manufacturing tool costs.
  • Elimination of Material Waste – Investment castings are cast to size, decreasing the amount of machining required.
  • Design Flexibility and Capability – Infinite choice of alloys and design flexibility for internal and external configurations. Virtually any shape or configuration can be investment cast, producing internally complex parts.
  • Design Enhancements – There are no draft requirements in the investment casting process.
  • Consistency – Our process gives a reliable and consistent product from order to order.
  • Close Tolerances – RLM’s typical linear tolerances can be plus or minus .005 in per inch. However, closer tolerances are frequently achieved on selected dimensions, depending on the alloy and configuration of the part.
  • Surface Finish Improvement – A surface finish of about 125RMS is standard for our investment castings.
  • Reproduction of fine details – Holes, bosses, and splines can be cast
  • Reduction of production costs – Costly machining operations can often be eliminated.
  • Reduction of assembly operations – Several parts can be made as a single casting, reducing assembly and handling costs.
